Southern Crossroads SoX: Serving the research and education arena in the Southeast region of the United States.


The Software Defined Exchange (SDX) applies the principles of Software Defined Networking to the Internet Exchange to overcome long standing limitations in inter-domain routing. The goal is to provide a rich set of options for specifying policy at the exchange point to describe how traffic is handled between network operators. SoX is participating in several SDX related projects including a regional SDX deployment for the Global Environment for Network Innovation (GENI). Georgia Tech and SoX were awarded the NSF ACI-1451024 project called “AtlanticWave-Software Defined Exchange: A Distributed Intercontinental Experimental Software Defined Exchange (AtlanticWave-SDX)” which is comprised of two components: (1) a network infrastructure development component to bridge 100G of network capacity between Research and Education backbone networks in the U.S. and South America; and (2) an innovation component to build a distributed intercontinental experimental SDX between the U.S. and South America, by leveraging open exchange point resources at SoX (Atlanta), AMPATH (Miami), and Southern Light (São Paulo, Brazil).
