Solutions and Comparison of Performance to the Key Technologies of PIM-SM under ForCES Architecture's Router

Abstract

The update of many stats and timers maintained in PIM-SM protocol relies on the current forwarding results of multicast packets on FE. There is a new challenge to the realization of the protocol in ForCES architecture router because the main body of PIM-SM is running on CE under ForCES architecture. In this paper, we analyze key technologies of PIM-SM in the ForCES architecture router, and present their possible solutions. We also implement the ForCES router test bed according to the solutions. Through the experiment results, some detailed comparison and performance analysis are finally made in this paper.
