Interurban virtual private line control device based on GRE routing encapsulation

Abstract

The invention relates to an interurban virtual private line control device based on GRE routing encapsulation. The interurban virtual private line control device comprises a first city data center, a second city data center, a GRE tunnel, a first city encryption and decryption security authentication device, a second city encryption and decryption security authentication device and the internet, wherein the first city data center is connected with the second city data center through the GRE tunnel and the internet respectively, the first city data center is connected with the first city encryption and decryption security authentication device, and the second city data center is connected with the second city encryption and decryption security authentication device. Compared with the prior art, the interurban virtual private line control device has the advantages of bringing benefit for enterprise users, providing low cost services for users and the like.

Description

technical field [0001] The invention relates to a virtual private line control device between cities, in particular to a virtual private line control device between cities based on GRE routing encapsulation. Background technique [0002] At present, there is a large amount of data transmission demand between Shanghai and Hong Kong. Through traditional Internet transmission, it is impossible to bypass the congested node between mainland China and Hong Kong. The delay often increases, the packet loss is serious, and the jitter is large, which affects the quality of users. Key overseas and international-oriented applications, such as ERP, CRM, mail sending and receiving, etc., and users face few choices, can only use traditional MPLS VPN, IPLC, SDH and other expensive P2P dedicated line access solutions, resulting in cost Too high and other deficiencies cannot be promoted and applied. Contents of the invention [0003] The purpose of the present invention is to overcome the ...
