Embodiment 1

[0082] An embodiment of the present invention provides a gateway control method based on virtual machine migration, the first physical gateway is the physical gateway of the first physical server, and the second physical gateway is the physical gateway of the second physical server, such as figure 1 As shown, when the virtual machine is migrated from the first physical server to the second physical server, the method includes:

[0083] S101. The SDN controller acquires the IP address of the first virtual machine gateway, the MAC address of the first virtual machine gateway, and the VTEP IP address of the second physical server.

[0084] Wherein, the first virtual machine gateway is a virtual machine gateway of a virtual machine configured on the first physical gateway. The first physical server is the physical server where the virtual machine is located before migration, and the second physical server is the physical server where the virtual machine is located after migration....

Embodiment 2

[0100] An embodiment of the present invention provides a gateway control method based on virtual machine migration, the first physical gateway is the physical gateway of the first physical server, and the second physical gateway is the physical gateway of the second physical server, such as figure 2 As shown, when the virtual machine is migrated from the first physical server to the second physical server, the method includes:

[0101] S201. The SDN controller acquires virtual machine migration information, and the virtual machine migration information includes: the IP address of the virtual machine, the MAC address of the virtual machine, and the VTEP IP address of the second physical server.

[0102] Wherein, migrating the virtual machine from the first physical server to the second physical server includes: manually migrating the virtual machine to the second physical server; automatically migrating the virtual machine to the second physical server. The automatic migration...

Embodiment 3

[0146] An embodiment of the present invention provides an SDN controller, the first physical gateway is the physical gateway of the first physical server, and the second physical gateway is the physical gateway of the second physical server, which is applied to the migration of a virtual machine from the first physical server to the second Physical server process, such as Figure 5 As shown, the SDN controller may include: an acquisition unit 31 , a configuration unit 32 , a creation unit 33 and a sending unit 34 .

[0147] The obtaining unit 31 obtains the Internet Protocol IP address of the first virtual machine gateway, the media access control MAC address of the first virtual machine gateway, and the virtual tunnel terminal node VTEP IP address of the second physical server, and the first virtual machine gateway is configured in A virtual machine gateway for a virtual machine on the first physical gateway.

[0148] The configuration unit 32 is configured to control the se...

Abstract

The embodiment of the invention discloses a gateway control method, device and system based on virtual machine migration, and relates to the communication field. The gateway control method, device and system are used for solving the problem that when data transmission is carried out after virtual machine migration, the bandwidth for conducting data transmission between devices is occupied so that bandwidth resources can be wasted. According to the scheme, the gateway control method includes the steps that an SDN controller obtains the IP address of a first virtual machine gateway, the MAC address of the first virtual machine gateway and the VTEP IP address of a second physical server; the SDN controller controls a second physical gateway to configure a second virtual machine gateway on the second physical gateway for a virtual machine according to the VTEP IP address of the second physical server, the IP address of the second virtual machine gateway is the same as the IP address of the first virtual machine gateway, and the MAC address of the second virtual machine gateway is the same as the MAC address of the first virtual machine gateway; a first flow list item is created to enable the second physical gateway to forward data to the virtual machine according to a data forwarding strategy indicated by the first flow list item.

Description

technical field [0001] The present invention relates to the communication field, in particular to a virtual machine migration-based gateway control method, device and system. Background technique [0002] A virtual machine (Virtual Machine, VM) refers to a computer system that is simulated by software and has complete hardware system functions and runs on a physical server. A physical server can run multiple virtual machines at the same time, and each virtual machine uses a part of the physical resources of the physical server, such as CPU and memory. [0003] A virtual machine can be migrated from one physical server to another, and run on the migrated physical server to achieve server load balancing, online maintenance, and fault handling. Wherein, the physical gateway of the physical server where the virtual machine resides before migration is different from the physical gateway of the physical server where the virtual machine resides after migration, and at least one vi...
