The embodiment of the invention discloses a cross-network communication method, used for not modifying routing configuration of an IDC whole network, completing cross-network data communication, and reducing the cost in a cross-IDC communication process. The method comprises the following steps: a first proxy server receives first data sent by a first data server; the first data includes first source addresses and first destination addresses; the first source addresses are an internal network IP address and a port address of the first data server; the first destination addresses are an internal network IP address and a port address of the first proxy server; the first proxy server converts the first data including the first source addresses and the first destination addresses into second data including second source addresses and second destination addresses through a pre-set proxy rule; the second source addresses are an internal network IP address and a port address of the first proxy server; the second destination addresses are an internal network IP address and a port address of a second proxy server; and the first proxy server sends the second data to the second proxy server.
Description
technical field [0001] The invention relates to the communication field, in particular to a cross-network communication method and a proxy server. Background technique [0002] In the prior art, data servers located in different Internet Data Centers (Internet Data Center, IDC) usually use a virtual private network (Virtual Private Network, VPN) to perform intranet communication. That is, two (or more) IDC computer rooms communicate with each other on the intranet. Usually, a VPN gateway is deployed at the IDC exit. Each VPN gateway is configured with a VPN tunnel to achieve mutual communication. Configure a routing policy on each IDC (the destination address is the Internet Protocol (IP) data packets going to other IDC intranet networks, and go out through the VPN gateway). [0003] For a large IDC computer room, the internal network usually runs a dynamic routing protocol, and the routing configuration change is fully communicated to the entire IDC network, and the IP dat...
