Experimental Networks
• Experimental networks are required to solve many
e-Science problems
• Experiments will be driven by Grand Challenge
Applications
– vantage point is the end-user
– application performance is the success indicator
• International connections required for multi-national
e-science projects and programs
• Collaboration across disciplines a hallmark
• Systemic approaches to solve networking issues

Experimental Network Characteristics
• Quality of Service
• Dedicated Provisioning for guaranteed data rates
• Support of other network layers such as GMPLS
and OBGP
• Repeatable network experiments
• Reconfigurability
• Experimental protocols and approaches for high
throughput, low latency, large bursts
• End-to-End performance and support

International Participation
• Coordination of advanced networking research activities
and programs, including research production networks
• Support of Grand Challenge applications which transcend
geographic and national boundaries
• Direct connections to the NSF Experimental Networks
– multiple projects and connections
– some problems can only be resolved by international partnerships
• Joint strategic planning efforts for longer term support of
e-Science and research

MAGIC
(Middleware And Grid Infrastructure Coordination)
• Coordinates Interagency Grid and Middleware efforts
–
DOE, NASA, NIH, NSF, NIST, NOAA, DARPA
• Enhances and encourages interoperable Grid and
Middleware domains
• Promotes usable, widely deployed middleware tools and
services
• Provides a Federal voice for effective international
coordination of Grid and Middleware Technologies
eVLBI
13
Magic Status
• Established by LSN in February
• Started meeting in next meeting May
• Persistence and support of middleware identified
as a critical immediate need
• Heighten awareness of Open Source licensing
among federal agencies
• Conduct a workshop in early August; develop a
“blue book” document
