![]() ![]() ![]() PBB encapsulation is available for all Ethernet tests (Layer 2,3 and 4). The linked post, although first published a few years ago, is still valid today.įancy a chat about your testing routines. Available for 1GE Copper/Fiber and 10GE port. Today we have Y.1564 - designed to verify service SLA's and validate criteria such as Latency, Frame/Packet delay variation, multiple streams to name a few criteria. In the late 90's RFC-2544 was 'invented' to test and compare network elements - it too wasn't ideal, and has many 'limitations' and can pose a risk to the network, but it was better than relying purely on BERT. Naturally BERT was the first test method of choice because it was familiar but it doesn't really cover the variables needed. Throughput, back-to-back, latency and frame loss measurements as per RFC 2544. We have to consider 'new' parameters such as frame sizes, frame rates, bursts that were not there before. standard for testing Ethernet mobile backhaul and commercial services. Then along came these 'frames' and 'packets' and the world of transmission evolved. In the 'good old days' of PDH and then SDH TDM transmission it was easy to test using a simple Bit Error Rate Test (BERT) to validate that the transmission was error free. RFC 2544 Testing of Ethernet Services in Telecom Networks White Paper Nigel Burgess Agilent Technologies. It exists at many speeds and interfaces from 10Mbps electrical all the way to 100Gbps. Whether we like it or not, in the world of Telecoms, Ethernet is now the transmission medium of choice and has become both ubiquitous and commoditized. ![]()
