Embodiment Construction

[0027] In order to make the object, technical solution, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0028] This paper proposes a method of NAT service strategy combined with Web redirection, which can dynamically adjust the destination address of client access according to the location of Web virtual server, and realize the optimization of client access path.

[0029] A message forwarding method for virtual server migration in the present invention, such as figure 2 As shown, the method includes the following steps:

[0030] Step 21, pre-configure the NAT service policy on the NAT service device of the first data center, the NAT service policy includes the redirection destination IP address, and the public network IP address and private IP address of the virtual server in the first data center. network IP address; the NAT service device is connecte...

Abstract

The invention discloses a method for forwarding a message about virtual server migration. The method includes: pre-configuring an NAT (network address translation) service strategy containing a redirected destination IP (internet protocol) address on NAT service equipment of a first data center; periodically detecting a private network IP address of a virtual server in the data center by the NAT service equipment of the first data center, when no response of the virtual server is received, confirming the virtual center is migrated from the first data center to a second data center; receiving a WEB request message of a client and with a public network IP address of the virtual server in the first data center by the NAT service equipment of the first data center, and returning a redirect message carrying the redirected destination IP address to the client according to the redirected destination IP address to request the client to send the WEB request message again to the destination IP address. The invention further discloses the NAT service equipment and a data center system, and message forwarding routes can be guaranteed not to circumambulate after the virtual server is migrated.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a message forwarding method, system and network address translation (NAT) service equipment for virtual server migration. Background technique [0002] A virtual machine (VM, Virtual Machine) refers to a complete computer system that is simulated by software and has complete hardware system functions and runs in a completely isolated environment. Through virtual machine software, users can simulate one or more virtual computers on a physical computer. These virtual computers work exactly like real computers. For example, users can install operating systems, install applications and Access to network resources and more. To the user, it's just an application running on a physical computer, but to an application running in a virtual machine, it looks like it's working on a real computer. [0003] Along with increasing server utilization and reducing enterprise server invest...
