Session setup delay estimation methods for IMS-based IPTV services

This paper proposes an IMS architecture for delivering IPTV services like Content on Demand and analytical methods of signaling delay estimation. Three methods of session setup delay estimation are proposed - the multiclass BCMP queueing networks method, the method based on homogeneous queueing networks with given variation coefficients for the probability distribution of service time, and the method with regard for background traffic. A numerical example for initial data of Iskratel SI3000 Multi Service Control Plane is provided. In conclusion advantages and area of application for the methods are discussed. © 2014 Springer International Publishing
