Abstract

The invention discloses a software switch load balancing method comprising the following steps that (1) network port binding is set; (2) the network port rate in the network binding is acquired; (3) ordering parameters are calculated according to the network port rate and the data transmission volume within a certain period; (4) available network ports are ordered according to the ordering parameters; (5) the ordering result is processed and whether load migration is triggered is judged; (6) if load migration is triggered, the load required to be migrated is selected according to the type of the load; and (7) the load is migrated and the network port used by the migrated load is changed. The invention also discloses a software switch performing the method. With application of the method, the network port rate is included in the load balancing process, the network port rate information is acquired and the load type is judged; meanwhile, the method has a load selection mechanism before migration so that reasonable load balancing can be performed.

Description

Technical field [0001] The invention belongs to the technical field of computing system virtualization networks, and specifically relates to a load balancing method of a software switch and a software switch, and is suitable for a virtualized network environment where multiple virtual machines are interconnected. Background technique [0002] As a component of cloud computing technology, virtualization technology has been expanding its application scale. The network between virtual machines is larger and the structure is more complex. This leads to more and more complex virtual machine network configurations. It takes longer and more complicated to configure the network. operating. Virtual machines need more automated and flexible network access methods. Virtual machine networks need programmable control interfaces to realize automatic network configuration and support advanced functions such as access control, flow control, and load balancing. [0003] Virtual machine network acc...
