Packets Forwarding Based on NP in Multi-FE Environment

IETF ForCES Working Group proposes an open programmable IP router architecture which is composed of FE and CE. There are many FEs in this kind of structure router. The packets may be forwarded by non-local FE. In view of this kind of packets, this paper proposes a method of packets forward among multi-FE which independent to FE physical connection characteristics to solve FE communication problem in ForCES router. In based on NP ForCES FE, we design and implement two key modules to realize FE communication message encapsulation and decapsulation. Finally, by testing packets forward between multi- FE, we verify the correctness and feasibility of the program.
