Created in 1999, request for comment (RFC) 2544 is a test and measurement methodology used to evaluate network devices. From a laboratory and benchmarking perspective, RFC 2544 methodology is ideal for automated measurement and reporting. From a service turn-up and troubleshooting perspective, RFC 2544 provides an out-of-service benchmarking methodology for evaluation of network/device performance using four subtests with up to 10 configurable frame sizes, each validating a specific portion of an SLA. RFC 2544 provides engineers and network technicians with a common language and results format.

As 400G moves from the lab to the field (the first 400G deployments are imminent), ensuring service quality at turn-up is becoming key. Portable 1G to 400G test equipment will enable field technicians and contractors to immediately capture test results and demonstrate that the Ethernet service meets SLAs. These tests may also serve as a performance baseline for future reference.

RFC 2544 includes the following subtests: throughput, back-to-back (bustability), frame loss and latency.
