Traffic Squeezer is an Open-Source Project which does provides WAN Network Traffic Acceleration solution through a set of procedures on a Linux based network device released under GNU General Public License.
WAN/Internet Optimization techniques (source: wikipedia)
- Deduplication - eliminates the transfer of redundant data across the WAN by sending references instead of the actual data. By working at the byte level, benefits are achieved across IP applications.
- Compression - Relies on data patterns that can be represented more efficiently. Best suited for point to point leased lines.
- Caching/Proxy - Relies on human behavior, accessing the same data over and over. Best suited for point to point leased lines, but also viable for Internet Connections and VPN tunnels. Effective use of web caching typically sees a bandwidth reduction of 15-30% on WAN links.
- Protocol spoofing - Bundles multiple requests from chatty applications into one. Best suited for Point to Point WAN links.
- Traffic shaping - Controls data usage based on spotting specific patterns in the data and allowing or disallowing specific traffic. Best suited for both point to point leased lines and Internet connections. May be hard to keep current with ever expanding types of applications.
- Equalizing - Makes assumptions on what needs immediate priority based on the data usage. Excellent choice for wide open unregulated Internet connections and clogged VPN tunnels.
- Connection Limits - Prevents access gridlock in routers and access points due to denial of service or peer to peer. Best suited for wide open Internet access links , can also be used on WAN links.
- Simple Rate Limits - Prevents one user from getting more than a fixed amount of data. Best suited as a stop gap first effort for a remedying a congested Internet connection or WAN link.
Traffic Squeezer does WAN Acceleration with the technologies such as Traffic Compression, Traffic PDU Coalescing, Protocol Specific Acceleration (ex: TCP Acceleration Mechanisms), Quality of Service, etc.

Snapter
There are both free and paid versions of Snapter. You can download the free version and enjoy the full functionality for the first 14 days. After that, the software is still functional, but it will add a tagline and light watermark on your images. If all you need is to convert the images to a portable version so you can read while on the move, the free version is good enough for you.
Microsoft, Researchers Team Up And Tear Down Major Spamming Botnet
Microsoft, Researchers Team Up And Tear Down Major Spamming Botnet
Unprecedented court order helped dismantle Waledac, the second-gen iteration of the Storm botnet; here's how the undercover operation went down
By Kelly Jackson Higgins
Waledac -- the spamming botnet formerly known as Storm -- was downed yesterday in a sneak attack by a team from Microsoft, Shadowserver, the University of Washington, Symantec, and a group of researchers from Germany and Austria who had first infiltrated the botnet last year.
In an unprecedented move, Microsoft secured a federal court order that, in effect, required VeriSign to cut off 277 Internet .com domains that were serving as the connections between Waledac's command and control (C&C) servers and around 60,000 to 80,000 bots or infected machines it had recruited to spew its spam. Waledac is best-known for its online pharmacy, phony products, jobs, and penny stock spam scams, and has the capacity to send more than 1.5 billion spam email messages per day.
The so-called "Operation b49" effort basically turned the tables on the Waledac botnet operators by systematically hijacking the communications between the botnet and its infected bots. Once Microsoft had the court order in hand from the U.S. District Court of Eastern Virginia in response to its legal complaint, researchers from the University of Mannheim in Germany and the Technical University of Vienna launched a massive attack on the botnet's hybrid peer-to-peer/HTTP communications infrastructure, according to one of the researchers who handled that part of the operation, but declined to be named publicly.
TechNet 2.0 Goes Live
With the launch of the new TechNet experience, I could spend this entire space on my favorite new features, but heck, just go to TechNet and check it out on your own.
Near and dear to my heart is the expanded Today's News section on the TechNet home page with constantly updated news from real people (you'll want to check this every day and subscribe to the feed).
Also notice the enhanced search with meta-data enabled search results for TechNet Forums and new finders for troubleshooting resources and downloads. You'll find a new TechCenter experience with version scoping and Bing-powered search. And the TechNet Profile user experience offers enhanced tracking of user contributions and activities. There are plenty more great improvements. See it for yourself.
