A data transmission system and method across IDC

Abstract

The invention discloses a cross-IDC data transmission system, which includes a producer server, a consumer server, a local IDC forwarding server, a remote IDC forwarding server, a local router, and a remote router; the information sent by the producer server is converted into data through the local router After the packet is sent to the local IDC forwarding server, the local IDC forwarding server uses the uio mechanism to rewrite the header of the data packet and then sends it to the remote IDC forwarding server through the WAN. The remote IDC forwarding server restores the data of the data packet according to the local comparison information and then sends to the consumer server. A data transmission method across IDCs is also provided.

Description

technical field [0001] The present invention relates to the technical field of Internet data processing, in particular to a cross-IDC data transmission system and method, that is, to perform information interaction between a local Internet Data Center (IDC, Internet Data Center) and a remote Internet Data Center. Background technique [0002] A large number of message interactions are required between data sources and data sinks (local IDCs and remote IDCs). Therefore, information interaction services need to be established to provide information exchange channels between different service applications and ensure real-time data on both sides. [0003] Existing technical scheme has following several kinds: [0004] 1. Directly establish connections for different services and perform data synchronization respectively. [0005] 2. Establish a proxy service to process data in a unified manner. [0006] The deficiencies that exist in prior art are: [0007] Solution 1 needs to...

AI Technical Summary

Problems solved by technology

[0007] Solution 1 needs to establish a large number of connections, which is inconvenient to manage. When performing cross-IDC transmission, a large number of servers need to be exposed to the external network, which is inconvenient to maintain. When one party’s service changes, the other party needs to be adjusted accordingly, which has poor adaptability

[0008] Option 2 establishes a proxy service, which increases flexibility and reduces the risk of servers being directly exposed to the public network, but requires proxy server clusters to ensure service availability, which greatly increases service costs
