Method of administration and maintenance of operations (AM) based on multi protocol label switching (MPLS)And device management and maintenance of operations (AM) based on multi protocol label switching (MPLS)

摘要

An OAM method based on MPLS is described, and the method includes that: after starting and executing a selected IP OAM function, a PE in a L2VPN forms an IP OAM message by using a source IP address, a target IP address and the selected OAM function and sends the IP OAM message to a PE at a receiving end; after receiving the IP OAM message and determining that the IP OAM message needs processing by itself, the PE at the receiving end performs a processing according to contents corresponding to the OAM function in the IP OAM message. An OAM device based on MPLS is also described. By using the OAM method and device, end-to-end OAM can be completed at a time to monitor services conveniently and rapidly.
