Abstract:
1. A method for calculating frame loss in a multipoint network, the method comprising: synchronizing local Performance Monitoring (PM) frame count bin boundaries across at least three VLAN Endpoints of a multipoint network; receiving a first sample of frame count data at a network manager from a first local PM frame count bin from each of the at least three VLAN Endpoints on the multipoint network, wherein the first local PM frame count bin for each of the at least three VLAN Endpoints is defined by a beginning time boundary and an ending time boundary, and the first local PM frame count bin boundaries for each of the at least three VLAN Endpoints are synchronized so that their respective beginning and ending time boundaries agree; and calculating a frame loss for frames transported through the multipoint network by accounting for frame ingress and frame egress from the multipoint network through the at least three VLAN Endpoints based on the first sample of frame count data; wherein the first sample of frame count data includes a number of frames that ingress at each of the at least three VLAN Endpoints and a number of frames that egress at each of the at least three VLAN Endpoints during a first period of time defined by the local PM frame count bin boundaries.
