DESCRIPTION:The operational challenges posed in enterprise networks\, pres
 ent an appealing opportunity for the software-defined orchestration of the
  network (SDN). However\, the primary challenge to realizing solutions bui
 lt on SDN in the enterprise is the deployment problem. Unlike in the datac
 enter\, network upgrades in the enterprise start with the existing deploym
 ent and are particularly budget and resource-constrained. In this work\, w
 e investigate the prospect for partial Software Defined Network deployment
 . We present Panopticon\, an architecture and methodology for planning and
  operating networks that combine legacy and upgraded SDN switches. Panopti
 con exposes an abstraction of a fully-deployed SDN in a partially upgraded
  legacy network\, where the SDN benefits extend potentially over the entir
 e network. We evaluate the feasibility of our approach through simulation 
 on real enterprise campus network topologies entailing over 1500 switches 
 and routers. Our results suggest that with only a handful of upgraded swit
 ches\, it becomes possible to operate most of an enterprise network as a s
 ingle SDN while meeting key resource constraints.
