A METHOD DEVICE AND SYSTEM OF REALIZING QOS (QUALITY OF SERVICE) GUARANTEE IN MPLS NETWORK

摘要

The present invention provides a method of realizing QoS guarantee in MPLS network, a method of establishing, finishing QoS data transmission and the edge router for MPLS network, the MPLS network of realizing QoS guarantee. Said method of realizing QoS guarantee in the MPLS network includes: creating the QoS resource list in each edge router, recording the resource status corresponding to the path; said each edge router assigning the resource to the requesting users according to the said QoS resource list, and updating the QoS resource list accordingly.
