BALANCING FOR NORTEL APPL SWITCH

Web OS provides Layer 2 through 7 Web application, management and traffic control services that seamlessly integrate with stackable and modular Web Switch product portfolio. Web OS offers industry-leading application support and unparalleled control of Web traffic by providing advanced load balancing (server, firewall, cache, WAN gateway, Virtual Private Network, Wireless Application Protocol, Real-Time Streaming Protocol and Intrusion Detection System), application redirection, high availability, band management and security services.Global Server Load Balancing (GSLB) allows content and servers to be distributed to up to 64 sites around the world and directs client requests to the best site based on server health, proximity to the client, server weights and response times. Each Web switch monitors the health, response time and performance of other sites and exchanges this information with all other GSLB Web switches. With a global view of each site's health and performance, Alteon Web switches direct traffic to sites in proportion to their performance measurements. As a result, the best performing sites receive more user requests than other sites, in proportion to their ability to handle additional requests. This gives users consistently good response times regardless of where their requests are directed. Web OS directs users to the best site using DNS. If all servers at a GSLB site fail or are overloaded, the Web switch at the site immediately notifies its peer switches and redirects all incoming request to the best peer site using HTTP redirect or IP Proxy. This ensures no service disruption. The prefer local option causes user requests to be redirected to the same site as their DNS request - in effect, directing client requests to the site in closest proximity to their DNS server.
