JDSU Releases White Paper on Session Initiation Protocol's Role in IP Multimedia Subsystem Architecture

(Business News & Technology News, 25 Oct 2007)

Based on well-established IP and network infrastructure expertise, members of JDSU's chief technology office, in collaboration with the University of New Hampshire InterOperability Lab, has launched a new white paper called "IMS Simplified: The Evolution of the SIP Client." Lead authors are 22-year IP-industry veteran Jay Stewart, JDSU's director of IMS strategy; Barry Constantine, principal engineer for JDSU; and Lincoln Lavoie, senior engineer, University of New Hampshire InterOperability Lab.

The white paper provides a detailed look at the session initiation protocol (SIP) and the role it plays in delivering reliable service over the IP multimedia subsystem (IMS) architecture. It offers an in-depth analysis of the interplay between SIP and IMS to help readers realize the potential of IMS as the most significant platform for next generation networks.

"IMS is at the heart of an immense debate influencing the future of next generation network service platforms—it seemed natural to publish a paper that gets to the heart of IMS itself, the SIP client, and help clarify the role, impact and significance of these two critical client applications," said Stewart. "Simplifying IMS, JDSU's white paper examines the standards, protocols and flexibility between SIP and IMS, providing readers key insight to help utilize the platform to its fullest."

Published jointly by JDSU and the University of New Hampshire InterOperability Lab, chapters of "IMS Simplified: The Evolution of the SIP Client" focus on:
- Standards bodies that drive IMS
Includes ITU, IMT-2000, 3GPP/3GPP2, R5/R6, IETF, CableLabs, ETSI, TISPAN, ATIS, SIPPINGS, OMA
- Fundamentals of SIP
Elements and session flow, message format
- IMS Basics
IMS network groundwork, examples of IMS call flows
- SIP Clients for IMS
SIP extensions, security, signaling compression, ENUM, NAT traversal, IPv6 support

Co-authors Jay Stewart and Lincoln Lavoie are taking part in Fall VON's 2007 IMS panel, "Putting IMS Interoperability to the Test," on Thursday, November 1, 2007, 9:00am - 10:15am.
