Performance Analysis and Optimization of TML in ForCES Router

In order to improve the communication efficiency of ForCES transport mapping layer (ForCES TML), the paper proposes an evaluation model based on communication model of TML. In the model ,it tries to separate the communication process into two different stages: connection-setup and data-transmission stage. In both of them, we analysis the performance factors and tries to calculate the main variables which consume system resource. Also combined with the analysis , we explore several interesting factors caused by the constrains and propose methods for generating optimal solution to communication efficiency. Simulation results show the effectiveness of the improvement.
