WebMux
From Wikipedia, the free encyclopedia
WebMux is a network device manufactured by CAI Networks. Its function is to direct network packets based on OSI layer 2, 3, 4, 5, and 7 protocols to multiple network servers, accomplishing both fault tolerance and high availability in hosting websites and web-based applications.
WebMux has a built-in health-checking function that detects any failure of the related network devices, including the front network gateway, using protocols like HTTP GET, or SMTP, DNS, NTP. WebMux has BAM and MAP features to relieve congestion from a single network device.
WebMux also has an SSL acceleration feature as well as features to direct website visitors based on MIME headers,cookie, and URL layer 7 pattern match. In 2006, White House took notice of CAI Networks readiness for IPV6. WebMux now supports IPV4 and IPV6 (IPV6 support in WebMux firmware version 8.2.01 and above).
A special WebMux mode called transparent makes TCP/iP and UDP/IP services communicate through WebMux as if they were communicating just via a wire. However, in HA and transparent mode, WebMux is required to use switches supporting Spanning Tree Protocol.
