一种转发专线业务报文的方法及装置
摘要：
本发明的实施例提供一种转发专线业务报文的方法及装置，涉及通信领域，无需增加或改动现有各IP承载网络的配置，实现专线业务报文在网络域进行传输。包括：第一接入网关获取专线业务报文；确定通用路由封装GRE隧道，GRE隧道的源IP地址为第一接入网关的IP地址，GRE隧道的目的IP地址为第二接入网关的IP地址；获取PW标签；执行MPLS封装，得到MPLS封装专线业务报文；对MPLS封装专线业务报文执行GRE封装，得到GRE封装专线业务报文；通过GRE隧道向第二接入网关发送GRE封装专线业务报文。用于传输专线业务报文。
摘要（英）：

The embodiment of the present invention provides a method and device for forwarding a special line service packet, relating to the field of communication. The adding or change of the configuration of an existing each IP bearer network is not needed, and the transmission of the special line service packet in a network domain is realized. The method comprises the following that: a first access gateway obtains the special line service packet; a general router is determined to package a GRE tunnel, the source IP address of the GRE tunnel is the IP address of the first access gateway, and the destination IP address of the GRE tunnel is the IP access of a second access gateway; a PW label is obtained; the MPLS packaging is executed, and an MPLS packaging service message is obtained; the GRE packaging of the MPLS packaging service message is executed, and the GRE packaging special line service is obtained; and the GRE packaging special line service is sent the second access gateway through the GRE tunnel. The method and the device are used for transmitting service packets.
