摘要：
The preemption policy with three main preemption optimization criteria is proposed in many literatures and the choice of LSPs to be preempted is an NP-complete problem. We propose a heuristic algorithm called B-PREPT to solve the problem. Simulation results indicate that our algorithm has higher choice accuracy than the well-known heuristic algorithm recently cited by many other papers. Moreover, the computational complexity of our algorithm is acceptable for router's online computing in large scale networks.
