Abstract: A dynamic traffic management device for ensuring QoS(Quality of Service) for each service in a home network environment and a method therefor are provided to dynamically control the amount of bandwidths used by best-effort traffic in the home network environment associated with the Internet on the basis of a home server/home gateway, thereby ensuring QoS for a particular service. A resource manager(211) manages available network resources and traffic processed in a home network environment, and generates QoS lists(215) which refer to packet information of services to be ensured. A traffic controller(212) performs a traffic control function by searching traffic flows of currently serviced best-effort services until bandwidths are obtained as many as being requested. A traffic classifier(214) searches all packets inputted/outputted to the home network environment, and decides whether the packets correspond to the QoS lists(215). A traffic marker(213) marks the classified packets. A scheduler(231) supports scheduling by a predetermined method.

Abstract: 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.
