A Multi Access VPDN Network Model

VPN network is widely used at present, among which L2TP VPDN can better solve the problem of decentralized users accessing private networks, but users accessing through a variety of network types and multiple ISP will have higher time prices and occupy more bandwidth resources. Aiming at these drawbacks, a multi access L2TP VPDN network model named ILP is proposed, which has the characteristics of security and low cost. The simulation experiment of the new model is carried out, and the experimental results are analyzed by Waxman mathematical model, which shows that the results of the network simulation experiment are excellent. Finally, according to ILP model, the actual network is constructed, and all parameters operate normally.
