Virtual network switch system and method of constructing the same

A virtual network switch system comprising:

• at least one storage unit configured to store a plurality of modules, being a collection of instructions of an application operable in the system;
• at least one processor configured to execute the plurality of modules, the modules comprising:
• a building module configured to receive a command and build a virtual switch, a plurality of virtual servers, and a plurality of virtual NICs in a server according to the command;
• a mapping module configured to build a mapping relation between a first virtual server of the virtual servers and at least one first virtual NIC of the virtual NICs according to network requirement of the first virtual server, and transmit an access request of the first virtual NIC to a first physical NIC through the virtual switch;
• and
• a determining module configured to determine whether an available resource of the first physical NIC is less than a predetermined value;
• a control module configured to control the first physical NIC to allow access by the first virtual NIC in response to the available resource of the first physical NIC being greater than the predetermined value.
• wherein a plurality of physical NICs is connected to the server and the first physical NIC of the physical NICs is matched with the first virtual NIC.

A server connected to a plurality of physical NICs, the server comprising:

• at least one storage unit configured to store a plurality of modules, being a collection of instructions of an application operable in the system;
• at least one processor configured to execute the plurality of modules, the modules comprising:
• a building module configured to receive a command and build a virtual switch, a plurality of virtual servers, and a plurality of virtual NICs in the server according to the command;
• a mapping module configured to build a mapping relation between a first virtual server of the virtual servers and at least one first virtual NIC of the virtual NICs according to network requirement of the first virtual server, and transmit an access request of the first virtual NIC to a first physical NIC of the physical NICs through the virtual switch;
• and
• a determining module configured to determine whether an available resource of the first physical NIC is less than a predetermined value;
• a control module configured to control the first physical NIC to allow access by the first virtual NIC in response to the available resource of the first physical NIC being greater than the predetermined value.
• wherein the first physical NIC is matched with the first virtual NIC.
