Embodiment Construction

[0040] The application will be described in further detail below in conjunction with the accompanying drawings.

[0041] In a typical configuration of the present application, the terminal, the device serving the network and the trusted party all include one or more processors (CPUs), input / output interfaces, network interfaces and memory.

[0042] Memory may include non-permanent storage in computer-readable media, in the form of random access memory (RAM) and / or nonvolatile memory, such as read-only memory (ROM) or flash memory (flashRAM). Memory is an example of computer readable media.

[0043] Computer-readable media, including both permanent and non-permanent, removable and non-removable media, can be implemented by any method or technology for storage of information. Information may be computer readable instructions, data structures, modules of a program, or other data. Examples of computer storage media include, but are not limited to, phase change memory (PRAM), sta...

Abstract

The purpose of this application is to provide a method and device for communication based on an SDN network. This application captures the routing information of the first message through the main agent, wherein the main agent and the route passed by the first message are located at the same On the host: the master agent feeds back optimized packet information to the virtual machine associated with the first packet based on the routing information of the first packet, wherein the optimized packet information includes information about the virtual machine information, the virtual machine includes a sending virtual machine and a receiving virtual machine; an agent located on the same host as the virtual machine captures the optimized message information; exchanges the sending virtual machine and the receiving virtual machine according to the optimized message information Relevant information of the receiving virtual machine is used for communication between the sending virtual machine and the receiving virtual machine. Therefore, it has low delay, does not depend on the database, and guarantees that user services are not affected under any circumstances, and improves the reliability of the network.

Description

technical field [0001] The present application relates to the computer field, and in particular to a communication method and device based on an SDN network. Background technique [0002] With the rapid development of Internet technology and the increasing demand of users for the Internet, larger data centers with various capabilities have been established to meet the demand. Wherein, the development of virtualization technology enables a large number of virtual machines (Virtual Machine, VM) to be implemented in a data center, and these virtual machines can operate as physical machines in essence and perform various functions such as a web server or a database server. When two virtual machines (VMs) on different networks belong to different network segments, they cannot communicate directly. The traditional method is to use a router to find out the Media Access Control (MAC) address of the other party, and forward it through the router, but the router often becomes a bottl...
