Embodiment 1

[0046] figure 2 It is a flow chart of Embodiment 1 of the cluster network path control method of the present invention. This method is applicable to the control of the traffic path of the cluster network, especially the control of the traffic path of the virtual cluster network based on the BGP protocol. The method can be controlled by the cluster network controller implementation. Such as figure 2 As shown, the method can be carried out as follows:

[0047] S201. The controller in the first network determines a forwarding path, where the forwarding path is the path through which a message is sent from an edge device in the second network to an edge device in the third network via the routing device in the first network path.

[0048] In the cluster network, different from the traditional network deployment, the controller (Controller) replaces the Route Reflector (RR) in the traditional network to perform path calculation and planning for the intra-cluster network, and c...

Embodiment 2

[0068] Figure 4 It is a flow chart of Embodiment 2 of the cluster network path control method of the present invention. This method is also applicable to the control of the traffic path of the virtual cluster network based on the BGP protocol. The method can be implemented by the first routing device of the cluster network. Such as Figure 4 As shown, the method can be carried out as follows:

[0069] S401. The first routing device in the first network receives the first routing information sent by the controller in the first network after determining the forwarding path, the first routing information includes identification information, and the identification information indicates the forwarding path, The forwarding path is the path through which the packet is sent from the edge device in the second network to the edge device in the third network via the routing device in the first network. A routing device that has a neighbor relationship with the edge device in the second ...

Embodiment 3

[0083] Figure 5 It is a structural schematic diagram of an embodiment of the controller of the present invention, such as Figure 5 As shown, the device may include: a processing module 51 and a first sending module 52 . Wherein, the first processing module 51 can be used to determine a forwarding path, the forwarding path is that the message is sent from the edge device in the second network to the edge device in the third network via the routing device in the first network Path passed: the first sending module 52 may be configured to include identification information in the first routing information sent to the first routing device, where the identification information indicates the forwarding path, so that the first routing device determines whether to Send the second routing information to the edge device in the second network, where the first routing device is a routing device in the first network that has a neighbor relationship with the edge device in the second netw...

Abstract

Embodiments of the present invention provide a cluster network path control method, equipment, and cluster network system. The cluster network path control method of the present invention includes: the controller in the first network determines the forwarding path, and the forwarding path is that the message is sent from the edge device in the second network and sent to the third network via the routing device in the first network The path passed by the edge device; the first routing information sent by the controller in the first network to the first routing device contains identification information, and the identification information indicates the forwarding path, so that the first routing device determines whether to send the first routing information to the first routing device according to the identification information. The edge device in the second network sends the second routing information, and the first routing device is a routing device in the first network that has a neighbor relationship with the edge device in the second network. The embodiment of the present invention realizes the path control of the controller for the external flow entering the cluster network, and solves the problem that the path cannot be controlled when the external flow enters the cluster network.

Description

technical field [0001] The embodiments of the present invention relate to network technology, and in particular to a cluster network path control method, equipment and cluster network system. Background technique [0002] With the rapid development of network technology, the cluster network has replaced the traditional network as the most important data network due to its advantages of high management and control efficiency and high flexibility. [0003] However, with the increase of data services, how to control the optimization of traffic paths becomes extremely important. figure 1 It is a network architecture diagram of a cluster network in the prior art, such as figure 1 As shown, the controller 101 can determine the autonomous system (Autonomous System, referred to as AS) traffic path through calculation, for example, the controller 101 can calculate and determine that the traffic path 102 from AS2 to AS1 is a customer edge device (Customer Edge, referred to as CE) 2- ...
