With the explosive growth of Internet,the low efficiency of BGP has seriously in-fluenced its usability. In this work,a TLP(thread level parallelism) approach with local speculation is proposed to improve the BGP performance. The thread parti-tion is locally performed on each separated sub-module at route processing,and the speculation strategy is implemented to guarantee the memory consistency and sequential commit. Experiments on Intel Quad-core server show that this approach reaches an average speedup of 1.46 under single peer,multi-peers and route flap-ping. It is also shown that the packet throughput can be improved greatly under multiple sessions by taking advantage of TLP.
