Press Release (March 18th, 2010 )
New cfos IPv6 Link v2.50 with major features!
Connectivity with the new IPv6 network.
cfos IPv6 Link allows dial-up with IPv6 for Windows XP and Vista. Simply configure the dial-up connection to your ISP and you're IPv6-ready! Not only does cfos IPv6 Link connect to the new IPv6 network, but it also configures routing and IP and DNS addresses automatically.
Major features of the new version are:
- NAT46 mapping. This allows IPv4-only software to be used with IPv6. To accomplish this, cfos IPv6 Link maps the IPv4 addresses to IPv6 addresses (and vice-versa). cfos IPv6 Link supports NAT46 for outgoing as well as incoming connections. This allows easy migration from IPv4 to IPv6.
- cfos IPv6 Link now supports multiple address prefixes, e.g. by Router Advertisement or DHCPv6 (prefix delegation), as well as statically assigned prefixes. Also cfos IPv6 Link now supports policy table updates according to RFC 3484 by means of DHCPv6 option OPTION_DASP.
- cfos IPv6 Link now supports DHCPv6 custom options. Third party applications, like ISPs dial-up software, can now query cfos IPv6 Link for DHCPv6 options (stateful and stateless) and use them to configure the system.
You can find artwork, screenshots and boxshots which may be used for free by journalists at http://www.cfos.com/presse/vorlagen.htm .
cfos IPv6 Link is available either as a 30-day trial version (which can be downloaded for free at http://www.cfos.com/download/download_e.htm ) or as the full version for €29,90.

Press Release (October 28th, 2009)
cFosSpeed, new Version 5.00, now with real-time Traffic Analysis & new Pinger!
cFosSpeed is a network driver which attaches itself to existing Internet connections. It optimises data transfer by means of Traffic Shaping. Traffic Shaping is a method for optimising Internet traffic that allows maximum transfer speed while ensuring minimal ping time.
cFosSpeed supports a wide variety of connection types like DSL, cable, UMTS, ISDN, etc.
The most important improvements of this version are:
- Real-time Traffic Analysis: cFosSpeed can analyse traffic for different protocols and used programs and visualize these different traffic streams graphically in real-time. To do that there are two new status windows and a new dialog, by which the user can setup the assignment of different traffic streams to the respective graphs. This allows detailed analysis and thus comprehensive knowledge which traffic streams use how much bandwidth.
- New dynamic Ping Engine: for traffic shaping to function properly, cFosSpeed must know when the Internet connection begins to congest, i.e. when the ping time to the next hop begins to increase. This is now probed in a much more reliable and much more precise way. cFosSpeed can now simultaneously use up to 5 different ping variants, each for different hops respectively: ICMP, UDP and TCP in kernel-mode and ICMP, UDP in user-mode. Thereby the pings can pass common firewalls and filters in routers more reliably. cFosSpeed can even switch from one pinger to another dynamically during normal operations.
- cFosSpeed is Windows 7 compatible.
- Complete optical overhaul of the user interface; adapted to Vista / Windows 7.
- More improvements of the Layer-7 Protocol Analysis, especially the RTP (Voice over IP) and SSL / SSH (Bulk Mode) detection.
- IP filter-lists now support the Protowall / Peerguardian format.
- Lots of further improvements, see WHATSNEW.TXT.
You can find artwork, screenshots and boxshots which may be used for free by journalists at http://www.cfos.com/presse/vorlagen.htm .
cFosSpeed is available either as a 30-day trial version (which can be downloaded for free at http://www.cfos.com/download/download_e.htm ) or as the full version for €14,90.

Press Release (February 11th, 2009)
cFosSpeed, new Version 4.50 now with prioritisation for web-surfing.
cFosSpeed is a network driver which attaches itself to existing Internet connections. It optimises data transfer by means of Traffic Shaping. Traffic Shaping is a method for optimising Internet traffic. It allows maximum speed while ensuring minimal ping..
cFosSpeed supports a wide variety of connection types, like DSL, cable, ISDN, UMTS, etc.
Important feature of this version is the differentiation between HTTP web-surfing and HTTP downloads. Thereby cFosSpeed can give web-surfung precedence and limit the bandwidth for HTTP downloads. Web-surfing is an interactive Internet use and needs a responsive connection while HTTP downloads can usually be limited, if the available bandwidth is required for more important tasks. With the dialog for protocol prioritisation the user can adjust the precedence of HTTP accordingly.

Press Release (July 23rd, 2008)
cFos IPv6 Link, Connectivity with the new IPv6.
cFos IPv6 Link allows Dial-Up with IPv6 for Windows XP und Vista. While Vista partly supports PPP Dial-Up into the IPv6, Windows XP has no PPP stack capable of IPv6 dial-up. In this case cFos IPv6 Link offers users of Windows XP to connect to the IPv6 network. Also under Windows Vista there are great advantages. For example it handles the automatic configuration of all connection parameters and is much faster than the driver shipped with Vista.
Everyone who wants to try cFos IPv6 Link, can use it with a DSL modem or an IPv4 router, which supports PPPoE-Passthrough.
cFos IPv6 Link supports the typical IPv6 address- and routing auto-configuration with
- Pv6 Neighbor discovery (ND) + DAD
- IPv6 Router Advertisement
- IPv6 DHCP (DHCPv6) statefull & stateless
- IPv6 Router Solicitation with ISP
- DHCPv6 with ISP
In addition cFos IPv6 Link has a DNS mapper, which translates IPv4- and IPv6 DNS queries into queries for the IPv6 and into IPv4 if no IPv6 DNS server is known.
cFos IPv6 Link is available either as a 30-day trial version (which can be downloaded for free at http://www.cfos.com/download/download_e.htm ) or as the full version for €29,- .

Press Release (June 20th, 2007)
cFosSpeed v4.0, Traffic Shaping with Multi-User Mode!
cFosSpeed is a network driver that optimises data transfer through Traffic Shaping. This technology allows cFosSpeed to minimise ping times while ensuring maximum data throughput and Voice-over-IP quality. For more information see http://www.cfos.de/techinfo/shape_e.htm
Highlights of the new version include:
- Multi-User Mode:
The new Traffic Shaping in cFosSpeed allows use of several PCs connected to one router. In this scenario the available bandwidth can change rapidly. cFosSpeed detects such changes and manages the data transfer so that ping times are good and no PC chokes another.
One Traffic Shaping variant provides good results even if there is a PC in the network with no cFosSpeed Traffic Shaping, e.g. Linux or Playstation.
In Multi-User mode there may be the need to restrict the throughput of an individual PC. Therefore cFosSpeed now offers fixed bandwidth limits. You can then, for example, reserve a minimum bandwidth for other PCs with interactive applications.
Our WHATSNEW.TXT provides a full list of changes.
cFosSpeed is available either as a 30-day trial version (which can be downloaded for free at http://www.cfos.de/download/download_e.htm) or as the full cFosSpeed/Professional version, currently starting at a special offer price of €9,95.

cFosSpeed v3.10, important update for Bittorrent users!
cFosSpeed is a network driver that optimizes data transfer through Traffic Shaping. This technology allows cFosSpeed to minimize ping times while ensuring maximum data throughput and Voice-over-IP quality. For more information see http://www.cfos.de/techinfo/shape_e.htm
Highlights of the new version include::
- Not only does cFosSpeed Traffic Shaping manage upstream data traffic, but it also controls downstream data reception. This new type of RX shaping is even better suited to support peer-to-peer applications with multiple connections running at the same time. As a result, even with as many as 500 connections already open, additional Internet applications can still be run with ease.
- The cFos online budgets to keep track of time spent online and volume used has now been integrated into cFosSpeed as well. This is particularly useful for those on broadband without a flat rate. In addition, data traffic is now presented in graphical format, making it possible to have different graphics displayed for budgets, programs, and protocols used.
- Tested for both 32-bit and 64-bit Vista Beta 2.
- A host of minor improvements including additional options for routing and IP configuration plus a new status-window control panel.

Press Release June 02, 2006
cFos v7.0 64-bit ISDN and DSL Driver uncovered!
Following up on its initial finds of 16-bit CAPI FOSSILS in early DOS deposits and later discoveries of 32-bit specimens in Windolithic layers, a team of cFos-O-logists led by Chris Lueders and Martin Winkler have now unearthed a 64-bit version of this once widespread genus of ISDN and DSL drivers in the skeletal remains of a recently excavated x64 Windosaurus. This proves that the cFos family belonged to only a select few driver species that succeeded in doubling bitwidth twice during their evolution
Hailed as a sensational find, this also calls into question long-established theories that posit such software had been under threat of extinction with the imminent rise of broadband networks. Windologists cite an amazing adaptability to new developments in telecommunications as the primary reason for the enduring popularity of cFos drivers. The ability to establish symbiotic relationships with both time-tested software and new technologies seems to have been of utmost importance for this. Thus, not only could the 64-bit drivers link up with ISDN cards still extant at that time, but they did also optimize the performance of broadband networks – by letting them achieve higher data throughput and low ping times through Traffic Shaping.
By participating in a 30-day trial program, eager scientists now hope to find out more about unique abilities exhibited by the latest CAPI fossil, such as:
- fully integrated 64-bit support (including 64-bit Kernel-Mode CAPI and CAPI2064.DLL)
- Traffic Shaping with Layer-7 protocol detection: Recognition of the 25 most important protocols
(including HTTP, FTP, POP3, filesharing/P2P, streaming media, and VoIP) - adaptivity to high-end bandwidth (like ADSL2+)
- Traffic Shaping for ISDN
- numerous other evolutionary leaps like advanced Multilink-PPP support and a fully switchable firewall
However, prior to any such research, the 64-bit version must first be downloaded in full from:
www.cfos.com/download/download_e.htm
cFos-O-logists under the leadership of Chris Lueders and Martin Winkler have been researching the development and evolutionary history of cFos drivers in disparate habitats for more than 13 years. The main scientific focus has always been on different adaptation techniques to new conditions. One such strategy is Traffic Shaping, which has been successfully demonstrated for both cFos and cFosSpeed.Website: www.cfos.com

Press Release May 15, 2006
cFosSpeed v3.0 major update with tons of new features and functions!
cFosSpeed is a network driver that optimizes data transfer through Traffic Shaping. This technology allows cFosSpeed to minimize ping times while ensuring maximum data throughput and Voice-over-IP quality. For more information see http://www.cfos.de/techinfo/shape_e.htm
Highlights of the new version include:
- Layer 7 protocol detection: cFosSpeed detects which protocols
are being used based on packet content not on port numbers.
This provides users with a quick and easy way to configure data traffic down to the last minutiae. The following protocols can be prioritized in this fashion:
Standard protocols: HTTP, FTP, POP3, SMTP, IMAP4
Voice-over-IP: RTP, RTCP, SIP
Special protocols: Telnet, SSH, SSL, IRC, DNS, (S)NTP, RPC
Filesharing/P2P: eDonkey, Kazaa, Bittorrent, Kademlia, Gnutella(2), Direct Connect Streaming media: RTSP and HTTP streams with miscellaneous player software.
All protocols can be prioritized individually. The cFosSpeed console window provides a realtime overview of all active connections and protocols.
This also means that cFosSpeed can use Internet Connection Sharing (ICS) to prioritize the data traffic of multiple users simultaneously. - The new connectivity engine makes it possible to run multiple Internet connections at the same time - each with different Traffic Shaping settings. It also permits use of VPN and routing for RAS (RRAS).
- For optimal Traffic Shaping configuration, cFosSpeed now fully supports all of the following broadband media: PPPoE, PPPoA (LLC & VCmux), PPTP, Cable, ISDN, and IP over AAL5.
- Full 64-bit support for all Windows x64 editions. All cFosSpeed components are fully 64-bit capable.
- Switchable firewall function with packet filtering, state inspection, stealth mode, plus optional ingress and egress filtering. This makes cFosSpeed one of the few firewall solutions available for x64!
- Traffic Shaping for ISDN.
- Numerous minor Traffic Shaping improvements for ensuring ping times are kept to a minimum while transfer rates remain at max. Among other additional features, cFosSpeed does now support IP fragmentation.
- New fine-tuning dialogues.
The WHATSNEW.TXT provides an itemized list of all changes (running more than 250 lines total).

Press Release May 25, 2005
cFos v6.0 now with new Traffic Shaping technology!
Important updates and new features:
- New Traffic Shaping with programmable rules.
Traffic Shaping yields optimal Ping times while ensuring maximum Upload and Download Rates. This is achieved in three ways:
It reprioritizes data packets in such a fashion that optimal transfer rates are achieved (ACKs, for instance, are sent out prior to other data). By default, cFos Traffic Shaping manages six priority queues. In doing so, it differentiates between various protocols (such as HTTP, FTP, POP3, SMTP, ICMP, SSH, Telnet, DNS, etc.) and reprioritizes them accordingly. This is to make sure that different applications will interfere with each other as little as possible.
The data stream is realigned in such a way that as little congestion as possible occurs, allowing ping times to remain low. This will in turn result in fast response times while surfing the Net or playing online.
The ACK filtering employed by cFos effectively halves the bandwidth needed for sending ACKs. Additional bandwidth is thus freed up and becomes available for uploads!
More details including test results can be found at http://www.cfos.com/traffic_shaping/traffic_shaping_e.htm . Besides printable material, you will also find an animated graphic there showing how Traffic Shaping technology works.
- Individual program prioritization
Since programs can easily be prioritized up or down individually, cFosSpeed Traffic Shaping allows users to get the most out of online games, filesharing programs, voice-over-IP and other multimedia applications. This way, gamers will benefit from lower ping times, while filesharing programs can be run in the background without choking a connection's upstream channel.
- Further new features:
Redesigned firewall with programmable rules
Icon Skins; display cFos status in the taskbar
New languages: French, Spanish, Japanese and Korean
- More upstream bandwidth
By optimizing TCP ACKS during downloads, the new cFosSpeed ACK filter increases available upstream bandwidth dramatically, often even tripling it. Since TCP ACKs take up roughly one-tenth of a download's bandwidth in the upload channel, a DSL 2000 connection with an upstream of 192 kbps could for instance not quite achieve full download speed until now. But with cFosSpeed this is finally possible! For DSL 2000, there are now approximately 13 kbps available for uploads during a full download. For a DSL 1000 connection, available upload bandwidth is doubled from 6 to 12 kpbs.
- Individual program prioritization
Since programs can easily be prioritized up or down individually, cFosSpeed Traffic Shaping allows users to get the most out of online games, filesharing programs, voice-over-IP and other multimedia applications. This way, gamers will benefit from lower ping times, while filesharing programs can be run in the background without choking a connection's upstream channel.
- Low-latency mode
Low ping times are especially vital for online games and voice over IP. In low-latency mode, cFosSpeed will still maximize available bandwidth but not at the expense of low ping times. In bandwidth mode, cFosSpeed minimizes ping times but without sacrificing available bandwidth. Some test results on this can be found in the WHATSNEW.TXT file. Thus, gamers who have already prioritized their online games can further decrease ping times during other ongoing traffic by switching to low-latency mode.
- Icon windows
For optimal integration with the user interface, cFosSpeed skin windows can now be included on the Windows taskbar. The new icon skin looks great!
- Improved language support
In addition to German, English, Polish, and (both traditional & simplified) Chinese, cFosSpeed is now also available in French, Spanish, Italian, Japanese, and Korean.
- Surf the Web up to three times faster than with conventional broadband drivers
- Reduce delays during data transfer significantly
- Thus making use of the full bandwidth of a DSL connection
- PPPoE drivers (such as cFos or the built in Windows XP PPPoE driver)
- USB DSL-Modems connected via USB WAN drivers
- Routers
- surf the Web up to three times faster than with conventional broadband drivers
- reduce delays during data transfer significantly
- and thus make use of the full DSL bandwidth
- firewall with state inspection
- call monitor and protection from expensive dialers programs
- channel bundling and all major ISDN protocols
- Bis zu dreimal schneller Surfen mit cFos Traffic Shaping!
- Neues Verfahren reduziert Wartezeiten beim Datentransfer
- Endlich die volle Bandbreite des DSL Anschlusses ausnutzen
- cFos Traffic Shaping:
Erste echte Surfbeschleunigung unter Windows!
cFos Traffic Shaping sorgt dafür, dass die Bandbreite eines DSL-Anschlusses in beide Richtungen voll ausgenutzt wird und trotz Datentransfers keine hohen Wartezeiten beim Surfen auftreten.
cFos steuert das Zeitverhalten der TCP Verbindungen und verhindert so verlängerte Ping-Zeiten und damit verbundene Einbrüche in der Transferrate. Dafür müssen dank cFos weder einzelne Steams künstlich beschränkt werden, noch deren Bandbreite im Vorfeld bekannt sein.
Näheres, insbesondere eindrucksvolle Testergebnisse, finden sich auf http://www.cfos.de/traffic_shaping/traffic_shaping.htm
- Verbesserte "stateful" Firewall:
cFos enthält jetzt nicht nur einen Paketfilter, sondern auch eine "echte" Firewall, die den Zustand der TCP/IP Verbindungen überwacht.
Hinweis: Wir haben festgestellt, dass bei manchen lokalen Anbietern (besonders mit Flatrates) so viel Bandbreite mit eingehenden Verbindungsanfragen von File-Sharing Programmen verbraucht wird, dass die Antworten darauf die Upstream-Bandbreite übersteigen würden. Ohne Firewall kommt dies einer dauerhaften "Denial of Service" Attacke gleich. Mit Firewall werden diese Anfragen ignoriert und die Upstream Bandbreite bleibt für Nutzdaten erhalten.
- Zeit-Synchronisation nicht nur via ISDN, sondern auch via Internet
Time Server (mittels SNTP). Damit ist auch mit DSL die Rechner-Zeit
immer korrekt.
- Überarbeitetes Skin mit Alphablending und Farbtransformation.
- Smart Inactivity Timer: Als Aktivität werden jetzt nur noch Daten-
Transfers gezählt, die vom Benutzer initiiert wurden. Damit können
z.B. Port-Scans und unerwünschte Verbindungsanfragen das Auflegen bei
Inaktivität nicht mehr verhindern.
- Weitere Neuerungen siehe WHATSNEW.TXT der aktuellen cFos Version 5.0.
- wesentlich genauere Ping-Zeiten: Da Timings unter Windows Ungenauigkeiten von bis zu 10 Millisekunden aufweisen, taugt der Standard-Ping zum Ausmessen von High-Speed Anschluessen, wie z.B. DSL nichts. hrPING nutzt fuer alle Timings den in Pentium-Class Prozessoren eingebauten Instruction-Timer (TSC), der mit jedem Takt hochgezaehlt wird. Dadurch erzielt hrPING mikrosekunden-genaue Messungen. Dies ist z.B. wichtig, wenn man DSL Anschluesse ausmessen moechte, bei denen Fastpath (Ping-Zeiten von ein paar Millisekunden) oder Short-Interleave (Ping-Zeiten von ca. 10 msec.) geschaltet ist.
- verbesserte Statistiken: hrPing fuehrt ueber alle Pings Statistiken und ermittelt Minimum, Maximum und durchschnittliche Dauer. hrPING kann man hierbei im "Endlos-Modus" laufen lassen. Dann generiert hrPING solange Pings, bis man dies mit CTRL-C abbricht. Dann werden aber, im Gegensatz zum Standard-Ping ebenfalls Statistiken ausgegeben.
- Timings und Statistiken auch fuer ICMP Fehlermeldungen (z.B. TTL expired). Dies ist z.B. zum Ausmessen von Routen nuetzlich.
- Overlapped Pings, wie unter Linux ueblich: hrPING kann mehrere Pings gleichzeitig senden, ohne erst auf die Anwort der vorigen Pings zu warten.
- Eingebautes Traceroute
- Alle relevanten Parameter, z.B. Groesse der Ping-Pakete, TTL, Timeouts, sind einstellbar.
-
0190er-Blocker und neues Produkt names "cFos Watch":
Damit schützt cFos auf zweierlei Arten vor bösen Überraschungen durch teure Internet-Dialer.
cFos kann die Rufnummern aller cFos Modems überwachen und bietet zusätzliches DFÜ-Netzwerk Überwachung, so dass auch dann Schutz gewährleistet ist, wenn die Verbindung gar nicht über cFos aufgebaut ist, z.B. bei einem DSL Benutzer, der noch ein analoges Modem zum Fax- Empfang betreibt. In diesem Falle könnte ein Dialer nämlich versuchen, eine Verbindung über das Analogmodem aufzubauen, obwohl mit DSL selbst ja keine Wählverbindungen möglich sind.
cFos und cFos Watch bieten die Möglichkeit, bestimmte Vorwahlen ganz zu verbieten und andere in eine Liste zu warnender Nummern einzutragen. In diesem Fall zeigen cFos und cFos Watch eine Messagebox mit der Rufnummer an, so dass man im Einzelfall entscheiden kann, ob die Verbindung erlaubt ist.
cFos kann auch 010xx und 0100xx Call-by-Call Vorwahlen berücksichtigen, sowie gleichzeitiges Betreiben von Geräten mit und ohne Amtnetzkennzahl.
Die 0190er Blocker Funktionalität ist in die cFos Treiber eingebaut. Zusätzlich steht Überwachung der DFÜ-Netz Verbindungen in cFos Watch als separates Programm zur Verfügung.
Damit bieten wir auch eine Lösung für diejenigen, die cFos nicht nutzen, z.B. von Benutzer von Analogmodems.
-
Erweiterte Internet-Funktionalität durch "Minimum-Klick"
Setup Dialoge zur optimalen Einrichtung von DFÜ-Netz
Verbindungen über cFos, Inactivity Logout, schnellen Logoff im
cFos Kontextmenü, High-Speed Login, ...
-
Verbesserte Firewall Funktionalität
-
Anpassung an die kürzlich erfolgte Umstellung der Telekom
Breitband Knoten, so dass jetzt wieder der cFos High-Speed
Login allen zur Verfügung steht.
- einfache
Installation, ohne Reboot, mit automatischem Setup von DFÜ-Netzverbindungen.
Damit kann man innerhalb weniger Mausklicks online gehen.
- Optisch
ansprechende Benutzerschnittstelle und Statusfenster, kann die verbrauchte
Online-Zeit und Datenvolumen anzeigen, konfigurierbar mit Skins.
- Verbesserte
DSL/PPPoE Fähigkeiten, schneller, verbesserte Verbindungsüberwachung,
mehr PPPoE Optionen
- Unterstützung
der Windows XP Vorabversionen
- Unterstützung
von eingehenden GSM-Rufen (auch andere Mobilfunk-Netze)
- Verbindungsbericht
als HTML Dokument
- Unterstützung
von ISDN user-user info (z.B. für Calling-Card Anwendungen)
- 1&1 liefert eine spezielle DSL OEM-cFos Version aus
- die ISDN-Kooperation mit AOL wurde auf DSL ausgeweitet
- PCCW, Hongkong bietet ihren Kunden cFos als DSL-Lösung an
- Osnatel nutzt cFos als DSL-Treiber
- Mini-Firewall,
der die bekannten Windows-Sicherheitsprobleme in Verbindung mit NetBIOS-Ports
und Freigabediensten schließt. Weiterhin blockt cFos Denial-of-Service
Attacken, die gerade bei ADSL zu Verbindungsabbrüchen führen
können. Dies ist besondern für diejenigen gedacht, die sich
keine vollwertigen Firewall installieren möchten. Eine Erklärung
zum technischen Hintergrund des Mini-Firewall finden Sie hier.
- Volumen-Budgets.
cFos kann nun nicht nur die monatliche Online-Zeit,
sondern auch die Menge der übertragenen Daten ermitteln, so daß auch
für "Flatrate"-User, die nach Volumen abgerechnet werden, jederzeit Überblick über die Kosten besteht.
- Abhilfe
für überlaufene T-Online Knoten: Die Breitbandknoten,
aber auch
ISDN-Zugangknoten, lehnen bei Überlastung die PAP-Authentisierung
ab. Dies verhindert die automatische Neuwahl durch RAS. cFos sorgt in der neuen Version dafür, daß Windows neu anwählt und auch ein evtl. gespeichertes Passwort nicht jedesmal vergisst.
- Beschleunigter
Login mit DSL-Modem-Autodetection. cFos kann sich
bis zu dreimal schneller als konventionelle Treiber einloggen. Mit der neuen Version geht dies auch, wenn man mehrere Netzwerkkarten im System hat. cFos verwendet dann automatisch die Karte mit dem DSL-Modem.
- Unterstützung
von Internet-Connection Sharing. Zur Konfiguration
finden Sie eine Anleitung unter www.cfos.de.

Press Release February 18, 2005
cFosSpeed v2.0 now with next-generation Traffic Shaping technology!
Important updates and new features:
What exactly does Dynamic Traffic Shaping do?
In essence, it boosts download speed without sacrificing surfing speed - making cFosSpeed a true Internet accelerator for Windows!
cFosSpeed Traffic Shaping accomplishes this by making sure bidirectional DSL bandwith is optimally used so that delays during downloads can be kept to a minimum.
More specifically, it controls TCP connection timing, thereby cutting down on latency and the related drop in transfer rates. What's more, cFosSpeed does so without artificially limiting the bandwidth of individual data streams. Nor is it necessary to know in advance how much bandwidth will be taken up by each of those streams.

Press Release 17.10.2003
cFos Version 5.20 featuring advanced Internet tuning / Dynamic Traffic Shaping technology is out!
With it, users can:
So what is cFos?
cFos is a DSL and ISDN driver. As such, it can be used with the Dial-Up network and almost any modem program to communicate with ISDN and DSL (via PPPoE). What's more, cFos offers a wealth of features making it possible to get the max out of broadband connections.
On top of this, the new cFos 5.20 maintenance release is now fully Unicode compatible. It also comes with a multilanguage file that permits users to receive all important program messages in their respective mother tongue. English, German and Traditional Chinese are all available at present. Next in line will be Japanese.
What exactly does Dynamic Traffic Shaping do?
In essence, it boosts download speed without sacrificing surfing speed - making cFos the first true download accelerator for Windows!
Implemented since version 5.0, Dynamic Traffic Shaping accomplishes this by making sure bidirectional DSL bandwith is optimally used so that delays during downloads can be kept to a minimum.

Presseerklärung vom 16.1.2001
Neue cFos-Versionen / GmbH-Gründung / Freeware zum Download
Die cFos Lüders/Winkler GbR wurde zum Jahreswechsel in die cFos Software
GmbH umgewandelt. Anläßlich dieser Umstellung bringen wir folgende
Neuigkeiten:
1. Neue
cFos Versionen, cFos 3.81, für alle Betriebsysteme DOS, Windows
3.x, 9x/Me, Windows NT/2000 und OS/2.
Zu den Highlights der neuen Versionen zählen:
Damit ist cFos hinsichtlich Kostenkontrolle und Sicherheit, besonders
gut für die aktuellen Flatrate-Angebote optimiert. Aber auch der
minutenweise zahlende Internet-User hat jederzeit den Überblick.
Besonders vorteilhaft ist cFos für diejenigen, die neben DSL auch ISDN nutzen, da sie nur noch einen Treiber statt bis zu drei installieren müssen.
2. cFosConnect
ist eine kleine Freeware zum Download von www.cfos.de,
die bei Überlastung der Knoten unabhängig vom verwendeten Treiber
die automatische Neuwahl bis zu 100mal versucht. cFosConnect ist so entwickelt,
daß es bestehende RAS Verbindungen nutzt und der Benutzer mit minimalen
Mausklicks online gehen kann. Da cFosConnect auf DFÜ-Verbindungen
aufsetzt, kann es sowohl für DSL-, ISDN- und Analog-Verbindungen
eingesetzt werden.
Ab jetzt hat man also Hilfe bei überlasteten T-Online Knoten oder
dauerbesetzten Internet-by-Call Anbietern.
Technischer Hintergrund zum Mini-Firewall:
Gerade mit
ADSL, aber auch mit ISDN zeigt unsere Erfahrung, daß man nach ca.
20 Minuten Onlinezeit die ersten "Port-Scans" von potentiellen
Angreifern auf den lokalen Rechner, selbst auf einer dynamisch zugewiesenen
IP-Adresse, sehen kann.
Es gibt im Internet genügend Programme, die nach potentiellen Sicherheitslöchern
auf im Internet eingeloggten PCs suchen.
Je nach
Betriebssystem gibt es unterschiedliche Sicherheitslücken. Unter
Windows 9x und NT/2000 stellen die sogenannten NetBIOS-Ports ein großes
Problem dar. Über diese NetBIOS-Ports kann ein Angreifer nicht nur
Usernamen und Rechner-Namen erfragen, sondern auch, ob der Benutzer Datei-Freigabe-Dienste
aktiviert hat. Sollte dies der Fall sein, gibt es einschlägige Programme,
die (gerade mit ADSL) in Sekundenschnelle alle typischen Passwörter
für die lokalen Verzeichnisse durchprobieren können. Die Chancen,
so Zugriff auf die Dateien zu erhalten, sind so groß, dass in Sicherheitskreisen
die NetBIOS-Ports als sogenanntes Scheunentor" betrachtet werden.
In der Stufe 1 des cFos Mini-Firewalls werden daher Zugriffe auf diese
NetBIOS-Ports gesperrt.
Ein zweites
Problem, das bei ADSL wegen der unterschiedlichen Übertragungsgeschwindungkeit
beim Upload und Download auftreten kann, sind
Denial-of-Service Angriffe. Man kann mehr Daten zum lokalen Rechner senden,
als dieser wegen der geringeren Bandbreite in Netzrichtung beantworten
kann,
und so verhindern, daß dieser die von den Telekom-Breitband-Knoten
in regelmäßigen Abständen erwarteten Echo-Request (Wakeup-Päckchen)
versendet. Die Folge ist ein Verbindungsabbruch.
cFos blockt daher alle potentiell gefährlichen ICMP Pakete.
Als zusätzliche
Sicherheitsmassnahme können alle "unteren" TCP/UDP Ports
geblockt werden. Damit kann man von außen nicht mehr auf lokal installierte
Server zugreifen, die auf den niedriegen Standard-Portnummern installiert
sind (Webserver, Telnet, etc.). In der höchsten Sicherheitsstufe
ist es sogar möglich, alle einkommenden TCP Sessions zu verbieten
und nur noch ausgehende zu erlauben. Dies hat aber zur Folge, dass FTP-Transfers
nur noch im "passiv mode" möglich sind, was aber mit z.B.
dem Internet Explorer kein Problem ist.
Um den Mini-Firewall zu aktivieren setzt man das Modem-Register S89. Den Standardwert dieses Registers kann man als globalen Parameter beim Laden von cFos vorgeben (-x89=...), so daß er für alle COM-Ports und cFos-Modems gilt.
Dieser cFos
Paket-Filter schützt den Anwender vor bekannten Angriffen von außen.
Der Problemkreis, dass aber z.B. heimlich auf dem lokalen PC Installierte
Trojaner Daten aktiv nach außen senden oder man verhindern möchte,
daß Mitarbeiter über diesen Rechner Firmendaten nach außen
senden möchten, wird durch dieses Konzept nicht abgedeckt.
Wer so hohe Sicherheitsanforderungen hat, sollte eine professionelle Firewall
Software installieren. Wir empfehlen in diesem Zusammenhang Zonealarm
(www.zonelabs.com).
Der cFos Mini-Firewall bietet, gerade im Hinblick auf Flatrate-Tarife, aber guten Schutz vor Angriffen von außen, ohne den Anwender mit Sicherheitsfragen und/oder Installation einer weiteren Software zu belasten. Diese zusätzliche Sicherheit bekommt der Anwender bei der Installation von cFos frei Haus mitgeliefert. cFos läßt sich aber auch im Zusammenhang mit Firewall-Software einsetzen und unterstützt daher den Gedanken an ein mehrstufiges Sicherheitskonzept.
