Embodiment Construction

[0025] The so-called load balancing includes tunnel load sharing and session load sharing. According to different TunnelIDs or SessionIDs, L2TP control packets and data packets are sent to different tunnel boards for processing. Control packets and data packets under the same TunnelID or SessionID are sent to the same tunnel board for processing.

[0026] The following describes the processing of the tunnel control message.

[0027] There is no TunnelID in the tunnel control message (SCCRQ) message (TunnelID=0 in the message), and the tunnel distribution module in the interface board should implement the load balancing of the message to different LNS tunnel plate;

[0028] As the algorithm basis for the tunnel allocation module to realize load balancing, when the LNS device sets the IP address and binds the tunnel board, it needs to create the following configuration table (Tunnel balance table) for all the tunnel allocation modules:

[0029] Among them, the bound tunnel boa...

Abstract

The invention provides a network server, comprising plural tunnel plates and interface plate, where the interface plate comprises a tunnel distributing module, dividing these tunnel plates into plural groups, and distributing a corresponding IP address to each tunnel plate group, and simultaneously, being able to mark weight value of each tunnel plate according to the current tunnel or conversation load to establish tunnel or conversation according to the weight value. According to the weight, it uniformly distributes tunnels/messages to plural tunnel plates, which are united to the outside and implement internal user load balance of network server, thus saving addresses, simplifying networking and fully using system resources.

Description

technical field [0001] The invention relates to a network server for a private private network and a method for establishing a tunnel thereon. Background technique [0002] Private private networks built using public networks are called VPNs (Virtual Private Networks). VPNs built on these public networks provide security, reliability and manageability like current enterprise private networks. The traditional networking method is realized through remote dial-up connection, so it is also called VPDN (Virtual Private Dial-Up Network). The development of VPDN business can enable enterprises to connect their remote offices and travel staff at a significantly lower cost and business partners. With the current increasing number of mobile offices, the market demand for VPDN services is becoming increasingly urgent. [0003] The structure of a typical VDPN service constructed by L2TP (Layer 2 Tunneling Protocol) is as follows: figure 1 shown. Among them, LAC (L2TP Access Concentr...
