LSP blocking rate performance analysis of link state update policies for GMPLS enabled Optical Networks

With the ever increasing growth of services and the corresponding demand for Quality of Service requirements that are placed on IP-based networks, the essential aspects network planning will be critical in the coming years. A wide number of problems must be faced in order for the next generation IP networks to meet their expected performance. One of the best solutions for meeting the Next Generation Internet applications is the Optical Networks (ON´s) which has a greater potential transmission, capacity than networking in the electrical domain. The core technology in ON´s is Automatically Switched Optical Networks (ASON), which plays an important role in the dynamic routing on network connection. ASON routing protocol based on GMPLS includes the topology of optical network based on transmission of reach ability information. The Generalized Multiprotocol Label Switching is a protocol extending MPLS to manage further classes of interfaces and switching technologies. GMPLS comprises of three main protocols namely, Signaling Protocol, Routing Protocol and Link Management Protocol (LMP). In this paper, we study and analyze the performance of various GMPLS sub protocols and their corresponding performance using various LSA update policies for future betterment.
