Optimized Approach for Provisioning VPN in the Hose Model With QoS
Virtual private networks provide an encrypted connection between a user's distributed sites over a public network. Existing studies on quality of service deals with bandwidth in hose model. In this paper an Enhanced Hose model is used to specify the bandwidth and link utilization between the end points. The authors introduce a VPN tree algorithm (KDSVT) that is capable of computing all possible cost and link utilization of VPN Tree. Based on this algorithm, the authors introduce a novel algorithm that can achieve a cost optimized and link utilization VPN tree (KCDVT) with low average computational complexity.
