Network Topology
At another MREX-DC facility in McLean, connected as part of a fiber ring that includes the [[Arlington Research Center]] and the [[Northern Virginia Center]], there is also a 10 Gigabit connection to [[Mid-Atlantic Crossroads]] and a 1 Gigabit connection to [[NetworkVirginia]].
At Telx in Atlanta, MREX-ATL has 10 Gigabit connections to [[Southern Crossroads]], [[ESnet]], the Telia Internet Exchange, and 30 Gigabits of commodity Internet connectivity through Telia. <ref>[http://www.cafm.vt.edu/busprac/_docs/bpseminar_2014/2014-BusinessPracticeSeminar-Internet.pdf]</ref> MREX-ATL was opened in 2014 and is the first network facility operated by Virginia Tech located outside of Virginia.<ref>[httphttps://www.cafmvtnews.vt.edu/buspracarticles/_docs2014/bpseminar_201403/2014032114-BusinessPracticeSeminarit-Internetdatanetworkexchange.pdfhtml]</ref>
From the Andrews Information Systems Building, there are redundant fiber connections to the main campus at both [[Burruss Hall]] and [[Cassell Colliseum]]. [[Owens Hall]], [[Hillcrest Hall]], and [[Shanks Hall]] have intermediate routers for some buildings. Nearly all ethernet portals on campus are capable of 100 Mbps or Gigabit speeds, due to fiber interconnects between buildings; however, intrabuilding wiring varies in age and may not support high speeds. The vast majority of campus IPv4s come from two directly-allocated blocks (128.173.0.0/16 and 198.82.0.0/16).
