NETWORK ASSOCIATES GRANTED NEW U.S. PATENT FOR GRID PROXY SERVERS

Newly patented technology improves efficiency in context switching and enables higher throughput of data on servers.

Network Associates Inc, a leading provider of network security and availability solutions, today announced that the United States Patent and Trademark Office has granted the company U.S. Patent number 6,510,448 for its technology invention in the field of proxy servers and context switching.

The technology described in the granted patent, entitled "System, Method And Computer Program Product For Increasing The Performance Of A Proxy Server," improves the performance of proxy servers or application-level gateways by enabling improved context switching. This is accomplished by utilizing a software 'virtual machine', a self-contained operating environment that runs separately from the operating system, or other mechanism or module.

The granted patent covers multiple systems and methods that increase efficiencies in proxy server traffic. For example, when a process or thread is blocked, the proxy server can switch to a different process or thread, also known as a context switch.

The frequent blocking of network read/write operations can result in frequent context switching, which ultimately reduces the input/output that occurs on a network. As disclosed in the granted patent, a software virtual machine or other mechanism or module can increase the efficiency of that context switching, and in an application to a networking environment, can improve the efficiency of handling input/output operations through improved control of switching between contexts.

The performance of context switching in process and thread-based proxies is an important field of research and development in the security industry because it helps to reduce cost associated with switching between contexts while increasing efficiencies in data input/output. The technology in the granted patent is useful in improving the performance of anti-virus software, firewalls, intrusion protection or detection, networking software or other technologies where optimizing speed and minimizing resource demands are important.

Furthermore, this newly granted patent is applicable to a variety of computer systems or networks including, but not limited to, firewall systems such as application-level gateways or proxy servers. "As part of Network Associates comprehensive technology portfolio, we are dedicated to the development of cutting-edge technology that monitors network perimeters, devices and traffic for potential threats, and protects against attacks or misuse which can damage critical information resources," said Ryan McGee, director of product marketing for McAfee Security at Network Associates.

"We remain committed to rapidly identifying potential threats and responding quickly to those threats by incorporating the most innovative technologies into our comprehensive line of security solutions. This newly granted patent is another example of this advanced technology that enables us to provide customers with comprehensive security and increased efficiency on their networks."

The software virtual machine can support restartable instructions on the proxy server to ensure that, when resumed, a previously blocked context will continue with the instruction that had previously been blocked or suspended. This increased efficiency reduces the overhead expense and delays associated with traditional context switching, and increases the number of transactions per second that the proxy server can handle.

With headquarters in Santa Clara, Calif, Network Associates Inc is a leading supplier of network security and availability solutions. Network Associates is comprised of three product groups: McAfee Security, delivering world-class anti-virus and security products; Sniffer Technologies, a leader in network availability and system security; and Magic Solutions, a leader in innovative service management solutions.
