Abstract

The paper continues our research concerning the Next Generation Network (NGN), which is standardized for delivering multimedia services with strict quality and includes elements of the IP Multimedia Subsystem (IMS). A design algorithm for a multidomain IMS/NGN service stratum is proposed, which calculates the necessary CSCF servers CPU message processing times and link bandwidths with respect to the given maximum values of mean call set-up delays E(CSD) and mean call disengagement delays E(CDD) for all types of successful call scenarios. These delays are standardized call processing performance parameters, which are very important for satisfaction of users and overall success of the IMS/NGN concept. In the paper a block diagram of the algorithm and details regarding its operation are described. Using the implemented algorithm several multidomain IMS/NGN service stratum designs are performed for different data sets and their results are discussed.
