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

Managing and utilizing storage resources have resulted in complexity because of the heterogeneous nature of storage infrastructures. Paper elucidates that Virtual Private Network created in the Wireless Public Network would have implemented virtualization and would result in enhancement of productivity and efficient management of storage infrastructures. Proof is generated that Virtual environm...

The paper describes an architecture allowing Mobile IP hosts to access to a virtual private network that is protected by a firewall from the public Internet. The implementation based on adaptation of standard protocols (IPSec and Mobile IP) and initial performance results are discussed.
