Title
(EN) Method, system and network element for packet forwarding path management
(ZH) 报文转发路径管理方法、系统及网元
Abstract
(EN)
The invention relates to a method, a network element and a system for packet forwarding path management. The method includes the steps: transmitting an address inquiring request carrying node information of a CN (correspondent node) to a mapping server by a first MAG (mobile access gateway); receiving the address inquiring request, inquiring a binding cache table and acquiring CN mobile access gateway information corresponding to the node information of the CN by the mapping server; directly transmitting an address inquiring answer message to the first MAG by the mapping server, or transmitting the address inquiring answer message to the first MAG by a second MAG after forwarding the address inquiring request to the second MAG; and receiving the address inquiring answer message by the first MAG. The CN mobile access gateway information points to the second MAG, and the address inquiring answer message carries the CN mobile access gateway information. The method, the network element and the system for packet forwarding path management solve the problem of flow forwarding bottleneck caused by LAM by the aid of a packet forwarding channel between the two MAGs.

本发明涉及一种报文转发路径管理方法、网元和系统,该方法包括:第一移动接入网关(MAG)向映射服务器发送地址查询请求,其中携带对端节点(CN)的节点信息;映射服务器接收地址查询请求,查询绑定缓存表,获取CN的节点信息对应的CN的移动接入网关信息,CN的移动接入网关信息指向第二MAG;映射服务器直接向所述第一MAG发送地址查询应答消息,或向第二MAG转发地址查询请求后,第二MAG向第一MAG发送地址查询应答消息,其中携带CN的移动接入网关信息;第一MAG接收地址查询应答消息。本发明报文转发路径管理方法、网元和系统通过两个MAG之间的报文转发通道解决了因LAM造成的流量转发瓶颈的问题。
