GMPLS-based micro-mobility for next-generation mobile broadband IP networks

Generalized multi-protocol label switching (GMPLS), which supports all types of switching, can provide next-generation mobile broadband IP networks with quality of service (QoS) and traffic engineering (TE). Future core network of wireless mobile system will be the GMPLS-based wired IP network; GMPLS must provide an efficient scheme to support micro-mobility in wireless environment. The purpose of this paper is to propose a scheme of integrating GMPLS with micro-mobility for the next-generation mobile broadband IP networks. The proposed scheme can re-establish a label switched path (LSP) rapidly when a mobile node (MN) enters a new subnet. Therefore, low latency performance can be achieved. The resource utilization in GMPLS networks can also be improved.
