DRAGON Objectives• Experiment with next generation regional

optical network architectures, features, capabilities

• Experiment with eScience applications– What network features and capabilities are

needed to support eScience applications?– What features do eScience applications need

to include, to best utilize next generation networks?

– Build collaborations between network community and eScience communitieso to utilize next generation networks to

enable advanced science in those domains

DRAGON Activities• Instantiation of an Experimental Regional Optical

Network in Washington D.C. region– “Hybrid” Packet Switched and Circuit Switched

Infrastructure– All optical core– Protocol agnostic (HDTV, ethernet, sonet, fibreChannel,

any optical signal)– Dynamic provisioning of end-to-end paths– Inter-Domain– Authentication, Authorization, Accounting– Scheduling

• Integrate eScience applications– eVLBI– High Definition format collaboration and remote

steering/display of visualization resources

End to End GMPLS TransportWhat is missing?

DRAGON Architecture Components

• Network Aware Resource Broker (NARB)– Inter-domain routing for GMPLS TE Capabilities– IGP/EGP Listener– Path Computation– AAA– Scheduling (and monitoring/enforcement)– Application Request Processing

• Virtual Label Switched Router (VLSR)– Proxy for non-GMPLS capable network segments

• Application Specific Topology Descriptions Language (ASTDL)– Language for application requests to network

• All Optical End-to-End Routing

Commercial PartnerMovaz Networks

• MEMS-based switching fabric• 400 x 400 wavelength switching, scalable to 1000s x 1000s • 9.23"x7.47"x3.28" in size • Integrated multiplexing and demultiplexing, eliminating the cost and

challenge of complex fiber management

• Dynamic power equalization (<1 dB uniformity), eliminating the need for expensive external equalizers

• Ingress and egress fiber channel monitoring outputs to provide sub-microsecond monitoring of channel performance using the OPM

• Switch times < 5ms

Low latency High Definition CollaborationDRAGON Enabled

• End-to-end native SMPTE 292M transport• Media devices are directly integrated into the DRAGON environment via proxy hosts

– Register the media device (camera, display, …)– Sink and source signaling protocols– Provide Authentication, authorization and accounting.

Low Latency Visual Area Networking

• Directly share output of visualization systems across high performance networks.• DRAGON allows minimum latency paths.
