Virtual private network impacts on the computer network performance with different traffic generators

Virtual Private Network Design Under Traffic Uncertainty

We propose different formulations as well as efficient solution approaches for the VPN design problem under traffic uncertainty with symmetric bandwidths.

Virtual private network bandwidth management with traffic prediction

Dynamic link resizing is an attractive approach for resource management in virtual private networks (VPNs) serving modern real-time and multimedia traffic. In this paper, we assess the use of linear traffic predictors to dynamically resize the bandwidth of VPN links. We present the results of performance comparisons of three predictors: Gaussian, autoregressive moving average (ARMA) and fractio...

Exploring Traffic Pricing for the Virtual Private Network

This paper presents a virtual private network traffic pricing model with first-in-first-out and round-robin bandwidth scheduling. A transaction-level pricing architecture based on proxy server technology is proposed for the implementation. The experiment us ing real-time test data shows that the pricing mechanism can effectively improve a VPN's transmission efficiency measured in the service we...

Performance Impact of Data Compression on Virtual Private Network Transactions

Virtual private networks (VPNs) allow two or more parties to communicate securely over a public network. Using cryptographic algorithms and protocols, VPNs provide security services such as confidentiality, host authentication and data integrity. The computation required to provide adequate security, however, can significantly degrade performance. In this paper, we characterize the extent to wh...
