Abstract:
1. A method of determining frame loss between two management points in an Ethernet network, in which said management points each transmit frames to each other and each of said two management points transmits to the other, in regular intervals of less than one second, measurement messages which contain current counts of frames transmitted and received by the respective transmitting management point, and in which at least one of said two management points responds to a received measurement message to compute, from counts of actual packets transmitted and/or received by a given one of the management points, the frame loss at said given management point, wherein said at least one of the management points computes said frame loss only once in a measurement interval, which consists of a multiplicity of said regular intervals, and employs in the computation the counts indicated by the measurement message most recently received by said one of the management points.
