More Information
Summary:Disclosed herein are a Tandem Connection Monitoring (TCM) method in an MPLS network and a data structure of a Multi-Protocol Label Switching (MPLS) OAM packet for TCM. When data are provided to users through an LSP path comprising multiple network provider in an MPLS network, the method makes it possible to independently measure LSP performance at a user level, a service provider level, and a network provider level, detect quality degradation of ingress signals by measuring performance of a preceding network, and newly measure the performance quality at the current network regardless of the performance quality of the preceding network.
