摘　　要：MLDP协议是LDP协议的扩展协议,它对LDP协议进行扩展以满足组播的需求。在实现MLDP协议时,转发等价类FEC的处理流程是至关重要的。FEC必须被正常创建,MLDP协议才能正常工作,LSP才可能被正常建立。文章提出一种实现MLDP协议时可行的FEC的处理方案。此方案主要关注FEC创建部分流程,对FEC的删除及释放流程不予叙述。该方案可成功创建FEC,并使其正常工作。文章通过几种可能的情况来详细描述FEC的处理流程。最后通过仿真对其加以验证。证明该方案确实可行。The MLDP protocol is an extended protocol of the LDP protocol,which extends the LDP protocol to meet the needs of multicast.When implementing the MLDP protocol,the processing flow of the forwarding equivalence class FEC is crucial.The FEC must be created normally.The MLDP protocol can work normally,and the LSP may be established normally.This paper proposes a feasible FEC processing scheme when implementing the MLDP protocol.This program focuses on the FEC creation process and does not describe the FEC deletion and release process.The program can successfully create FEC and make it work properly.This paper describes the processing flow of FEC in detail through several possible situations and verifies it through simulation.Prove that the program is indeed feasible.
