Bill's Johnston's slides show a clear evolution of the SDN infrastructure with multiple wavelengths on various legs of the Internet2/NewNet footprint. Details subject to funding and loading experience. OSCARs will be used to define paths across this increasingly rich infrastructure.
Change from 10 to 100 Gbps wavelengths estimated to occur in the
2010-2011 timeframe. Support for T2 - T1 connections possible, and compatible with ESnet AUP which is "one end must be a DOE facility".
