Network management system and network management method

Abstract

The invention discloses a network management system and a network management method. A network management foreground can associate a virtual network interface card (vNIC) and configuration corresponding to a configuration identifier according to a binding relation between the vNIC and the configuration identifier; and moreover, through the interaction with an access switch, the network management foreground can identify a starting event and a stopping event of a virtual memory (VM) as well as an access position of the vNIC when the VM is started and stopped. Therefore, even if the vNIC is migrated along with the VM in a virtual network, the dynamic migration of the configuration of vNIC in a physical network can be realized through the variation of the access position of the vNIC when the VM is started and stopped, so that the configuration maintenance work can be alleviated. In addition, when the variation of the access position of the vNIC is identified by the network management foreground, the migration historic record of the vNIC also can be recorded, so that the migration tracking can be realized.

Description

technical field [0001] This application relates to EVB (Edge Virtual Bridging, edge virtual bridging) technology, in particular to the configuration of vNIC (Virtual Network Interface Card, virtual network adapter) used to manage VM (Virtual Machine, virtual machine) under the EVB architecture in the physical network A network management system and a network management method. Background technique [0002] Such as figure 1 As shown, under the EVB framework, VMs that provide various services can be hosted in physical servers. Wherein, each VM has a vNIC, and can use the vNIC to access the vPort (Virual Port, virtual port) configured on the access switch. Therefore, based on the interconnection between the physical server and the access switch in the physical network, the Realize the interconnection between VMs in different physical servers, and form a virtual network by interconnecting VMs in different physical servers. Moreover, according to actual needs, VMs in the virtu...

Problems solved by technology

Therefore, if a VM in any physical server is migrated to another physical server in the virtual network and the vPort connected to the vNIC of the VM changes, you need to manually delete the configuration of the original vPort before migration, and After the migration, the vPort is reconfigured. In this way, the configuration of the vNIC in the physical network cannot be dynamically migrated, resulting in cumbersome configuration and maintenance work.
