METHOD FOR QOS DATA TRANSFERRING TRACE OF NODE-TO-NODE AND APPARATUS THEREOF

摘要

A method for supplying an end-to-end QoS(Quality of Service) data transmission path and a device therefor are provided to enable data transmission through an end-to-end QoS path, and to be applied to all routers which ensure end-to-end QoS regardless of a type of QoS routing algorithm. An ingress node within a transmission network calculates a QoS path corresponding to a QoS parameter, and generates a VLAN(Virtual Local Area Network) ID(100). The calculated QoS path is mapped with a VLAN(110). The ingress node searches the VLAN ID according to information which distinguishes an inputted path corresponding to data inputted from a subscriber(120). An egress node within the transmission network reads the VLAN ID, and searches a correspondent destination address to send data to the destination(130).
