" Web 2.0 " and " cloud computing " are revolutionizing the way IT infrastructure is accessed and managed. Web 2.0 technologies such as blogs, wikis and social networking platforms provide Internet users with easier mechanisms to produce Web content and to interact with each other. Cloud computing technologies are aimed at running applications as services(More)
The widespread use of sequential simulation in large scale parameter studies means that large cost savings can be made by improving the performance of these simulators. Sequential discrete event simulation systems usually employ a central event list to manage future events. This is a priority queue ordered by event timestamps. Many different priority queue(More)
In the past several years, online social networks (OSNs) such as Facebook and MySpace have become extremely popular with Internet users. Such sites are popular with users because they simplify both communication among "communities" and access to applications. Application developers are attracted to these sites also, as they are able to exploit(More)
This paper explains how DiffServ has been implemented in an IP network simulator using an asynchronous conservative parallel discrete event simulation (PDES) kernel. DiffServ provides Quality of Service (QoS) functionality for IP networks and is designed to provide greater scalability and lower overhead than previous IP based QoS schemes. The paper explains(More)
