Problems solved by technology

[0007] The main purpose of the present invention is to provide a virtual router method, device and system to at least solve the problem of realizing virtual routers in the above-mentioned related technologies, mainly in middle and high-end router products. On the one hand, the cost is relatively high, and on the other hand, virtual The number of virtual devices produced is not large, so when a large number of virtual routers are required, especially in low-end application scenarios, a low-cost virtual router implementation solution is required

Embodiment 1

[0056] In this embodiment, a router is connected to a routing processing server through a network or an Ethernet switch to implement a virtual router as an example for illustration.

[0057] In this embodiment, without completely changing the existing router system architecture, through an extensible, external routing processing server, and through programming the control software and related functions of the existing router, that is, through the method of software upgrade, Support for virtual router implementations.

[0058] Figure 5 It is a structural schematic diagram of implementing a virtual router through routing processing server extension, and connecting the external routing service processor RP extension through the RP extension network to realize a virtual router.

[0059] Wherein, the hardware part of the routing processing server may be implemented by a PC cluster or a PC server cluster. The routing processing server can also be realized by a blade server, or it...

Embodiment example 2

[0081] In this embodiment, the route processing server implements a virtual router by extending a route processing module (also called a route processing unit) of the router.

[0082] Figure 6 It is a schematic diagram of the equipment structure of the implementation scheme of the virtual router for extending the routing processing unit.

[0083] Such as Figure 6 As shown, compared with the implementation case 1, this embodiment is a dedicated system, which adopts an independent device design form to realize the virtual router. In this embodiment, by introducing one or more routing expansion processing boards (typically, a routing processing expansion board) into the router, this can not only realize the expansion of functions, but also ensure that the structure of the device is relatively compact and has a low cost. advantage. Of course, the use of multiple expansion boards is not excluded). It includes: a processor, and related memory, and / or a hard disk unit, so as to ...

Abstract

The invention discloses a virtual router system and a method for realizing the virtual router. Wherein, the virtual router system includes: a router and a routing processing server; the router includes an interface module, wherein the interface module includes: a packet processing function module, a forwarding module, and one or more forwarding tables, wherein one or more of the interface modules A physical interface or a sub-interface of a physical interface is allocated to different virtual routers, and the physical interfaces or sub-interfaces are in one-to-one correspondence with the virtual routers; the routing processing server includes multiple routing processors, wherein the routing processors correspond to the virtual routers in a one-to-one manner. , each routing processor is used to execute the routing processing function of its corresponding virtual router. By adopting the invention, the virtual router can be realized flexibly at low cost.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method, device and system for realizing a virtual router. Background technique [0002] In order to improve resource utilization or reduce costs, the use of virtualization technology is becoming more and more popular, such as the realization and general use of virtual machine technology that virtualizes one computer into multiple computers, and the virtualization of routers. , the virtualization of other network devices, and even the virtualization of the network, etc., have also been accepted by the industry and deployed. The virtualization of routers has different names according to the implementation method or the understanding of different companies. For example, it is called a virtual router or a logical router. A classification method is that when a router is virtualized into multiple physically independent routers, it is called a logical router, and when it shares mor...
