Problems solved by technology

[0005] It can be seen that in the prior art, the method of sending and receiving data based on a virtual machine needs to split larger data packets. Transmitting a large number of data packets will cause a large system overhead for Host and Guest
In addition, since the Guest needs to send ACK packets one by one for each data packet, the overhead to the Guest is further increased

Abstract

The invention discloses a data transmission method, a data receiving method and a system based on a virtual machine. The data transmission method is applied to a virtual machine framework provided with a host and a client. The method includes the steps that a back end virtual network device of the host acquires data of a socket buffer area; data slots of the data of the socket buffer area are stored in the form of a chain table, wherein the size of the data slots is equal to that of a data package sent by a physical network card of the host; and the data slots are mapped to a shared memory area so that the client can read the data slots from the shared memory area conveniently. According to method or the system, separation of big data packages can be avoided, and system overhead of the Host can be reduced.

Description

technical field [0001] The present invention relates to the field of data transmission, in particular to a virtual machine-based data sending method, receiving method and system. Background technique [0002] A virtual machine (Virtual Machine) refers to a complete computer system that is simulated by software, has complete hardware system functions, and runs in a completely isolated environment. Through virtual machine software, one or more virtual computers can be simulated on a physical computer. A virtual machine can work like a real computer, such as installing an operating system, installing applications, accessing network resources, and so on. [0003] Usually, the physical computer where the virtual machine is located is called a host (Host), and the virtual machine itself is called a client (Guest). [0004] In the Xen virtual machine architecture, the process of sending data from the host to the client is mainly: the Netback of the host (the back-end virtual netw...
