| Abstract: | This paper begins with a discussion of MPLS (Multiprotocol Label Switching) protocol reference model and describes the importance and functionality of OAM (Operation And Maintenance) for MPLS networks. Then it introduces the OAM mechanism and packet type based on further study of the ITU-T draft recommendation Y.1710 and Y.1711. Finally, it explains the implementation model, internal and external interface of OAM software in integrated switch and introduces in detail the functional implementation of four main modules of OAM software such as maintenance control module, connectivity management module, fault management module and performance management module. |
