摘　　要：线程算法是MPLSOverATM单播中最可行的网络环路预防机制,它相对于其它算法,更能够有力地支持标签合并机制,扩展性更好。详细分析了线程算法的线程控制块,并用FSM来实现线程算法控制,作出了FSM的状态转移图(SDL),最后探讨了线程算法的应用。The threads mechanism can be used to prevent Multiprotocol Label Switching (MPLS) from setting up Label Switched Path(LSPs) which have loops. It works if some, all, or none of the LSRs in the LSR support VC merge. The threads mechanism is more scalable and robust than other alternatives. In this paper, a thread control block(TCB) is analysed ,the finite state machine and the SDL of TCB is introduced. Finally the applicability of the algorithm and its advantage are analysed.
