摘要： The present invention relates to a method and a network node for service instance management in telecommunications network. According to the method a plurality of network paths are monitored. A number of network paths form a protection group associated with a service instance or group of service instances. The monitoring of the network paths includes periodic transmission of CCMs on the network paths. To facilitate detection of mismatches related to protection switching, some CCMs include a mismatch information element that specifies traffic status of a working network path and of a protection network path for a set of protection groups. The set of protections groups includes the protection groups which the monitored network path is a member of. A CCM that includes the mismatch information element also includes an indication bit that indicates presence of the mismatch information element in the CCM.

摘要： A network interconnect node of an internal network may communicate with an external network interconnect node of an external network, other internal network interconnect node(s) and internal network node(s). The network interconnect node may receive frames from the external network interconnect node and forward them according to a Virtual Local Area Network (VLAN) tagging forwarding process to other internal network interconnect node(s) or internal network node(s) based on whether the network interconnect node is active for the service associated with the frames. The network interconnect node may receive frames from other internal network interconnect node(s) or from internal network nodes and forward them according to the VLAN tagging forwarding process to other internal network interconnect nodes, internal network nodes or the external network interconnect node based on whether the frames are encapsulated frames and/or whether the network interconnect node is active for the service.

摘要： A Maintenance Association and corresponding method for configuring maintenance entities for Ethernet Tree (E-Tree) type service instances. A root MEP communicates with each of a plurality of leaf MEPs. Remote MEP state machine instances are activated within the root MEP for each of the plurality of leaf MEPs. Within each leaf MEP, however, only the remote MEP state machine instance for the root MEP is activated while leaving the remote MEP state machine instances for all other leaf MEPs in an inactive state in which Connectivity Check Messages (CCMs) are not exchanged.
