The goal of the SIP Performance and Benchmarking project was to create a standard method to compare the performance of SIP proxies and B2BUAs. Lacking a common definition of terms it was not possible to judge which implementation of a proxy would best meet the requirements of a given use case. A definition of "performanance" was created and a method for testing it was proposed. Students built a testbed on which the performance of several proxies was measured using the methodology described. A conference paper descibing results, "Benchmarking the session initiation protocol (SIP)", was published in the IEEE XPlore digital repository. Two IETF RFC's, RFC 7501 and RFC 7502, that describe the terminology and methodology were published in 2015.
