DATA FLOW GUIDING APPARATUS AND DATA FLOW GUIDING METHOD IN VIRTUAL NETWORK

摘要

A data flow guiding apparatus and a data flow guiding method in a virtual network, relating to the technical field of virtual networks. In the data flow guiding apparatus, a first virtual machine, a second virtual machine, and a security service node are respectively connected to a virtual switch, and a flow table is used for indicating routing rules for the virtual switch to transmit data. When performing flow guiding by means of the data flow guiding apparatus, during the entire data flow guiding process, there is no need to package data by means of a virtual machine network gateway, and the virtual machines do not need to implement data flow guiding by means of a memory transfer method. Thus, for the security service node, there is also no need to pre-clarify the protocol used by a virtual network gateway to package the data and there is no need to pre-customise and develop an API interface matching memories of the virtual machines; correspondingly, there is no need to perform a large amount of adaptation for security service nodes provided by a third party, thereby increasing the application flexibility of the data flow guiding apparatus.
