Network Topology: looks like they use the ASR9006, and NLR is no more
For cost-savings reasons, the university's connectivity is primarily provided through an aggregation network shared by several other universities in Virginia, the [[Mid-Atlantic Research and Education Exchange]] (MREX). MREX is operated by Virginia Tech and provides connectivity for the [[Mid-Atlantic Research Infrastructure Alliance]] (MARIA), an alliance of the universities that receive connectivity through MREX.<ref>[http://www.marialliance.net/about-us]</ref>
MREX operates two regional hubs: MREX-ATL at Telx Atlanta and MREX-DC at Equinix Ashburn. MREX-DC was formerly the only regional hub, and was previously part of the predecessor to MARIA, the [[Mid-Atlantic Terascale Partnership]] (MATP). At each hub, MREX operates a Cisco ASR9000 series ASR9006 aggregation router.
At Equinix in [[Ashburn]], MREX-DC has a 100 Gigabit connection to [[Internet2]], 10 Gigabit connections to [[ESnet]] and the Equinix Internet Exchange, and 30 Gigabits of commodity Internet connectivity through Cogent.
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]] in Falls Church, there are is also a 10 Gigabit connections connection to [[National LambdaRail]] and [[Mid-Atlantic Crossroads]], as well as 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. MREX-ATL was opened in 2014 and is the first network facility operated by Virginia Tech located outside of Virginia.<ref>[http://www.cafm.vt.edu/busprac/_docs/bpseminar_2014/2014-BusinessPracticeSeminar-Internet.pdf]</ref>
