Network management system and method

Abstract

A network management system, which is applied to a cloud network, and the cloud network includes a cloud management platform, a virtual switch, and a physical switch, including: a first controller for receiving first configuration information of the virtual switch from the cloud management platform, and converting the first configuration information sending to the virtual switch to make the virtual switch execute the first configuration information, and generate the description information of the first configuration information at the same time; the second controller is used to receive the second configuration information input by the user, and perform the second configuration information according to the description information Processing; the second controller is further configured to send the processed second configuration information to the virtual switch or / and the physical switch according to a preset policy, so that the virtual switch or / and the physical switch executes the processed second configuration information. The invention also provides a network method. The invention can make cloud network configuration more flexible and balanced, and improve system availability.

Description

technical field [0001] The present invention relates to the field of network communication, in particular, to a network management method and system. Background technique [0002] At present, there are usually many physical servers in the cloud network, and multiple virtual machines will run on each physical server. The virtual machines on the physical server are usually connected by a virtual switch, and the virtual switch uses one or more physical network cards of the physical server as The uplink NIC is cascaded with the physical switch to form a network topology in which the physical switch and the virtual switch are interconnected in multiple stages. [0003] For the management of each virtual machine in the cloud network, a current method is to control each virtual switch through a cloud management platform (such as openstack), so that the "virtual switch" can realize the network function for the virtual machine in the cloud platform, For example, functions such as VL...

Problems solved by technology

However, this approach may prevent the coordination and division of labor between the physical switch and the "virtual switch". At the same time, because the traffic of some virtual machines is directly exchanged and processed through the virtual switch and does not reach the "physical switch", this makes the The physical switch is invisible to these traffic, that is, it cannot do any processing, which is equivalent to the failure of related functions
