Paper Abstract

Because SONET/SDH technology which includes contiguous concatenation and virtual concatenation is used in GMPLS-Controlled Multi-services Transport Platform (MSTP) Network, it is more complex when we consider the label assignment when setting up a Label Switch Path (LSP). It is very imperative to use a method which could use the limited labels effectively. In this paper, we study the structure of the label space and different label algorithm to allocate SONET/SDH labels, which include virtual concatenation labels and contiguous concatenation labels in GMPLS-Controlled MSTP Network. We proposed a minimum Contiguous Labels Algorithm (min-CLA) to solve the problem of using the limited label space on each interface at the most degree. Different from the previous schemes worked on Route Wavelength Assignment (RWA) in the Wavelength-Division-Multiplex (WDM) networks, our scheme finds out the primary and easy method based on SONET/SDH label which has virtual concatenation labels and contiguous concatenation labels used for different kinds of needs. Because of taking the multiple services requirements into account, the proposed algorithm finds out more efficient feasible solution requiring less network resources and even find a feasible solution which will enable some label assignment failed in other label assignment algorithm and we will compare our scheme and the Fist Fit Scheme.
