AMPATH: Pathway of the Americas International Exchange

Point:

AMPATH in Miami is providing CHEPREO's connectivity requirements to U.S. and non-U.S.

production and research networks.  Through AMPATH, CHEPREO members access the

Internet2 and National Lambda Rail (NLR) networks that interconnect large research projects,

such as collaborations involving FermiLab and the U.S. LHC Tier-2 and Tier-3 sites. For

network research and testbed applications, CHEPREO has access to the NSF funded UltraLight

network. The CHEPREO project provided the means to increase the network connection between

the U.S. and Brazil to an STM-4 (622Mbps) circuit.

The AMPATH facility in Miami interconnects international research and education networks to

facilitate the exchange of network information that carries international science research and

education information into and outside of the U.S. Located at the NAP (Network Access Point) of

the Americas, the AMPATH international exchange point is a collaborative effort, providing its

members with access to the Internet2 network; National Lambda Rail; Florida Lambda Rail; tier1

commodity Internet providers; collocation facilities; and Smart Hands services, for remote
