Patent ID: 8867398

Claim:
Method of enabling a packet loss measurement in a network, the method comprising: receiving at a group of user ports data packets containing a same source address and a same destination address; performing a link aggregation of said group of user ports, by, at each user port of said group, adding to each data packet received at a respective user port an internal header element indicating said respective user port and a same network port, and, at a switching device, switching said received data packets from said user ports to said same network port using the added internal header elements; at said network port, transmitting said data packets to a far end network edge node, and determining a number of said transmitted data packets; determining for each of said user ports a respective number of data packets lost internally during the transmission from the respective user port to said network port using said added internal header elements; determining a corrected number of transmitted data packets using said determined numbers of data packets lost internally during the transmission from the respective user port to said network port, wherein said corrected number of transmitted data packets is the sum of the determined number of said transmitted data packets and an overall number data packets lost internally during the transmission from said user ports to said network port; and indicating at said network port said corrected number of transmitted data packets to said far end network edge node.
