Executive Summary

Reliable transmission of multimedia traffic requires stable network bandwidth. In reality, network bandwidth on the internet is still insufficient. As a result, multimedia- oriented applications have failed to gain popularity. The huge amount of traffic on the internet leads to congestion in routers. Hence, internet has to overcome these hurdles to provide better multimedia- oriented applications. This paper provides an answer to the above mentioned problems by proposing architecture for MPEG-4 based video traffic in the MPLS networks. It is termed as Actively Reserved Bandwidth Architecture. It improves CR-LDP in MPLS networks. The architecture has been designed to tackle the router bottleneck in MPLS networks. MPLS is a highly efficient communication network and it provides high Quality of Service (QoS). This approach is advantageous to MPEG-4-based video traffic transmission. Further, the paper studies the differences between MPLS and conventional routing. The paper conclude that treating VOP as the unit of transmission is better suited than taking one packet as the unit of transmission. The proposed architecture gives better results and is highly suitable for multimedia traffic on the internet. Traffic engineering of MPLS and Internet router for differentiation of the incoming traffic is a potential technique for future transmission requirements. It has made flow-oriented control much easier in the LSR and also supports QoS mechanisms. The paper proposes methods of transmission which are much more efficient than conventional methods.
