Virtual network switch system and establishment method thereof

Abstract

The invention discloses a virtual network switch system, comprising a server and a plurality of network interface cards. The server comprises an establishment module, a mapping module and a judgment module. The establishment module is used for establishing a virtual switch, a plurality of virtual servers and a plurality of virtual network cards. The mapping module is used for forwarding mapping requests of the virtual network cards in mapping connection with the mapping module to the network interface cards matching the virtual network cards through utilization of the virtual switch accordingto network demand information of the virtual servers. The judgment module is used for judging whether available resources of the network interface cards are smaller than an alarm value or not. The mapping module is also used for controlling the network interface cards to selectively receive the mapping requests of the virtual network cards according to a judgment result. The invention also provides an establishment method for the virtual network switch system. According to the virtual network switch system and the establishment method thereof, the necessary cost of upgrading a network device due to expansion of network business demands can be reduced, and the network interface cards of various interface standards are supported.

Description

technical field [0001] The invention relates to the field of communication networks, in particular to a virtual network switch system and its establishment method. Background technique [0002] IEEE802.3 interface standards include 10GbE, 40GbE, 100GbE, etc., so that in the network application environment, switches need to have a variety of network interfaces with different connection specifications, and most switches currently only support one or two network interfaces with connection specifications If you need more than three standard network interfaces, you need to purchase a core switch, which is expensive, which will make it more expensive for enterprises to upgrade network equipment due to the expansion of business needs. Contents of the invention [0003] In view of the above, it is necessary to provide a virtual network switch system, which can support more than three network interfaces with connection specifications, and has low cost. [0004] An embodiment of th...
