Embodiment Construction

[0023] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] The technical solution provided by the present invention is applied to a data center network selected for multi-ISP network access. The data center network includes a plurality of egress routers, and for each egress router, execute figure 2 The following steps are shown:

[0025] Step 201, after the egress router receives the first message from the ISP network side, if it is determined that there is no entry containing the source IP address of the first message in the established IP flow forwarding table, then in the IP flow forwarding table Add an entry that includes the following content: the source IP address of the first message, the interface that receives the first message, and the router that sends the first message to the interface...

Abstract

The invention provides a message transmission method and an egress router, wherein the method comprises the following steps: A) after the egress router receives a first message from an ISP (Internet service provider) network side, if the situation that a table item containing the source IP (Internet protocol) address of the first message does not exist in an established IP stream forwarding table is determined, the table items containing the following contents are increased in the IP stream forwarding table: the source IP address of the first message, an interface receiving the first message and a router arranged in the ISP network side and used for sending the first message to the interface, and the first message is forwarded according to a target IP address of the message; and B) after the egress router receives a second message from a data center network side, the table item containing the target IP address of the second message is looked up in the IP stream forwarding table, the interface in the table item which is looked up is taken as an outgoing interface for sending the second message, the router in the table item which is looked up is taken as the next hop, and the second message is forwarded to the next hop through the outgoing interface.

Description

technical field [0001] The invention relates to network communication technology, in particular to a message transmission method and an egress router. Background technique [0002] Data center reliability is increasingly becoming one of the key indicators for operators. Compared with relying on a single Internet Service Provider (ISP: Internet Service Provider) network to provide line lease in the past, today's data center network is more inclined to choose multiple ISP network access to ensure joint provision of line lease services. This can ensure that when the line provided by a certain ISP network fails, the line provided by the backup ISP network can be used to ensure that the access to the data center from the external network will not be interrupted for a long time. [0003] Take the data center network to choose dual ISP networks, that is, ISP A network and ISP B network access to provide lines as an example, as follows: figure 1 shown. exist figure 1 , if user t...
