Technical field
The present invention relates to Internet technical fields, more particularly to a kind of across Intranet communication means and device.
Background technique
Cloud computing technology is warmly pursued by enterprise at present, and various Cloud Server manufacturers emerge one after another, but each factory
Quotient Cloud Server data center distribution be all it is different, can not accomplish the whole world it is each area deployment data center.Such as one
Organization network disposes data center, the two with emphasis on go up north broadly area's deployment data center, another organization network emphasis in overseas
It can not efficient communication.Transnational enterprise generally buy at home some manufacturer offer Cloud Server, foreign procurement another
The Cloud Server that manufacturer provides, the data of Liang Jia cloud manufacturer cannot achieve intercommunication, i.e., can communicate but because of transnational data
The particularity effect of transmission is often barely satisfactory.
By taking cloud node server data interchange as an example, the prior art is usually to use ipsec mode, different cloud services
Device establishes the channel Virtual Private Network (Virtual Private Network, VPN), to realize data interchange.The prior art
It has the following disadvantages:
(1) every Cloud Server can only establish the channel VPN, i.e., can only realize 1 pair 1 of data interchange, can not achieve 1
To N.
(2) the VPN Path Setup of virtual machine and server is completed, and transnational transmission is since link is long, data transmission effect
Fruit is poor.
