Abstract :
In the paper we present a parallel parser for the Session Initiation Protocol (SIP), a protocol used in the 3GPP´s IP Multimedia System (IMS) framework. The parser utilizes multiple cores of a multicore processor and is based on SIP´s official Augmented Backus Naur Form (ABNF) grammar that specifies SIP´s lexical and syntactic properties. We describe in detail the parser´s algorithm, which is not bound to any programming language, and its implementations in three multicore-oriented programming languages (C++ with CILK multicore library, Java with JSR-166 multicore library and Erlang). The parser´s implementations are tested with official SIP Torture suite of messages. We show the results and discuss the strengths and weaknesses of each of the implementations.
