QOS GUARANTEEING HOME-SERVER/HOME-GATEWAY APPARATUS AND ITS METHOD FOR MULTICAST TRAFFIC AT THE HOMENETWORK ENVIRONMENT

摘要

A home server/home gateway apparatus having a function of guaranteeing QoS of multicast traffic service in a home network environment and its method are provided to solve a problem of the related art that a multicast-based service such as an IPTV, multi-point online games and multi-point video conference cannot be possibly performed in a home network environment. A topology management unit(223) detects and manages topology information in a home network. A QoS management unit(225) receives a request for providing a multicast stream with guaranteed QoS from a premises terminal and requests for resource reservation. A resource management unit(228) manages network resources of the home network, searches resources by referring to topology information managed by the topology management unit(223) and reserves them. A IGMP(Internet Group Management Protocol) proxy unit(222) performs multicast routing according to a group subscription request received from the premises terminal. An IGMP snooping unit(221) sets IGMP snooping information and priority information of a switch(230) according to the topology information to guarantee QoS of multicast traffic.
