SWsoft announces release of xLswitch

Author: JT Smith

SWsoft, an advanced server and networking software technology company, today announced the release of xLswitch, a traffic and content switching software product optimizing the performance and availability of Internet servers. xLswitch is a flexible, highly available and high-performance solution for service providers, e-commerce businesses and corporate enterprises that want to ensure uninterrupted, optimized and personalized service delivery to their customers.

xLswitch goes beyond simple load balancing and server health monitoring. Unlike competitors, which stop parsing IP packets at their headers, xLswitch can inspect the application-level protocols, looking for URLs, user names, cookies, etc., and redirect traffic or change the session quality-of-service parameters based on the requested content. XLswitch combines core high-performance traffic management with extensive capabilities for bandwidth management.

xLswitch is supplied with graphical multiplatform management tools, allowing easy creation of complex configurations, including load balancing, content redirection, traffic shaping and prioritization, and failover capabilities.

Reaching the highest performance levels in its class was achieved by moving most of the code into the operating system kernel and utilizing innovative algorithms for TCP-splicing and other operations. Its modular architecture allows customers to extend xLswitch with new protocol support.

The xLswitch's highly capable development team, lead by Alexey Kuznetsov (one of the maintainers of the Linux kernel), is ready to undertake the most challenging projects that are based on xLswitch.

"xLswitch was designed to be easily extendable from the very beginning. You can add a module to support new application protocols, and you can add controls for it in the GUI tools," said Alexey Kuznetsov. "We supply SDK and documentation for developers, and there a lot of people who would like to customize their setup, and, most importantly, who are knowledgeable enough about Linux.", one of Europe's largest fashion Web sites, experienced substantial decreases in downtime and better site performance when engineers integrated a customized xLswitch solution. "Our site is highly graphical and has a lot of dynamic content. These things usually don't mix well," said Anatole Orehovsky, IT Manager, "We noticed significant increases in site performance and reduced server load with the implementation of the xLswitch software."

Pricing and availability

xLswitch is available immediately. Promotional prices are in effect for the first two months, making xLswitch up to 50% cheaper than competitive products.
