Differentiation of Services in IMS over MPLS Network Core
نویسندگان
چکیده
Traffic engineering and QoS Fguarantee is crucial point of any operators’ network. To evaluate IMS services over MPLS enabled network in case study, we have created a testbed for a service provider. Our service provider distributes various services requiring different traffic priorities together with customer-generated traffic. We have enabled the IMS core to trigger associations based on customer classes with specified server acting as RTP proxy for media flows. The network traffic is shaped to provide MPLS Traffic Engineering tunnels with various priorities towards these application servers in IMS core. This setup allowed us to show that IMS over MPLS network creates scalable and sustainable solution for providing adequately priced priorities together with QoS management for different customer classes based on IMS user profiles.

Traffic Engineering Algorithms Using MPLS for Service Differentiation
This paper proposes an approach to Traffic Engineering that uses Differentiated Services (diffserv) and Multi-Protocol Label Switching (MPLS) to provide quantitative QoS guarantees over an IP network. An algorithm that determines QoS-constrained routes is proposed and a framework that uses such an algorithm is outlined. This framework removes the responsibility of QoS guarantees from the core n...
متن کاملA Traffic Engineering Approach to Differentiated Multicast Services over MPLS Networks
Currently, a viable solution to provide multicast provision over a multiprotocol label switch with traffic engineering (MPLS-TE) domain is unavailable because of the missing link able to couple multicast traffic distribution with an MPLS-TE enabled network. This is due to the limited or less research investigation that was done in this area. Most of the investigation methods tackle the problem ...

MPLS networks have evolved over the last 10-15 years and have become critically important for ISPs. MPLS is primarily used in two ways: to perform traffic engineering in IP networks, providing greater determinism and more efficient usage of network resources; and for enabling MPLS based L2 or L3 enterprise Virtual Private Network (VPN) services, which continues to be one of more profitable serv...

IMS (IP Multimedia Subsystem) network is considered as an NGN (Next Generation Network) core networks by ETSI. Decomposition of IMS core network has resulted in a rapid increase of control and signaling message that makes security a required capability for IMS commercialization. The control messages are transmitted using SIP (Session Initiation Protocol) which is an application layer protocol. ...
