Problems solved by technology

[0007] The technical problem to be solved by the present invention is to provide a routable virtual switching method, overcome the technical deficiency that the existing V-SWITCH technology cannot simultaneously support virtual switching and three-layer routing on a device interface at the edge of network access, and solve V-SWITCH technology. Switch technology cannot simultaneously provide Layer 2 data exchange functions and rich Layer 3 services for access customers on the same interface; and, through the present invention, operators can simultaneously provide high-efficiency Layer 2 services for large customers on one interface. The virtual switching function can also provide powerful business processing capabilities, such as the expansion capabilities of MPLS, multicast, VPN, and IPV6, without adding more equipment and access lines

Embodiment Construction

[0054] In the present invention, the technical scheme of the routable virtual switching method is:

[0055] A: Determine the priority of switching and routing processing on an interface;

[0056] B: Waiting for the arrival of the device interface data message;

[0057] C: Check the legality of the data message, and discard the wrong data message if the message does not meet the legality;

[0058] D: According to the determined processing priority, exchange processing is performed according to the incoming VLAN ID and incoming interface number of the message, or identify and process according to the layer-3 routing or protocol information carried in the message. After the packet fails to be processed by the priority process, it will not be discarded, but will be processed by the low priority process.

[0059] Further, step D may include the following information:

[0060] D1: Switching processing is a process of searching the switching table according to the incoming VLAN ID...

Abstract

A virtual switching method which could be routed, includes: STEP 1,determining the processing priority level of switching and routing at a interface; STEP 2 , waiting for the arrival of the data message of the equipment's interface ; STEP 3,performing the switching process according to the processing priority level which determined at the interface ,the input virtual LAN identification and the input interface number of the message , or performing the identifying and processing according to the three ply route or protocol information in the message .Of which if the processing procedure of the message is failed , the message will not be discarded , but processed with the low priority.

Description

technical field [0001] The invention relates to the technical field of data network communication, in particular to a routable virtual switching method. Background technique [0002] With the continuous increase of MAN users, the network scale and traffic also increase accordingly. The development direction of MAN networking has changed from star and tree to flat, diversified and customized development, and the network tends to be more flexible. Operators pay more attention to performance-price ratio, and at the same time pay more and more attention to the support of value-added services. The requirements for network equipment are no longer simple traffic access and aggregation. The business of the metropolitan area network is becoming more and more abundant, requiring high-end network equipment to have stronger business processing capabilities, especially higher requirements for the service processing capabilities of the network equipment at the aggregation layer: rich Laye...
