Multipath transport is an important way to improve the transmission performance of Internet applications. This demo presents a multipath transport system based on application level relay (MPTS-AR), which defines three kinds of logical entity of user agent, controller and relay server. Controller and relay server collaboratively provide relay services, and user agent integrates the multipath transmission...
IP traceback can be used to find the origins and paths of attacking traffic. However, so far, no Internet-level IP traceback system has ever been deployed because of deployment difficulties. In this paper, we present an easily-deployable light-weight IP traceback based on flow (EasyTrace). In EasyTrace, it is not necessary to deploy any dedicated traceback software and hardware at routers, and an...
In this paper we present a uniform negotiation and delivery framework for TCP-based data collaboration applications over IP network. With this framework rich innovative collaboration services can be developed conveniently and provide users with novel communication experience. The framework adopts the offer/answer model with extended Session Description Protocol as session description and negotiation...
Virtual machines have emerged as an attractive approach for utility computing platforms because applications running on VMs are fault- and security- isolated from each other, yet can share physical machines. An important property of a virtualized utility computing platform is how quickly it can react to changing demand. We refer to the capability of a utility computing platform to quickly reassign...
