Обычная передача данных:
Прием данных должен быть подтвержден (ACK-пакеты) прежде, чем можно будет отправить новые данные.

Без Traffic Shaping:
Передача данных задерживает ACK-пакеты. В результате скорость приема тоже снижается.

cFos Traffic Shaping:
ACK-пакеты получают высокий приоритет, позволяя принимать данные на максимальной скорости.

Приоритезация трафика (Traffic Shaping) лучше всего проявляется для

• Широкополосные соединения: DSL, Cable
• Коммутируемые соединения: modem, ISDN
• Мобильные
• Файлобмен (P2P)
• Игры
• Потоковое мультимедиа, VoIP
• Возможности
• Снижение задержек (ping)
• Приоритезация программ
• Приоритезация протоколов
• Ресурсы (Budgets) Онлайн
• Межсетевой экран (Firewall)

Каждый раз, когда вы подключаетесь к Интернет и используете более одного потока данных cFosSpeed может оптимизировать трафик.

• Улучшает ваш Ping для онлайн-игры
• Поддерживает Интернет быстрым во время интенсивной загрузки/выгрузки
• НОВОЕ : Улучшает мобильный Интернет
• Сокращает проблемы с аудио/видео интернет потоками
• Улучшает качество речи в программах использующих VoIP

What's New in This Release:

• Added support for Logitech G15 and G19 Gamer keyboards. When cFosSpeed detects such a keyboard, it offers a the option to display the status window on the display of the G15 or G19 display. If you enable it, the skin windows will then be displayed on the keyboards display, thereby offering all cFosSpeed Traffic Shaping information during fullscreen mode apps / games. In addition, you can switch between low latency / favour bandwidth wit the Button 1 on the G15 and the UP Button on the G19.
• Skins for Logitech G15 & G19 were donated by Ingo Gunther.
• Added keyboard LED indicators. cFosSpeed can indicate certain traffic shaping values by blinking the Num Lock and Scroll Lock LEDs. See http://www.cfos.de/en/cfosspeed/documentation/keyboard-leds.htm for more information.
• When the traffic class is still not set (at the beginning of a connection) the class column will display "working" or nothing. If more traffic is coming, the class name will be shown or when no rule matches and no class has yet been set for a connection the class is set to default.
• If traffic shaping is (partly) inactive, this is now shown in "spd speed" command.
• Added -udp-vol rule: it counts the volume of an UDP pseudo-connection. Volume in this sense are all bytes including the IP and UDP header. Added -udp-cnt rule: it counts the number of UDP packets in an UDP pseudo-connection.
• Extended arguments for -tcp-seq and -tcp-cnt rules to 64 bit.
• Added gset variable tx_shape, default 1, to en/disable tx-shaping globally.
• TCP SYNs were not properly prioritized. Fixed.
• Uploads do now slow down downloads less than before.
• Fixed behaviour of overlapping active areas in skins. Now the topmost one catches the mouse click.
• For troubleshooting, you can now specify the Net Talk broadcast address. Use "spd set net_talk_bcast x.x.x.x" to do that, address 0.0.0.0 means use default, which is 255.255.255.255 or the subnet broadcast address like 192.168.0.255. Thanks to Drool for inspiration.
• Fixed serious bug in -l7-prot, -udp-prog, -tcp-prog and -prog filter rules when they were used with negation (like -l7-prot !@user.ini/normalprots). This caused program and protocol settings to malfunction if you had made changes to them (changes are recorded in user.ini and filter rules contain negations to read them properly). This bug was introduced in since v5.13.1694. Thanks to km for his bug reports.
• The installer started the status window with elevation. Fixed.
• Fixed installation problems where cfosspeed.exe could not be overwritten.
• Fixed a potential problem when stopping a system service. Thanks to Richard B. for testing.
• Skins would not display more than 21Mb/s speed. Fixed. Thanks to kamcm for bug report.
• Fixed a long-standing problem where cFosSpeed might perform poorly after a wakeup from standby. Notably, UDP connections would not time-out and ever increase in numbers.
• Fixed a error where certain skins would be incorrectly loaded and thus not displayed at all.
• Fixed a bug in -prog and -l7-prot filters: they did not properly accept multiple arguments separated by commas. Thanks to Thomas Quella for his bug report.
• Large ping values were always displayed as 999ms. Fixed.
• On some machines the status window was always topmost. Fixed.
• Fixed a spurious freeze. Thanks to Andrey Chernov for dump file.
• For Windows 7 the main icon is not hidden as long as at least one icon skin is displayed. Otherwise Windows cannot remember the icon settings. If you don't want to see the main icon, you can disable it in the context menu. For older OSes the main icon is hidden as long as at least one icon skin is displayed.
• Variance accommodation now works for satellite connections with their very long ping times as well. Thanks to ipcopter.de for help and support.
• No pinger boot will be done if both rx_shape and tx_shape are 0.
• Better tracking if test-pings reached the destination. If so, pinger will not be used for burst and pingstat line starts with a '+'.
• Tested cFosSpeed with "teaming". We used an Intel Gigabit ET Dual Port Server Adapter and their most recent teaming software v16.2. Please note: The route to the Internet must go through the virtual teaming adapter, not through one of the individual teamed adapters.
• Important notifications, e.g. the calibration notification and the trial period expiration messages are now indicated by a symbol in the status window if the skin supports it. Otherwise, the usual browser popup is used. If you click on the symbol the corresponding website is displayed.
• The options menu is now also available for non-admins.
• More trace output for an installation problem where the service can not be deleted.
• By default max_trace_size is now 10 mbytes.
• Switched to new compiler.
• If for some reason test-pings reach their destination (i.e. they are not returned with "TTL exceeded"), we inhibit further test-pings with that TTL.
