A New Preemption Policy for Minimizing Path Preemption Cost in MPLS Networks
Mingying Zhu, Yu Xing, Junjun Hu, Ye Wu, Suili Feng · 2010
In this paper, a new preemption policy based on LSP setup path is proposed to minimize the preemption cost. The preemption policy includes four criteria: the priority of preempted LSPs, the number of preempted LSPs, the bandwidth of preempted LSPs and the preemption degree of preempted LSPs. With the simulation, it is obvious that our policy can assure the lesser preemption cost on a new LSP's setup path.
