摘　　要：介绍了基于分布式路由器体系结构,结合高可靠性网络的相关技术的LDP优雅重启技术。优雅重启机制能够在系统重启后,保持转发状态的平滑过度,从而尽量减少短暂的路由振荡。LDP优雅重启机制可最小化由于LDP重启导致MPLS网络的不稳定。最后介绍了在分布式路由器平台上实现LDP优雅重启的一种方案。This paper introduces the LDP Graceful Restart technology based on the distributed router structure, combined with some high reliability technology. Graceful restart technology can keep the forwarding state changing gracefully and minimize the negative effect on the transient routing flap after the system restarting. LDP Graceful Restart minimizes the instability of the MPLS network because of the restart of LDP. At last, a scheme to implement the LDP Graceful Restart based on the distributed router is present.
