Abstract: |
The IP Multimedia
Subsystem is an architectural framework for delivering multimedia services
over an Internet Protocol (IP) network. Originally, it was specified for
wireless networks, but has since evolved to incorporate fixed line access as
well. It forms part of a Next Generation Network (NGN)
which
is defined as a packet-based network where the service functionality is
independent of the underlying transport technologies. This allows new
converged services to be implemented on top of an existing packet switched
network. the centralized conferencing framework
limits the ability to have large number of participants because of the
overhead on the server. One of the possible efficient solution
for increasing of server’s performance is grouping meeting requests the same
video conference and serving them at one time on an edge-proxy. The queuing
model with batch exhaustive service and working vacations is constructed and
analyzed. The stationary distribution and the formulas for main performance
measurements are obtained. In addition, the optimization problem for
increasing a server performance is formulated. |
