Phoebus

	Network cyberinfrastructure to improve end-to-end performance
	Uses adaptation points in the network to break TCP connections into a series of shorter connections

Phoebus

	How applications can use Phoebus
		Modified to call the Phoebus client library
		Use a transparent wrapper library to allow the application to use Phoebus without changes
		Have an adaptation point in the network proxy the applicationŐs TCP connections

Phoebus

	Why DCN?
		Circuits allow the use of better transport protocols than TCP over more of the end-to-end connection
		Dynamic circuits are a good fit for Phoebus due to the possibility of needing to connect to any of a wide variety of adaptation points.

Phoebus

	Converting our service to use DCN
		Current: Can allocate circuits effectively for short or known duration connections
			Required 2-3 days to enable our service to request circuits
		Future: Does not effectively handle arbitrary length connections
			Differences between the Phoebus model and the OSCARS model

Phoebus

	Sample Usage
		Being used regularly by a researcher at Syracuse University to retrieve data from the LIGO Project
	Deployment Plans
		Current Adaptation Points:
			Salt Lake City
			New York
		Expanding the Phoebus service to the all 9 POPs in the Internet2 network
