Ethernet private line connection system of cross-regional local area network

Abstract

The invention relates to an Ethernet private line connection system of a cross-regional local area network. The system comprises a headquarters local area network and a branch local area network connected with the headquarters local area network, the headquarters local area network comprises a data center, headquarters PE equipment and a VSI headquarters machine which are connected in sequence, wherein the head office PE device is connected with a head office encryption and decryption machine, the branch local area network comprises a branch server, a branch PE device and a VSI branch machinewhich are connected in sequence, the branch PE device is connected with a branch encryption and decryption machine, and the VSI head office machine is connected with the VSI branch machine through anoptical fiber network system. Compared with the prior art, according to the invention, the VPLS communication channel is protected by the user branch local area network through the encrypted communication channel; a safe and reliable communication channel is established by using an urban passive optical network system and an enterprise headquarters local area network, and the method has the advantages of low access cost, stable quality, high schedulable stability, low delay, large throughput, short opening time, capability of managing network of terminal equipment and the like.

Description

technical field [0001] The invention relates to the technical field of communication networks, in particular to an Ethernet dedicated line connection system for cross-regional local area networks. Background technique [0002] Traditional enterprises usually deploy applications (e-mail, file sharing, web applications, etc.) in the computer room of the enterprise headquarters, and connect the branch offices to the computer room of the headquarters by renting the operator's MPLS-VPN dedicated line. The operator promises the SLA (Service-Level Agreement) of the private line service to meet the needs of enterprises for deploying various applications in various branches. [0003] However, traditional Layer 2 private line networks such as MPLS-VPN, MSTP, and PTN have problems such as expensive lease fees, long deployment cycles, complex and time-consuming deployment of new services, and cannot meet the needs of fast provisioning and flexible deployment of enterprise networks. In ...

Problems solved by technology

[0003] However, traditional Layer 2 private line networks such as MPLS-VPN, MSTP, and PTN have problems such as expensive lease fees, long deployment cycles, complex and time-consuming deployment of new services, and cannot meet the needs of fast deployment and flexible deployment of enterprise networks.

In addition, due to the introduction of cloud computing, more enterprises migrate their application deployment to the cloud, causing a sharp increase in branch egress traffic, which further increases the cost of WAN networks for enterprises.

[0004] Enterprises try to connect branches and headquarters through the Internet. Enterprises lease Internet links (such as xPON, xDSL, LTE / 5G, etc.), but these lines are generally dynamic dial-up, and their ip addresses are not fixed. Enterprises connect through dial-up VPN To the headquarters, the management and deployment of this solution remain unchanged, the line service quality cannot be improved, and the short-term sudden traffic demand of the enterprise cannot be met in time
