Implementation and Evaluation of Late Data Choice for TCP in Linux: Real-time delivery of time-dependent data over the Internet is challenging. UDP has often been used to transport data in a timely manner, but its lack of congestion control is often criticized. This criticism is a reason that the vast majority of applications today use TCP. The downside of this is...; Tags: Linux, Congestion, TCP, UDP, Tcp/Ip, Networking; White papers 2007-09-11

On Class-Based Isolation of udp, Short-Lived and Long-Lived TCP Flows: The congestion control mechanisms of TCP make it vulnerable in an environment where flows with different congestion sensitivity compete for scarce resources. With the increasing amount of unresponsive UDP traffic in today's Internet, new mechanisms are needed to enforce fairness in the core of the network. This paper proposes a...; Tags: TCP, UDP, Tcp/Ip, Networking; White papers 2007-01-01
Video to Go: The Effects of Mobility on Streaming Media in a CDMA2000 1xEV-DO Network: This paper experimentally examines the performance of streaming media applications over a CDMA2000 1xEVDO network. The performance of streaming in a cellular network is tested across three different levels of mobility, two applications, and the two transport layer protocols, TCP and UDP. Findings of this study are that streaming applications...; Tags: University Of Calgary, Mobility, Video, UDP, Streaming Media, Web Site Development, Web Technology, Tcp/Ip, Corporate Communications, Digital Media, Networking, Internet, Marketing, Consumer Electronics, Personal Technology; White papers 2007-01-01
Translating Scalable Video Streams From Wide-Area to Access Networks: Transmitting video over UDP has been considered advantageous because it allows for discarding of packets in favor of retransmissions, and sender-controlled timing. Using UDP has been criticized because it allows video streams to consume more than their fair share of bandwidth, which is typically associated with the back-off behavior of...; Tags: Microsoft Access, Network, TCP, Video, UDP, Video Stream, Tcp/Ip, Corporate Communications, Networking, Digital Video, Marketing, Personal Technology; White papers 2007-01-01
Lossy Bulk Synchronous Parallel Processing Model for Very Large Scale Grids: The performance of a parallel algorithm in a very large scale grid is significantly influenced by the underlying Internet protocols and inter-connectivity.
