Download Handbook on Session Initiation Protocol: Networked by Radhika Ranjan Roy PDF

By Radhika Ranjan Roy

Session Initiation Protocol (SIP), standardized through the net Engineering activity strength (IETF), has emulated the simplicity of the protocol structure of hypertext move protocol (HTTP) and is being popularized for VoIP over the web end result of the ease with which it may be meshed with internet companies. notwithstanding, it's tough to grasp precisely what percentage requests for reviews (RFCs) were released over the past twenty years with reference to SIP or how these RFCs are interrelated.

Handbook on consultation Initiation Protocol: Networked Multimedia Communications for IP Telephony solves that challenge. it's the first ebook to place jointly all SIP-related RFCs, with their needed and not obligatory texts, in a chronological and systematic manner in order that it may be used as a unmarried super-SIP RFC with a nearly one-to-one integrity from commencing to finish, permitting you to determine the massive photograph of SIP for the fundamental SIP functionalities. it's a ebook that community designers, software program builders, product brands, implementers, interoperability testers, pros, professors, and researchers will locate to be very useful.

The textual content of every RFC from the IETF has been reviewed via all individuals of a given operating workforce made from world-renowned specialists, and a coarse consensus made on which components of the drafts have to be obligatory and non-compulsory, together with no matter if an RFC has to be criteria music, Informational, or Experimental. Texts, ABNF syntaxes, figures, tables, and references are integrated of their unique shape. All RFCs, besides their authors, are supplied as references. The ebook is geared up into twenty chapters in response to the main functionalities, beneficial properties, and services of SIP.
