摘要：The Session Initiation Protocol (SIP) was devel-oped to control multi-media sessions on the Internet. Shortlyafter its debut as a standard in 1999, SIP was adoptedby the 3rd Generation Partnership Project (3GPP) as thepreferred signaling protocol for the Internet MultimediaSubsystem (IMS). This adoption provided a boost to thenascent protocol as traditional telecommunication serviceswere interpreted in the context of the new protocol andas SIP introduced richer services in the form of instantmessaging and rich presence to traditional telephony. Inthis paper, we study the evolution of the protocol from itsroots to its use in operational networks today and the issuesit faces in such networks. We also provide a glimpse to thecontinued progression of SIP in Peer-to-Peer (P2P) networksand take a critical look at where SIP has succeeded, andmore importantly, where it has failed to meet expectations.
