APPARATUS AND METHOD FOR DYNAMIC TRAFFIC MANAGEMENT OF QOS TO AN EACH SERVICE IN HOMENETWORK ENVIRONMENT

摘要

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.
