HIGH SPEED PLC NETWORK-ETHERNET BRIDGE SYSTEM SUPPORTING QOS

摘要

A high speed PLC-Ethernet bridge system supporting QoS is provided to supply QoS according to traffic characteristics or characteristics for an application service by solving QoS heterogeneity between two networks. A QoS(Quality of Service) controller(110) controls QoS processing of the whole bridge system. A flow manager(130) stores and manages connection information about QoS information requested for each flow and information necessary to perform a bridge function. A bridge QoS processor(140) performs allocation and management of inner resources of the bridge system and a QoS providing function by referring to the control of the QoS controller and the information stored in the flow manager. A PLC(Power Line Communication) QoS processor(150) performs QoS management function for a PLC network according to the control of the QoS controller. An Ethernet QoS processor(160) manages a link state at Ethernet and provides the management result to the QoS controller.
