Research on Signaling Mechanism Based on Convergence Network

Automatic establishment of end-to-end multi-segment pseudo-wires by communication protocols is an effective way to improve the efficiency of path establishment. In this paper, the GMPLS protocol framework is adopted, and the layered nesting method is used to build the tunnel. Based on this, the mathematical model and analysis are carried out. An improved algorithm using RSVP-TE protocol is proposed to optimize the quality of service. The algorithm extends the protocol by adding related objects to carry pseudo-line information, and uses multi-layer nested forwarding adjacent way to establish the path on the boundary nodes of the network. The performance of RSVP-TE is analyzed experimentally, and the probability density function based on delay is introduced to calculate the mean, variance and packet loss rate of delay. The results show that compared with traditional LDP, this method reduces the delay and proves its superiority.
