Problems solved by technology

[0003] At present, when building an Overlay network, to achieve intercommunication between servers, it is necessary to build a bidirectional Overlay tunnel between any two servers, and the number of tunnels is large; for example, if the Overlay network includes N servers, Then the number of Overlay tunnels in the Overlay network is N*(N-1) / 2. When a new server needs to be added in the Overlay network, it is necessary to establish a bidirectional Overlay tunnel between the new server and each existing server, and the steps are cumbersome.

Embodiment approach

[0086] It should be noted that, in this implementation mode, a one-way overlay tunnel is established between the forwarding device and the server, and the server only needs to have the ability to decapsulate, and the forwarding device encapsulates the network data generated by the server.

[0087] In a possible implementation manner, the destination IP address sent by the first server to the forwarding device through the first network device is the IP address of the virtual machine running on the second server, and when encapsulating network data based on the destination IP address , you can first determine the real IP address of the server corresponding to the virtual IP address (that is, the IP address of the server where the virtual machine corresponding to the destination IP address is located) from the comparison table between the pre-stored virtual IP address and the real IP address of the server, and then according to The determined real IP address encapsulates the netwo...

Abstract

The invention provides a data transmission method, device and system. The method comprises the steps of: receiving network data and a destination IP address sent by a first network device connected with a first server in a first network based on an IP address of a forwarding device, the destination IP address being an address in a second network, and the first network and the second network beingnetworks of different attributes; packaging the network data based on the destination IP address; and sending the packaged network data to a second server corresponding to the destination IP address,so that the second server de-encapsulates the encapsulated network data.

Description

technical field [0001] The present disclosure relates to the field of computer technology, in particular, to a data transmission method, device and system. Background technique [0002] The Overlay network is a virtualization technology model superimposed on the existing network architecture. Its general framework is to realize the bearer of applications on the network without large-scale modification of the basic network, and can be separated from other network services. [0003] At present, when building an Overlay network, to achieve intercommunication between servers, it is necessary to build a bidirectional Overlay tunnel between any two servers, and the number of tunnels is large; for example, if the Overlay network includes N servers, Then the number of Overlay tunnels in the Overlay network is N*(N-1) / 2. When a new server needs to be added in the Overlay network, it is necessary to establish a bidirectional Overlay tunnel between the new server and each existing serv...
