Ethernet Private Line (EPL) Background

The diagram below is an extract from ITU-T Rec G.8011.1 (01/2009) “Ethernet Private Line Service”. AJC EPL is point to point fixed bandwidth consistent with relevant recommendations. AJC EPL is provided from AJC cable station to AJC cable station (UNI-N below) and AJC can also arrange the access.

GigE EPL tests have been done Aust.-Japan (AJC) and Aust.-US West Coast (AJC & Pacific Crossing) using the setup below.

Ethernet Test Procedures - RFC 2544

Some of the results obtained for nominal frames are below.

Padd ington to Shima: Frame Loss = ((Tx-Rx)/Tx) = zero for Throughput up to 99.99% for the nominal byte sizes.

Paddington to Shima – Throughput bytes/sec increase at expected rate as frame size increases given the 20 byte overhead percentage is less.

RFC 2544 - Jumbo Frames (9244 Bytes)

RFC 2544 describes test procedures for Ethernet. Some of the results obtained for Jumbo frame are below.

Paddington to Shima – Throughput frames/sec near 100% as expect for 9224 byte frame as 20 byte overhead a small percentage.

Paddington to Shima: Frame Loss = ((Tx-Rx)/Tx) = zero for Throughput up to 99.99% for the single 9224 byte size.
