Problems solved by technology

When the IPoE client uses this IPv6 address to send a service message to the BRAS, after the BRAS receives the service message, it cannot forward the service message of the IPoE client because there is no IPv6 address corresponding to the IPoE client in the forwarding table , causing the IPoE client to fail to access the network normally

Embodiment Construction

[0026] Aiming at the problems existing in the prior art, the embodiment of the present invention provides a method for processing service packets, so as to figure 1 It is a schematic diagram of an application scenario of an embodiment of the present invention, and the method is applied in a network (such as an IPoE network) including a BRAS, an IPoE client, and an authentication server. Wherein, the IPoE client is a client (such as a terminal device) that accesses the Internet in an IPoE manner. As the access device of the IPoE client, the BRAS can send service packets from the IPoE client to the Internet or discard service packets from the IPoE client. The authentication server is used to authenticate the IPoE client. In the above application scenarios, such as figure 2 As shown, the processing method of the service message may specifically include the following steps:

[0027] In step 201, the BRAS receives a router request message from an IPoE client, obtains a routing ...

Abstract

The invention discloses a service message processing method and a service message processing device. The method includes the following steps: after receiving a router request message coming from an IPoE (IP over Ethernet) client, a BRAS (broadband remote access server) obtains a routing prefix corresponding to the IPoE client, and sends a router notification message carrying the routing prefix to the IPoE client; the BRAS generates a temporary forwarding table entry corresponding to the IPoE client, and the temporary forwarding table entry includes forwarding information and the routing prefix which correspond to the IPoE client; after receiving a service message coming from the IPoE client, the BRAS obtains forwarding information and a source IPv6 address which correspond to the service message; if the source IPv6 address corresponding to the service message is matched with the routing prefix in the temporary forwarding table entry and the forwarding information corresponding to the service message is matched with the forwarding information in the temporary forwarding table entry, then the BRAS allows the forwarding of the service message. In the embodiment of the invention, IPoE clients can normally access a network.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method and equipment for processing service messages. Background technique [0002] Such as figure 1 As shown, it is a schematic diagram of the IPoE (IP over Ethernet, IP forwarding based on Ethernet) network. After the IP packet of the IPoE client is encapsulated by Ethernet, it is sent to the BRAS (Broadband Remote Access Server, broadband remote access server )superior. In an IPoE network, an IPoE client can obtain an IPv6 address through an IPv6 stateful access method, or obtain an IPv6 address through an IPv6 stateless access method. When obtaining an IPv6 address through IPv6 stateless access, the IPoE client sends a router solicitation message to the BRAS, and the BRAS sends a router advertisement message to the IPoE client after receiving the router solicitation message. Carry the route prefix allocated for IPoE clients. [0003] Based on the routing p...
