Increasing need for people to be " connected " ; while at the same time remain as mobile as ever poses several interesting issues in wireless networks. It is conceivable in the near-future that wireless " hotspots " experience flash crowds-like traffic arrival pattern. A common phenomena in the Internet today characterized by sudden and unpre-dicted(More)
Future vehicular networks are expected to deploy short-range communication technology for inter-vehicle communication. In addition to vehicle-to-vehicle communication, users will be interested in accessing the multimedia-rich Internet from within the vehicular network. This motivates a compelling application of Co-operative Networking in the Vehicular(More)
Microsoft is producing high-quality documentation for Windows client-server and server-server protocols. Our group in the Windows organization is responsible for verifying the documentation to ensure it is of the highest quality. We are applying various test-driven methods including, when appropriate, a model-based approach. This paper describes certain(More)
The problem of estimating the capacity of an Internet path is one of fundamental importance. Due to the multitude of potential applications, a large number of solutions have been proposed and evaluated. The proposed solutions so far have been successful in partially addressing the problem, but have suffered from being slow, obtrusive or inaccurate. In this(More)
splitting the connection. This paper takes this approach one step further by exploring the use of a TCP proxy on board a satellite for the purpose of enhancing end-to-end TCP performance. We will show this approach yields a number of important advantages, especially for small, mobile terminals, multi-segment systems, and multicast applications. As part of(More)
—TCP performance can be significantly affected when the buffer capacity at the routers is small. This is possible either because many flows share the network or that the bandwidth-delay product is large (e.g. satellite links). The behavior of various versions of TCP with respect to buffer capacity issues has not been studied in much detail. In this paper,(More)
Peer-Peer (P2P) technologies have recently been in the limelight for their disruptive power in particular they have emerged as a powerful multimedia content distribution mechanism. However, the widespread deployment of P2P networks are hindered by several issues, especially the ones that influence end-user satisfaction, including reliability. In this paper,(More)
Grido is an architecture that targets a network operator intending to provide enhanced services to its customers. This is achieved by setting up a " backbone " overlay network. A backbone overlay is a set of Internet hosts dedicated to providing overlay services. A network operator can view Grido as a sandbox for rapid prototyping and market adoption(More)
