Load Balancing for the Numerical Solution of the Navier-Stokes Equations

This paper simulates the performance of a load balancing scheme. In particular, it studies the application of the Extrapolated DiFfusion EDF method for the efficient parallelization of a simple 'atmospheric' model, which involves the numerical solution of the steady state Navier-Stokes NS equations in the horizontal plane and random load...

TFRC Veno: An Enhancement of TCP Friendly Rate Control Over Wired/Wireless Networks

TFRC is a TCP-Friendly Rate Control protocol based on TCP Reno's throughput equation. It is designed to provide optimal service for unicast multimedia flow operating in the wired Internet environment. However, in wireless networks, TFRC, same as TCP Reno, suffers significant performance degradation. This paper proposes to make use of...

Analytical Characterization of the Throughput of a Split TCP Connection

The idea of implementing a single logical end-to-end connection as a series of cascaded transport connections is introduced and argues that there are several potential advantages to doing so. One possible advantage investigated in this paper is improved throughput via pipeline parallelism. An equation is developed for the throughput of...
