This paper describes an efficient way to implement managed bandwidth services. The proposed solution is based on MPLS technology and especially with the creation of virtual private networks. The virtual private networks will be layer 3 VPNs (IP VPNs) and are described all the mechanisms and the MPLS features that are necessary for the MBS service implementation. The paper also describes how the...

In this article we describe recent work done in building a university-wide grid at the University of Cambridge based on the Condor middleware [1]. Once the issues of stakeholder concerns (e.g. security policies) and technical problems (e.g. firewalls and private IP addresses) have been taken into account, a solution based on two separate Condor environments was decided on. The first of these is...

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 local broadband provider Streamyx has imposed an in admitted practice of line throttling. As the result it affects the speed of BitTorrent download. To overcome the issue a procedure is to be found. Based on the fact that VPN is normally untouched by most ISP hence this technology is explored to be deployed on BitTorrent. Subsequently in this part of the article a further observation and an...
