A Simulation Study of Optimal Bandwidth Utilization for VBR MPEG-4 Streaming over MPLS-Networks

To implement the ATM architecture over IP networks, MPLS was introduced. MPLS is a recent network technology that transmits traffic effectively and supports QoS on the Internet [1]. Some researcher worked on MPEG-4 and video streaming over the MPLS networks [1] and [8] respectively. [1] proposed a new architecture based on CR-LDP for MPEG-4 video streaming. It also concludes that it is necessary to have an optimal design of bandwidth reservation in core LSRs for edge LSR. It proposes “Actively Reserved Bandwidth Architecture”. [8] performed simulations for video streaming by allocating the bandwidth for the maximum frame size. It does not provide any optimal strategy for the allocation of bandwidth.
