Embodiment Construction
[0021] In order to make the object, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below with reference to the accompanying drawings and examples.
[0022] In the present invention, in order to realize traffic intercommunication between virtual devices in the distributed switching and routing system, the forwarding chip is used as the smallest unit for joining and exiting VD in the distributed switching and routing system, and the correspondence between the forwarding chip and VD is established. relation.
[0023] see figure 2 , figure 2 It is a flowchart of a method for realizing traffic intercommunication between virtual devices according to an embodiment of the present invention, and mainly includes the following steps:
[0024] Step 201, setting a virtual port for the current VD to be interconnected with other VDs, configuring the virtual port as a Layer 3 interface of the ...

Abstract
The invention discloses a method and equipment for realizing traffic intercommunication between virtual devices. The technical solution is: setting a virtual port for each VD for interconnection with other VDs and configuring the virtual port as a three-layer interface, using the three-layer layer interface for route learning and virtual port port information notification; when any VD receives a message that needs to be sent to the user equipment subordinate to other VD, it determines the IP address of the virtual port of the other VD by looking up the routing table and ARP learning and the MAC address, and then determine the port number of the virtual port of the other VD according to the port information of the virtual port advertised by other VDs, so that the message is sent to the virtual port, so that the other VD can forward the message to the destination user equipment. The invention can reduce the networking cost of users.
Description
technical field [0001] The present application relates to the technical field of communications, and in particular to a method and device for realizing traffic intercommunication between virtual devices. Background technique [0002] see figure 1 , figure 1 It is a logical block diagram of a distributed switching routing system in the prior art, including four forwarding chips: PP1, PP2, PP3, PP4, and a switching network, each of which has a corresponding switching network port fp and multiple subordinate user ports up, where the switching network ports corresponding to PP1, PP2, PP3, and PP4 are fp1, fp2, fp3, and fp4 respectively, and each forwarding chip has four user ports, represented by up1, up2, up3, and up4. [0003] In the prior art, the forwarding chip is responsible for the forwarding processing of the message, analyzes the destination forwarding chip and the destination port of the message according to the forwarding process, and is responsible for sending the ...
