Dedicated network line connection method and device

Abstract

An embodiment of the invention provides a dedicated network line connection method and device. The method comprises steps as follows: connecting a dedicated network line of a lead-out party to a connecting port of a server and creating dedicated network namespace for the dedicated network line of the lead-out party; creating a pair of virtual network cards including a first virtual network card and a second virtual network card to map the network namespace from a dedicated network line of a lead-in party to the dedicated network line of the lead-out party, adding the first virtual network cardto a virtual network of the network namespace; creating a first virtual network bridge for bridge connection of the connecting port and the second virtual network card to determine a second virtual network bridge of the server; and adding the network namespace to the dedicated network line of the lead-in party through the first virtual network card on the basis of the first virtual network bridgeand the second virtual network bridge. By means of the method and the device, the situation of conflict of network addresses is avoided, and use of dedicated hardware for connection is also avoided.

Description

technical field [0001] The invention relates to the technical field of computer networks, in particular to a method and device for network dedicated line connection. Background technique [0002] With the development of network technology, people's requirements for network access services are becoming more and more diverse. For example, due to business needs, a dedicated line network is often set up from one computer room, such as the M computer room, to another cooperative computer room, such as the N computer room, and communicates through this network. The characteristics of this type of dedicated line are that the traffic is relatively small, the business is complex, and there are many connecting parties, so the IP addresses may often conflict, and they need to be isolated from each other to ensure security. In the prior art, the following methods are usually used for connection to avoid IP address conflicts: [0003] A. Renegotiate or plan the IP address so that the I...

AI Technical Summary

Problems solved by technology

[0007] 1. The shortcomings of the above method A are obvious. For a long-term use and large-scale network, the cost of modifying IP and / or routing configuration is extremely high;

[0008] 2. The cost of the above method B is that the reachability of the internal network of the M party is partially destroyed, so that the function of the receiving program is limited. If party M also has a device with an IP of 10.1.1.1 that needs to communicate with the forwarding device, the program cannot access its own IP of 10.1.1.1;

[0009] 3. The problem with the above method C is that the required hardware costs are relatively high, and if you purchase dedicated router hardware, you may be limited by the software or license of the dedicated device;

[0010] 4. There is still a problem in the above method C, that is, there are certain difficulties in managing the devices that join the N-party network;

[0011] 5. The above methods B and C both have huge management problems, the overall network structure is complex, there are traps, and maintenance is difficult
