Interconnecting Spectrum Between Multiple Domains to Support Science Applications: A Use Case

Session Abstract

In 2015, two NSF IRNC proposals were awarded to evolve the U.S. to South America collaboration: AmLight-ExP (NSF Award#ACI-1451018) and AtlanticWave-SDX (NSF Award ACI#1451024). The Americas Lightpaths Express and Protect (AmLight ExP) project aims to implement a hybrid network strategy that combines the use of optical spectrum and leased capacity, to build a reliable, state-of-the-art network infrastructure for research and education. With spectrum available between the U.S. and South America, researchers and network operators will have new possibilities for connectivity and experimentation, including easy access to capacity expansion. This drives the question, is it possible to interconnect distinct optical networks to provide cost effective, continuous, usable optical spectrum for research? The AtlanticWave-SDX project in coordination with Florida LambdaRail (FLR) will attempt to test this premise across the FLR optical network.

With AmLight-EXP and AtlanticWave-SDX projects, FIU/AMPATH will need to interconnect and operate optical spectrum coming from three different operators: the submarine operator connecting its landing station in Boca Raton to Brazil; the local operator connecting Boca Raton to Miami and, FLR, that connects Miami to Jacksonville. From the submarine operator, AmLight-EXP will receive 300GHz. From the local provider between Boca Raton and Miami, more than 1THz will be available. Potentially at FLR, 250GHz, using diverse paths will be provided.

Interconnecting optical domains brings a significant set of challenges and concerns to be addressed. Is end to end optical across optical domains possible without “domain-based” regeneration? How can spectral width and frequency requirements be coordinated? How can channels be modeled and supported across domains with varying optical power and signal to noise requirements. Can super-channel capabilities be leveraged? How will failure scenarios be handled? Can the interconnected optical networks be protected from one another? There are obviously many others as well.

For the past 18 months, FLR, in collaboration with FIU/AMPATH, has been conducting optical experimentation to support a 100G alien wave between Miami and Jacksonville. The knowledge acquired to support this 100G alien wave will be used in the next challenge. To provide projects such as the LSST with immediate capacity, FIU/AMPATH and FLR will start with lit waves which will largely be domain based. As the above questions are answered, milestones accomplished, and technologies/techniques developed in cooperation with vendors, domains will be interconnected, and unnecessary regeneration will be removed. This will provide the most flexible, highest capacity, and most cost effective network resource possible for research and education. This proposal aims to present to Internet2 Technology Exchange audience all challenges to be faced by FIU/AMPATH, FLR and the optical vendors to achieve these stated goals.
