摘　　要：在网络规模和复杂性不断增加的背景下,确保网络的可靠性和高效性成为网络工程师面临的重要挑战。文中提出了一种多点双向转发检测(M-BFD)的链路检测方案,其可用于组播标签分发协议(mLDP)场景。该方案利用M-BFD实现快速链路倒换,能够提高网络可靠性和恢复性。实验结果表明,M-BFD能够准确检测链路故障,并在故障发生时快速进行倒换,减少网络中断时间。M-BFD比传统BFD具有更快的故障检测能力和更低的资源占用率。该方案在解决复杂业务环境下创建过多BFD会话的问题上具有重要意义,提高了链路检测速度和网络可靠性。In the context of increasing network scale and complexity,ensuring the reliability and efficiency of the network has become an important challenge for Network engineer.This article proposes a link detection scheme for Multipoint Bidirectional Forwarding Detection(M-BFD),which can be used in multicast Label Distribution Protocol(mLDP)scenarios.This scheme utilizes M-BFD to achieve fast link switching,improving network reliability and recoverability.The experiment results show that M-BFD can accurately detect link faults and quickly switch when faults occur,reducing network interruption time.M-BFD has faster fault detection capability and lower resource utilization compared to traditional BFD.This solution is of great significance in solving the problem of creating too many BFD sessions in complex business environments,improving link detection speed and network reliability.
