With the migration of real-time applications such as voice onto IP-based platforms, the existing IP network capabilities become inadequate to provide the quality-of- service (QoS) levels that the end-users are accustomed to.

—In order to provide high quality multimedia service in a flexible and intelligent manner, future wired and wireless networks will employ SIP as the call control protocol and MPLS as the core network packet switching technology. In this paper, we propose a traffic aggregation based SIP over MPLS network architecture to integrate SIP protocol with the(More)

Metropolitan networks and core backbones are over provisioned and rarely represent a problem from the end user perspective. The advent of triple-play has brought new aspects to be considered, since no quality drops are desired during(More)
