Embodiment 1

[0079] refer to figure 1 , is a schematic diagram of networking of a system implementing network interconnection provided in Embodiment 1 of the present application. The system includes a first server and a first proxy server both deployed in a first data center, a second server and a second proxy server both deployed in a second data center.

[0080] The first server is configured to send the data packet to the second server.

[0081] Wherein, the data packet sent by the first server to the second server may be a data packet based on the TCP protocol or a data packet based on the UDP protocol. Wherein, the TCP protocol is a connection-oriented protocol, so the first server may first send a data packet for requesting to establish a TCP connection to the second server, and after determining that the TCP connection is successfully established, send a packet carrying a packet based on the established TCP connection to the second server. A data packet with user data information;...

Embodiment 2

[0135] In combination with the system for realizing network interconnection described in the first embodiment above, embodiment 2 of the present application provides a method for realizing network interconnection. For details, please refer to figure 2 The flow chart of the method is shown:

[0136] Step 201: The first proxy server receives a data packet sent by the first server deployed in the first data center to the second server deployed in the second data center through routing and forwarding, and the packet header of the data packet includes a 5-tuple.

[0137] Step 202: the first proxy server modifies the source address in the 5-tuple of the data packet to the address of the first proxy server, and modifies the destination address to the address of the second proxy server.

[0138] Step 203: the first proxy server sends the modified data packet to the second proxy server deployed in the second data center.

[0139] Step 204: the second proxy server restores the five-tu...

Embodiment 3

[0226] Such as Figure 7 As shown, it is a schematic structural diagram of a device for implementing network interconnection provided by Embodiment 3 of the present application, including:

[0227] The receiving module 71 is configured to receive a data packet sent by the first server deployed in the first data center to the second server deployed in the second data center through routing and forwarding, and the packet header of the data packet includes a quintuple;

[0228] A processing module 72, configured to modify the source address in the quintuple of the data packet to the address of the first proxy server, and modify the destination address to the address of the second proxy server;

[0229] A sending module 73, configured to send the modified data packet to the second proxy server deployed in the second data center.

Abstract

The invention relates to the communication technology field, especially relates to a system, a method, and a device of realizing network interconnection. The problems of the prior art such as poor transmission performance and low bandwidth utilization rate of trans-WAN interconnection of a data center. The method comprises steps that a data packet, which is transmitted by a first server deployed a first data center to a second server deployed on a second data center, and is forwarded by a router, is received, and the header of the data packet comprises a quintuple; the source address of the quintuple of the data packet is modified to an address of a first proxy, and the target address is modified to an address of a second proxy; the modified data packet is transmitted to the second proxy deployed on the second data center, and the quintuple of the modified data packet is reduced by the second proxy into the quintuple before the modification, and the reduced data packet is transmitted to the second server, and the second server is used to respond to the reduced data packet.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a system, method and device for realizing network interconnection. Background technique [0002] With more and more distributed network construction, the network construction between enterprises and company headquarters is becoming more and more perfect. ) Internet is also facing many problems. [0003] At present, there are mainly two types of inter-wide-area network interconnection methods that are relatively popular: leased line and virtual private network (Virtual Private Network, VPN). Dedicated lines mainly include Digital Data Network (DDN), Synchronous Digital Hierarchy (SDH), etc. Their advantages are mainly reflected in high transmission quality, short delay, and high speed. However, due to the relatively high construction cost of large-scale cross-regional leased lines, it is not suitable for enterprises. VPN is mainly to set up communication li...
