An improved MPLS-MOB for reducing packet loss in NGN

Abstract

We propose an improved MPLS-MOB scheme for seamless service in Next Generation Network (NGN). The existing MPLS-MOB scheme delivers signaling messages by using L2.5 switching via MPLS LSP for low handover latency. However, the MPLS-MOB scheme does not consider a solution to prevent packet loss during handover. The proposed scheme reduces packet loss by adding some process before and after connecting to new location on the existing MPLS-MOB. So, it can overcome problems from existing schemes, such as MIPv6, FMIPv6 and the existing MPLS-MOB. We analyze each scheme numerically and verify that the proposed scheme has better performance than others on handover latency and packet loss. © 2011 Springer-Verlag.
