Problems solved by technology

In addition, in a virtualized environment, due to system management, virtual machine migration and other reasons, the IP address of the virtual machine may change at any time
[0004] However, the isolation configuration of traditional firewalls is based on IP addresses.

Abstract

The embodiment of the invention discloses a method and a system for realizing data transmission between virtual machines. The method comprises that: a first proxy server receives the information of a data packet which is transmitted to a target virtual machine by a source virtual machine, forwards the data packet to a second proxy server serving the target virtual machine if no local information forbids the transmission of the data packet from the source virtual machine to the target virtual machine, otherwise does not transmit the data packet; and the second proxy server receives the data packet, judges whether the data packet receiving right information of the target virtual machine permits the forwarding of the data packet to the target virtual machine or not, forwards the data packet to the target virtual machine if the data packet receiving right information of the target virtual machine permits the forwarding of the data packet to the target virtual machine, and does not transmit the data packet if the data packet receiving right information of the target virtual machine does not permit the forwarding of the data packet to the target virtual machine. The embodiment of the invention can avoid the influence of the change of an IP address of the virtual machine on the data transmission between the virtual machines.

Description

technical field [0001] The present invention relates to the field of network data transmission, more specifically, to a method and system for realizing data transmission between virtual machines. Background technique [0002] With the emergence and development of virtualization technology, a user can simulate one or more virtual machines (Virtual Machine, "VM" for short) on a physical server. Typically, a physical machine can host two or more virtual machines. After the virtual machine is successfully created, the user can start the virtual machine arbitrarily, stop the started virtual machine, and then restart the previously stopped virtual machine. [0003] In practical applications, when a user restarts a stopped virtual machine, the network may assign an IP (Internet Protocol, a protocol for interconnecting networks) address to the restarted virtual machine. For the virtual machine, the IP address currently assigned to it may be different from the IP address assigned t...
