Systems and methods for measuring frame loss in multipoint networks

摘要

Systems and methods for measuring frame loss in multipoint networks are provided. In one embodiment, a method for calculating frame loss comprises: performing a first continuity check message exchange between a first and a plurality of other devices, the first exchange comprises the first device collecting a first set of frame count data from each of the first and other devices, the first set of frame count data associated with a first instance of time by a first sequence identifier; performing a second continuity check message exchange between the first and plurality of other devices, the second exchange comprises the first device collecting a second set of frame count data from the first other devices, the second set of frame count data associated with a second instance of time by a second sequence identifier; and calculating a frame loss measurement by accounting for frame Ingress and frame Egress.

1. A method for calculating frame loss in a multipoint network, the method comprising:
performing a first continuity check message exchange between a first network interface device coupled to the multipoint network and a plurality of other network interface devices coupled to the multipoint network, wherein the first continuity check message exchange comprises the first network interface device transmitting a first multicast continuity check message and collecting a first set of frame count data from each of the other network interface devices and the first network interface device, wherein the first set of frame count data is associated with a first instance of time by a first continuity check message sequence identifier; performing a second continuity check message exchange between the first network interface device and the plurality of other network interface devices, wherein the second continuity check message exchange comprises the first network interface device transmitting a second multicast continuity check message and collecting a second set of frame count data from each of the other network interface devices and the first network interface device, wherein the second set of frame count data is associated with a second instance of time by a second continuity check message sequence identifier; and calculating a frame loss measurement for the network by accounting for frame Ingress and frame Egress from the network based on the first set of frame count data and the second set of frame count data.
