Embodiment 1

[0024] see figure 1 , this embodiment provides a method for forwarding a message, including:

[0025] 101: The router receives the first packet through a first interface of the router, where the first interface is a user edge side interface or a wide area network side interface;

[0026] 102: The router queries a virtual routing forwarding entry corresponding to the destination address of the first packet according to the destination address of the first packet received from the first interface, where the The VRF entry corresponding to the destination address of the text includes a first next hop and a second next hop, the first next hop is the address information or invalid address information of the application acceleration device, and the second next hop is the The next hop on the routing path corresponding to the destination address of the first message, the first next hop is used to guide the forwarding of the message received from the first interface, and the second nex...

Embodiment 2

[0038] This embodiment provides a method for forwarding packets. In this embodiment, the network service provider includes two types of devices: provider edge (full English name is Provider Edge, English abbreviation is PE) device and application acceleration device. Among them, the PE device is a router. The PE device is responsible for forwarding the application packets. For the uplink packets, they are forwarded to the application acceleration device. After the accelerated processing by the application acceleration device, the packets are sent back to the PE device, and then forwarded to the WAN or back to the user site. ; For the downlink message, it is first forwarded to the application acceleration device, and the message after accelerated processing by the application acceleration device is sent back to the PE device, and then forwarded to the user site or back to the remote user site.

[0039] In this embodiment, the application acceleration device receives the applica...

Embodiment 3

[0072] see Figure 4 , this embodiment provides a router, including: a first interface 301 , a second interface 302 , a query module 303 and a forwarding module 304 .

[0073] The first interface 301 is configured to receive the first message, where the first interface is a user edge side interface or a wide area network side interface;

[0074] The query module 303 is configured to query a virtual routing and forwarding VRF entry corresponding to the destination address of the first packet according to the destination address of the first packet received from the first interface, wherein the The VRF entry corresponding to the destination address of the message includes a first next hop and a second next hop, the first next hop is address information or invalid address information of the application acceleration device, and the second next hop is A next hop on the routing path corresponding to the destination address of the first message, the first next hop is used to guide t...

Abstract

The invention discloses a method, a router and a system of forwarding messages, and belongs to the technical field of communication. The method comprises that: the router receives a first message through a first interface of the router, wherein the first interface is a user border side interface or a wide area network side interface; and the router inquires a virtual routing forwarding (VRF) table entry corresponding to the destination address of the first message according to the destination address of the first message received through the first interface, wherein the VRF table entry corresponding to the destination address of the first message comprises a first next hop and a second next hop, when the first next hop is address information of an application accelerating device, the router confirms that the address information of the application accelerating device is a next hop of the first message, the first message is sent to the application accelerating device, application acceleration processing of the first message is conducted, and therefore a second message is obtained.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method, router and system for forwarding messages. Background technique [0002] With the rise of cloud computing, enterprises are migrating the IT equipment of the enterprise network to the data center, especially moving the server equipment of the branch office to the data center of the company headquarters or the data center of the operator. Doing so can greatly reduce the IT equipment purchase cost and operation and maintenance cost of the enterprise. But at the same time, it also brings performance problems, because most server applications are developed based on the LAN. After migrating to the WAN, too much interactive information will bring about a sharp drop in application performance. Among them, latency, response time, and protocol overhead are the main reasons why applications run slowly. Therefore, enterprises urgently need wide-area application acceleration...
