Traditionally, WAN and campus networks and services have evolved independently from each
other. For example, MPLS traffic engineered and VPN technologies have been targeted towards the
WAN, while the LAN (or last mile) implementations have not incorporated that functionality. These
restrictions have resulted in dissonance in services offered in the WAN vs. the LAN. While
OSCARS/NSI virtual circuits are widely deployed in the WAN, they typically only run from site
boundary to site boundary, and require painful phone calls, manual configuration, and resource allocation
decisions for last mile extension. Such inconsistencies in campus infrastructures, all the way from the
campus edge to the data-transfer hosts, often lead to unpredictable application performance. New
architectures such as the Science DMZ have been successful in simplifying the variance, but the Science
DMZ is not designed or able to solve the end-to-end orchestration problem. With the advent of SDN, the
R&E community has an opportunity to genuinely orchestrate end-to-end services - and not just from a
network perspective, but also from an end-host perspective. In addition, with SDN, the opportunity exists
to create a broader set of custom intelligent services that are targeted towards specific science application
use-cases. This project motivates an advanced deployment of SDN equipment and creation of a
comprehensive SDN software platform that will help with bring together the missing end-to-end story.
