Abstract:
1. An Ethernet method, comprising: receiving a request to initiate an Ethernet Operations, Administration, and Maintenance (OAM) session for Ethernet Frame Loss Measurement at a local device; setting up the OAM session at the local device responsive to the request; transmitting a Protocol Data Unit (PDU) from the local device to a remote device with information related to the OAM session and the request; and receiving the PDU at the remote device and in response setting up a corresponding OAM session at the remote device based on the information in the PDU, wherein the remote device is triggered to perform local counter measurements for the Ethernet Frame Loss Measurement based on the information in the PDU, and wherein the PDU comprises a first measurement from the local device to the remote device that is discarded by the remote device for measurement purposes since it is used to set up the corresponding OAM session; initiating the OAM session and the corresponding OAM session through one of an operator issued command and an application only at the local device without requiring operator involvement at the remote device, wherein local counter measurement data from both the local device and the remote device is obtained without requiring operator involvement at the remote device to set up the corresponding OAM session; collecting frame counters at each of the local device and the remote device only while the OAM session is active; exchanging information comprising the frame counters between the local device and the remote device in counter fields in one of a Continuity Check Message (CCM), a Loss Measurement Message (LMM), and Loss Measurement Reply (LMR) and exchanging provisioning information related to duration, frequency, and configuration data in at least one Type-Length-Value (TLV) field of the PDU, wherein the Ethernet Frame Loss Measurement is single-ended, wherein the PDU comprises a LMM with local frame counter data contained therein; receiving the LMM at the remote device and programming an Ethernet Frame Loss Measurement engine to commence collection of per frame counters from the local device and composing a LMR to the local device and providing data from the collection in the LMR; and receiving the LMR at the local device and computing frame loss based on the data from the collection in the LMR.
