Embodiment Construction

[0036] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0037] figure 1 It is a flowchart of a virtual machine policy migration configuration method in an embodiment of the present invention; refer to figure 1 , the method includes:

[0038] S101: Obtain a rule set R matching the virtual machine to be migrated from the flow table A ;

[0039] It should be noted that the flow table is the most basic basis for a software-defined network (Software Defined Network, SDN) switch to process data packets, and it directly affects the efficiency of data forwarding and the performance of the entire network. The flow table is managed by a centralized controller, generated by sensing the topology view of the entire network, and sent to al...

Abstract

The invention discloses a strategy migration configuration method and a strategy migration configuration device of a virtual machine, relating to the technical field of networks. According to the invention, a rule set RA matched with a virtual machine to be migrated is obtained from a stream table; an optimal migration target address is inquired from idle IP (Internet Protocol) addresses based on the rule set RA; rules in the rule set RA are reconfigured according to a network configuration environment of the migration target address; strategy configuration can be realized without artificial participation; increasing of a strategy space due to the migration operation of the virtual machine is effectively reduced; the number of newly increased fragment strategies is reduced; the inquiry forwarding efficiency of a controller and network equipment is further increased; and furthermore, the strategy migration configuration method is easy to realize and low in algorithm complexity.

Description

technical field [0001] The invention relates to the field of network technology, in particular to a virtual machine policy migration configuration method and device. Background technique [0002] In the data center network, there are hundreds of virtual machines to provide network services for multi-tenants. In order to meet the flexibility in terms of resource optimization, fault tolerance, load balancing, etc., these virtual machines need to be migrated in a timely and effective manner on different hardware devices. For example, when a virtual machine cannot continue to provide services to tenants due to a system failure, the application information and user information on the virtual machine need to be migrated to another virtual machine, and in order to ensure that the service is not interrupted by the migration operation, It is also necessary to modify the configuration information of the network accordingly. Or when the network load of a physical device is too heavy,...
