Performance Investigation of Virtual Private Networks with Different Bandwidth Allocations

Mahalakshmi Chidambara Natarajan, Ramaswamy Muthiah, Alamelu Nachiappan

摘要:

虚拟专用网络(VPN)通过可公开访问的共享网络提供专用网络连接。VPN的带宽的有效分配在当前情况下由于变化的流量而具有重要意义。每个VPN端点都指定了它随时可能发送或接收的流量总量的界限。网络提供商定制VPN,以便有足够的带宽用于与这些界限一致的任何流量矩阵。该方法采用了Ad-hoc按需距离矢量(AODV)协议的使用,以期实现在移动网络的性能增强。基于NS 2的仿真结果进行评估,其指标为不同的带宽分配,除了分析其在紧急情况下,如链路故障的性能。结果突出了所提出的策略在实时的应用中的适用性。

英文摘要:

A Virtual Private Network (VPN) provides private network connections over a publicly accessible shared network. The effective allocation of bandwidth for VPNs assumes significance in the present scenario due to varied traffic. Each VPN endpoint specifies bounds on the total amount of traffic that it is likely to send or receive at any time. The network provider tailors the VPN so that there is sufficient bandwidth for any traffic matrix that is consistent with these bounds. The approach incorporates the use of Ad-hoc On demand Distance Vector (AODV) protocol, with a view to accomplish an enhancement in the performance of the mobile networks. The NS2 based simulation results are evaluated in terms of its metrics for different bandwidth allocations, besides analyzing its performance in the event of exigencies such as link failures. The results highlight the suitability of the proposed strategy in the context of real time applications.
