1. AJC - End To End Ethernet Ethernet Private Line (EPL) – Test Results September 2009

2. AJC GigE Ethernet Private Line (EPL) Tests  EPL Background  Test Configuration  RFC 2544 Tests of nominal frame sizes (Throughput, Latency, Frame Loss, Back to Back Frames, Recovery tests for 64, 128, 512, 1024, 1218 & 1518 Bytes)  RFC 2544 Tests of Jumbo Frames (9224 Bytes)  Incremental VC4’s (VC4-Nv where N = 1 to 7)

3. 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.

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

5. 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.

6. 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.

7. Throughput Granularity (VC4’s)  GigE on SDH = VC4-nV meaning 1 to 7 virtually concatenated VC4’s. Increasing throughput visible in results below/next page VC4 =1 VC4 = 2 VC4 = 3 VC4 = 4

8. Throughput Granularity (VC4’s)  GigE on SDH = VC4-nV meaning 1 to 7 virtually concatenated VC4’s. Increasing throughput visible in results below/previous page VC4 = 5 VC4=6 VC4 = 7
