NETWORK LINK DUPLEXING SYSTEM IN REAL-TIME TRANSPORT PROTOCOL NETWORK SYSTEM AND CONTROL METHOD THEREOF

摘要

A network link duplexing system in an RTP(Real-time Transport Protocol) network system and a control method thereof are provided to improve the performance of a router and to reduce the loss of resources without using a VRRP(Virtual Router Redundancy Protocol). A network link duplexing system in an RTP network system includes a link control unit(100), a first router(210), and a second router(220). The first and the second routers(210,220) are linked in duplex configuration to be connected to the link control unit(100). The link control unit(100) sets the first router(210) as a master and the second router(220) as a slave. When trouble occurs at the first router(210), the link control unit(100) changes settings of routers(210,220) and replaces the MAC information of the first router(210) which is registered at the RTP session Hash table with the MAC information of the second router(220).
