Routing Multiple Traffic Matrices on an IP/MPLS Network

Internet Service Providers wish to optimise the usage of their IP/MPLS network and minimise the congestion caused by traffic demands exceeding the capacity of specific links in their network. When they have at hand multiple future scenarios or predictions of the traffic matrices in their network, in the current state of the art we either reconfigure the weight setting for each individual traffi...

Multiobjective Optimization for Multicast Transmissions on IP/MPLS Networks with an Optical GMPLS Backbone

Different optimization models presented on literature show optimization schemes over MPLS or GMPLS networks. However, it has not been showed models that optimize one or more parameters integrating these two types of networks. In this paper a multiobjective scheme for multicast transmissions from a source node to a set of destination nodes in MPLS passing through a GMPLS optical backbone is show...

OPNET Simulation of SIP Based IP Telephony over MPLS Network

The next generation communication system will provide high quality multimedia service in a more flexible and intelligent manner. In this paper, we propose a new SIP over MPLS network architecture to achieve this goal. To integrate SIP protocol with the traffic engineering function of MPLS network seamlessly and facilitate SIP call setup, the SIP-MPLS traffic aggregation server (TA server) is hi...

Implementation of Traffic Engineering and Addressing QoS in MPLS VPN Based IP Backbone

With increasing popularity and ever emerging business needs there was an immense focus to improve the Internet world and to provide guarantee for service delivery. Simplest example for this case is VoIP where two subscribers make a voice call through MPLS based backbone. The end subscribers should have similar quality as that of POTS. Subscribers will expect a real time conversation with limite...
