Overview
V-SAM (VeEX Service Activation Methodology) is an automated Ethernet service activation test feature conforming
to the ITU-T Y.1564 standard, created to address and solve the deficiencies of RFC 2544:
• RFC 2544 was limited to test at the maximum throughput line rate for a single service. SAM is able to
run multiple services on a single 10/100/1000 or 10G Ethernet line at a bandwidth ranging from 0 to the
line rate, allowing for more realistic stream testing
• The Frame Delay Variation, also known as (packet) jitter was not included in RFC 2544. Jitter is a
critical parameter for real time voice and video services. It is now part of the SAM test suite.
• RFC 2544 validates the service parameters like frame loss, throughput and latency, one after the other,
while SAM allows testing all the service critical parameters simultaneously. This results in significant
time saving compared to RFC 2544.
