Optimizing the MPLS support for real time IPv6-Flows using MPLS-PHS approach

The huge coverage space of IPv6 addresses and providing guaranteed support for the ever increasing customer demand, results in the dealing with bigger packet header-size compared to the payload-size especially in some real time video and audio applications, consequently more bandwidth is wasting. Using the advantages of MPLS with IPv6 is still one of the migration challenges at the backbone. Payload Header Suppression (PHS) approach is currently being used in Mobile WiMAX networks for point to point (SS to BS) communications. The proposed approach for this paper (named) MPLS-PHS adapt the concept of the PHS technique mentioned above, modified to be applicable for multihop of Label Switching Path (LSP) of MPLS domain at which multipoint-to-multipoint connection found (Ingresses to Egresses). The results clearly show a dramatic increase in the data throughput for real time IPv6 flows.
