Claim One:
1. A method for performing dual-ended synthetic loss measurements, comprising: maintaining, at a local maintenance point, a transmitting session number for a first interface component associated with the local maintenance point and a receiving session number for a second interface component associated with a remote maintenance point; receiving, at the first interface component, a first one-way synthetic loss (1SL) frame from the second interface component, wherein the first 1SL frame includes a first session number indicative of the second interface component; responsive to receiving the first 1SL frame, incrementing an incoming frame count at the local maintenance point, wherein the incoming frame count is indicative of a number of 1SL frames received at the local maintenance point; when the first session number does not equal the receiving session number, copying the first session number to the receiving session number; responsive to detecting deactivation of the first interface component and activation of a third interface component associated with the local maintenance point, wherein the third interface component replaces the first interface component: assigning a second session number to the third interface component; and assigning a third session number to the first interface component, wherein the second session number and the third session number are different from the transmitting session number.
