RFC3063 MPLS（多协议标签交换）环路预防机制

本文讲述了一种基于“线程”的、用于防止多协议标签交换协议（MPLS）设置含有环路的标签交换路径(LSP)的简单机制。此机制与虚电路（VC）的合并相兼容，但此兼容u并不是必需的。该机制还可用于下游按需等级分配也可用于下游等级分配。在协议消息中对要传输的信息进行了紧密的捆绑（也就是，不需使用路径矢量）。当一个节点需要转换到它的下一跳时，分布式程序被执行。不过，这只针对那些下游变化的节点。-RFC3063 MPLS (Multi-protocol Label Switching) loop prevention mechanism described in this article which is based on " threads" , and is used to prevent multi-protocol label switching protocol (MPLS) to set the loop that contains the label switching path (LSP) of the simple mechanism. This mechanism and the virtual circuit (VC) is compatible with the merger, but this is compatible with u is not necessary. The mechanism can also be used downstream on-demand distribution of grades can also be used downstream distribution of grades. The message in the agreement to transfer the information to the close of the bundle (that is, without the use of the path vector). When a node needs to be converted to its next hop when the distributed program is executed. However, this change for those downstream nodes.
