JDSU's chief technology office, in collaboration with the University of New Hampshire InterOperability Lab, today launched a white paper, "IMS Simplified: The Evolution of the SIP Client." Lead authors are Jay Stewart, JDSU's director of multimedia subsystem (IMS) strategy; Barry Constantine, principal engineer for JDSU; and Lincoln Lavoie, senior engineer, University of New Hampshire InterOperability Lab. The paper is a detailed look at session initiation protocol (SIP) and its role in delivering reliable service over Internet protocol (IP) IMS architecture. It features analysis of the interplay between SIP and IMS and the potential of IMS as the most significant platform for next-generation networks, JDSU said.  Published jointly by JDSU and the University of New Hampshire InterOperability Lab, it focuses on standards bodies that drive IMS,  fundamentals of SIP, IMS basics,  and SIP clients for IMS.  Stewart and co-author Lincoln Lavoie will participate in an IMS panel, "Putting IMS Interoperability to the Test," during the VON Fall 2007 IP Communications Conference (Oct. 29-Nov.1, Boston Convention and Exhibition Center) on Nov. 1 from 9 to 10:15 a.m. JDSU will exhibit at booth #454. JDSU is a provider of test and measurement and optical products for telecommunications service providers, cable operators and network equipment manufacturers.
