Here is the TrafficSqueezer - mainstream updated feature list:

Popis funkce	Podporované/není podporovaná	komentáře
Podporovaných režimů Device Configuration
Routing Mode		Traffic Squeezer engines are hooked to Linux Kernel network -> IPv4, IPv6 routing APIs. So it supports routing mode.
Transparent Bridging Mode (Layer2 L2 Bridging)		Traffic Squeezer engines are hooked to Linux Kernel network -> bridge APIs. So it supports layer2 L2 bridging/Switching mode.
Místní zařízení a nebo místní Server Optimalizace		Traffic Squeezer engines are hooked to Linux Kernel network -> IPv4, IPv6 local device packet RX, and TX flows and APIs. So it supports directly local device or local server optimization.

Release - Beta [Sep-2010 - Feb-2011]

Traffic Squeezer - BETA is released and you can download the same.

Release - Pre-Beta (Prototype Version) - [Jun-2010 - Sep-2010]
This release is far more stable than the old releases. As well it incorporates a light-weight Application and refined TrafficSqueezer Kernel Core. It has also been provided with a integrated light-weight loosely-coupled new Device GUI.

This new Device GUI is suitable for both standalone installations such as Home users/SOHO/Corporate users. And even scalable for large Network service providers too. For more details about the new Device GUI please refer the section "Traffic Squeezer - Control/Configuration Interfaces" of the Documentation.

The Traffic Squeezer - PRE-BETA feature list is removed, since now there is new Traffic Squeezer - mainstream series is available. Updated: 12-Jul-2011.

Traffic Squeezer - Big Picture

TrafficSqueezer have been made or designed to remain highly modular. WAN Optimization the more we discover, we can find its highly creative and yet no single/major technique cannot be much standardized.

Hence to achieve optimization sometimes we need to write specific optimization techniques, or else at least we should bring some existing third-party open-source modules under one roof. Linux Kernel already have some open-source modules (mostly they exist for NON-wan-optimization context), TrafficSqueezer can make use of them in the WAN Optimization Context, in the Traffic Squeezer Context and so vice versa.

Performance/latency vs Data Optimization:
TrafficSqueezer delivers reasonable packet delivery rates, which is more adequate for a reasonable WAN/Leased-Link existing services. CPU/Mother-board/RAM speeds are keep improving, for WAN or any moderate speed network-links, we are now at a point that we can do huge data-processing via TrafficSqueezer on any basic high-end system.

Kernel vs User-space:
One can recollect for example IPSec is all Kernel solution, vs. OpenVPN is all User-space solution. Both have its own advantages and disadvantages.

TrafficSqueezer zpočátku asi tři roky zpátky si myslel, že to jádro řešení, zatímco pre-alfa je postaven tak, vyzkoušet některé možnosti / prototypování v období 2006-2007 ve všech uživatelském prostoru režimu. Později Alpha je první skutečný TrafficSqueezer v prostoru jádra, zatímco pre-beta zatím ještě všechny jádra řešení, ale brzy se pre-beta by měla dostat hybridní režim, znamená, optimalizačních modulů by měly být k dispozici v prostoru jádra, měla by být k dispozici v uživatelském prostoru. K dispozici může být i případy, kdy jsou některé velmi důležité jádro by mělo optimalizace modulů se podporována jak v jádře, stejně jako v uživatelském prostoru. Důvodem pro tento návrh je divné, že na základě požadavků, v závislosti na čase, vs Hardware vs Use-případech by uživatelé dostanou větší volnost ve výběru ten, který je pro ně nejvhodnější.

So this unique architecture is shown in the picture below:

Traffic Squeezer - Alpha, Beta
Toto je skutečná výroba vydání očekává, že poskytne úplný soubor technologií, optimalizace WAN je popsáno v dokumentaci. Jádro Dopravní Squeezer dopravní optimalizaci funkčnosti by být provedeno v prostoru jádra. To by jistě lepší výkon. In-Pro konfiguraci stejně by uživatelského prostoru konfigurační utility být. Tato tisková zpráva může mít dvě varianty jednoho jízdního Squeezer, který funguje jako Layer-2 Bridge a další práci a zcela podporuje Layer-3 na bázi IP sítě směrování a může spolupracují v IP síti směrován.Runtime statistiky dopravních Squeezer, může konfiguraci a řízení stejného být dosaženo v uživatelském prostoru aplikace. Tato userspace aplikace poskytuje i rozhraní příkazové řádky (CLI) a grafickým uživatelským rozhraním webové konfigurační rozhraní. V budoucnu by měl rovněž podporovat dálkové konfigurace přes telnet a ssh sezení.

The final Traffic Squeezer architecture is expected to provide a complete FLEXIBLE and MODULAR solution to the end-user, abstracting completely low-level functional operation details. So, this includes a unified look and feel Traffic Squeezer Application and a Traffic Squeezer Kernel Level Framework.

Application Objectives:
* Allows users to configure Traffic Squeezer (both GUI/CLI based)
* Show the runtime statistics of the same (both GUI/CLI based)
* Show graph of the periodic runtime statistics samples (only GUI)

Framework Objectives:
* Any layer of PDU compression (L2 Payload, Transport Layer Payload or Complete frame,refer Traffic Squeezer Documentation)
* Any software compression algorithm(s) can be plugged
* Software Level Compression (Kernel Space) or Hardware Level Compression (Refer figure below)
* Support any third-party compression hardware accelerator cards (Refer figure below)
* Any Physical Layer Network and its corresponding Data Link Layer

Traffic Optimization in Hardware
The kernel space Traffic Squeezer in future can have a facility of a platform to which any custom Traffic Optimization can be done through any custom hardware. This is expected to make possible with the pluggable driver interface within the Traffic Squeezer Framework.

Whereas, to perform traffic data processing in hardware, a dedicated third-party hardware accelerator card performs the same job. Controlling/configuring the same can be achieved with the existing Traffic Squeezer standard user-space interface.

Release - Pre-Alpha (Prototype Version)
The prototype version of the Traffic Squeezer is the first primitive version/stage to test some capabilities which is provided by Traffic Squeezer. It supports the functionality in the user space also the data compression and frame coalescing done only on Layer-2 frame payload. The objective Traffic Squeezer software is to provide users a better way of creating a compressed and optimized data communication tunnel between two peers through which the L2 frame payload gets compressed. These features are showcased in the Traffic Squeezer first Pre-Alpha version. However this version is still a demo version, the actual Traffic Squeezer usable software would be released from Traffic Squeezer Apha and subsequent Beta versions. Refer Documentation for details.
