Abstract

The invention discloses a network control system and a network switching adapter. The network control system comprises a physical server and a physical switch. The physical server further comprises at least one virtual machine and a the network switching adapter, wherein the virtual machines are used for transmitting data packets; the network switching adapter is used for receiving the data packets from the virtual machines, adding tags to the data packets, and forwarding the data packet with the tags to the physical switch, and the tags are used for indicating the virtual machines to which the data packets belong; and the physical switch is used for receiving the data packets from the network switching adapter, and finishing network control according to the data packets. According to the network control system, the network switching adapter is used for transmitting the data packets to the physical switch to realize a network control function, so that the occupied resources of the physical server are greatly reduced, the function of the physical switch is fully utilized, and network control efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of virtualized network control, in particular to a network control system and a network exchange adapter. Background technique [0002] In a traditional virtualized network control solution, a virtual switch is applied in a physical server to complete the network control function of a virtual machine. [0003] figure 1 It is a schematic diagram of the data packet transfer process in the prior art network control system. Such as figure 1 As shown, first the data packet will be sent to the virtual switch, and the virtual switch will control the network policy of the data packet. Specifically, the virtual switch first parses the data packet to obtain the source address and destination address of the data packet, and then sends the data packet to the virtual switch If the data packet conforms to the control strategy, the data packet will be sent with the source address and destination address; if the data pac...
