摘　　要：Rollback is a synchronization mechanism in optimistic parallel discrete event simulation （PDES）. A basic and popular realization of rollback is based on cancellation of error executed messages. In this paper, several cancellation strategies are introduced, and a new method proposed. Performance comparison is made based on experimental results.Rollback is a synchronization mechanism in optimistic parallel discrete event simulation （PDES）.
