Network management system and method

Abstract

The invention discloses a network management system and is applied to a cloud network. The cloud network comprises a cloud management platform, a virtual switch and a physical switch. The network management system comprises a first controller which is used for receiving first configuration of the cloud management platform for the virtual switch, issuing the first configuration information to the virtual switch to enable the virtual switch to execute the first configuration information and generating description information of the first configuration information at the same time; and a second controller which is used for receiving second configuration information input by a user and processing the second configuration information according to the description information and is also used for sending the processed second configuration information to the virtual switch or / and the physical switch according to a preset strategy to enable the virtual switch or / and the physical switch to execute the processed second configuration information. The invention further provides a network method. According to the invention, cloud network configuration can be more flexible and balanced, and the system availability is improved.

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 a cloud network, and each physical server will run multiple virtual machines. 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 NICs are cascaded with physical switches to form a network topology in which physical switches and virtual switches are interconnected at multiple levels. [0003] For the management of each virtual machine in the cloud network, the current method is to control each virtual switch through the cloud management platform (such as openstack), so that the "virtual switch" can realize the network function for the virtual machine in the cloud platform. Such as VLAN, VxLAN, L3 routing, L2 sw...

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
