Although Session Description Protocol (SDP) serves quite well for point-to-point multimedia conferencing, its protocol architecture is such that it cannot be extended for distributed multipoint multimedia conference as of today. The only multipoint conferencing is the centralized star-like topology with the a priori known address of the centralized controller. In this conference architecture, capability negotiations are done using SDP in point-to-point fashion only. When we work with SDP, we have to know its limitations, namely, how and where we can use SDP for setting up multimedia conferencing dynamically. This has created a new urgency for a book on SDP, providing the full treatments due its merits. Like all other standards, you have to know exactly how many RFCs have been published or even related to the base SDP over two decades and how they are interrelated to each other after so many extensions and enhancements with new features and capabilities, corrections, and modifications with the latest agreed-upon interpretations based on implementation and interoperability test experiences, as well as future research for breaking new ground and knowing what already exists in SDR Handbook on SDP for Multimedia Session Negotiations: SIP and WebRTC IP Telephony puts all SDP-related RFCs together with their mandatory and optional texts in a chronological, systematic way so you can use a single "super-SDP RFC" with almost one-to-one integrity from beginning to end to see the big picture of SDP in addition to base SDP functionalities. The book uses text, figures, tables, and references from RFCs as much as necessary so you can use all those as they are found in the RFCs. Book jacket.
