403	<h1>Advanced Networking</h1>
404	<p>The Advanced Networking group at Pittsburgh Supercomputing Center conducts research on network performance and analysis in support of high-performance computing applications. We also develop software to support heterogeneous distributed supercomputing applications and to implement high-speed interfaces to archival and mass storage systems.</p>
405	<p>Our researchers focus on such areas as TCP implementations, tools to tune TCP for better performance and software to monitor and improve network performance. In addition to our own research, PSC networking experts participate in national networking research efforts such as <a href="/web10G.org/">Web10G</a> and Net100.</p>
406	<h2>Three Rivers Optical Exchange</h2>
407	<p><a href="http://www.3rox.net/">Three Rivers Optical Exchange</a> is a regional network aggregation point providing high speed commodity and research network access to sites in western and central Pennsylvania. The primary focus for the Exchange staff is providing cost effective, high capacity, state-of-the-art network connectivity to the university community. They also provide well defined network services to both community (K-12, government) and commercial entities in western Pennsylvania.</p>
408	<p>Information on network status, architecture, outages, maintenance schedules and routing updates is included on the <a href="http://www.3rox.net/">Three Rivers Optical Exchange site</a>.</p>
409	<h2>Web10G</h2>
410	<p>Web10G is working to provide an instrumented implementation of TCP as part of standard Linux. This implementation will expose TCP's hidden machinery and allow any interested user to "look under the hood" and see how TCP actually functions under normal network use. It promises innovations in performance, stability, optimization, and network diagnostics to anyone who wants to fully exploit modern high bandwidth connections. Web10G offers users, developers, and network engineers the tools to diagnose and correct hidden network issues.</p>
411	<p>Join the Web10G team on our <a href="htps://lists.psc.edu/mailman/listinfo/web10g-user">mailing list</a>, view our<a href="https://lists.psc.edu/pipermail/web10g-user/"> archives</a> and visit the <a href="http://www.web10g.org">Web10G website</a>!</p>
