Abstract

The invention provides a method and a system for realizing flow intervals among virtual devices. The method is applied to a distributed switching and routing system, and comprises the following steps of: setting forwarding chips into minimum units logging in and out of the virtual devices (VD), and establishing correspondence between the forwarding chips and the VDs; establishing independent logical channels for the VDs in a switched network; and performing flow forwarding through the logical channels by using the forwarding chips. By the scheme provided by the invention, the forwarding chips do not establish the logical channels for the VDs per se, and are not required to have a virtualization function, so the cost of the forwarding chip is reduced, and the cost of the whole system is also reduced. In addition, the switched network can establish the logical channels for each VD, all the forwarding chips perform the flow forwarding by the logical channels established by the switched network, and similarly, the flow interval between the VDs is realized.

Description

technical field [0001] The invention relates to switching routing technology, in particular to a method and system for realizing flow isolation between virtual devices. Background technique [0002] In a distributed switching and routing system, one large physical device can be virtualized into multiple small devices, that is, a virtual device (VD, Virtual Device). Each VD is like an independent small device for users, which can independently run routing processes, layer-2 protocols, and layer-3 protocols, and can have independent forwarding entries and interfaces, and can also add its own users, independently start and read Get your own configuration files and more. The resources among various VDs can be allocated and managed through commands, and they will not be affected by each other. Even if the resources occupied by a certain VD exceed the allocated resource limit, other VD resources cannot be preempted. [0003] Virtualizing a large physical device into multiple sma...
