How do the pieces fit?
• We know how to build operational dynamic services using IDC protocol
(which is widely deployed, but not a standard)
• We know how to build operational performance services using
perfSONAR protocol (which is widely deployed and nearly a standard)
• OGF NSI WG is developing a standard (can think of it as an evolution of
the IDC protocol)
• GLIF is pushing the envelope, promoting functionality and
interoperability on a global scale and move to a standard
• OpenFlow is pushing the envelope under the hood, within and outside
of GENI
– Initially connect OpenFlow “islands” by Layer 2 VLANs using IDC
protocol
– Eventually, we’ll figure out what “OpenFlow peering” means

IRNC SP:IRIS
• NSF Grant # 0962704
• IRIS will provide a software framework to simplify the task
of end-to-end network performance monitoring and
diagnostics
– Based on the widely deployed perfSONAR-PS infrastructure
and protocols
– Facilitates broader deployment of perfSONAR enabled
resources; increasing the likelihood of diagnostic resources
being available along the end-to-end paths
• Integrates with existing deployments on R&E networks
(ESnet, GÉANT, Internet2, Regional and NRENs) as well as
those maintained by scientific VOs (USATLAS, LHCOPN,
eVLBI, REDDnet)
• Will work with IRNC ProNet awardees to customize
deployment for target network functionality
• Target end date is April 2013
11 – 4/11/2016, © 2011 Internet2
IRNC SP:IRIS Development Status
• perfSONAR-PS v3.2.1 release imminent
– New features supporting IRNC Pronet awardees
• Nagios Plug-ins
• Improved IPv6 support
• Improved bandwidth/latency analysis
• Continue to meet with all awardees to advise on hardware
choices and best practices for tool deployments
12 – 4/11/2016, © 2009 Internet2
IRNC SP:DyGIR
• NSF Grant # 0962705
• DyGIR will provide a component based solution for
scheduling dynamic circuits on IRNC ProNet infrastructure
– Utilizes the OSCARS software suite, developed by ESnet
– Integrates circuit statistics and networking monitoring via
the perfSONAR-PS framework
• Capabilities will integrate with existing backbone networks
(ESnet SDN, GÉANT AutoBAHN, Internet2 ION), as well as
emerging campus deployments (DYNES – an NSF MRI
Funded effort).
• Will work with IRNC ProNet awardees to customize
deployment for target network functionality
• Target end date is April 2013

– OSCARS port will (?) be needed, work should be complete 1st
quarter 2012

IRNC Outreach to ProNET Awardees
• ACE
– perfSONAR-PS test points to be available, along with periodic
monitoring to select locations within GEANT
– Planned IDC at MANLAN 1st Quarter of 2012
• AmLight
– IDC available in the AMPATH exchange for use on International
Links
– IDC Peering with RNP established
– perfSONAR-PS monitoring available
• GLORIAD
– Discussed current DYGIR and IRIS activities
– Currently have ability to create VLANs on infrastructure. Looking
to integrate with dynamic circuit networks over next couple of
years.
– Exploring current GLORIAD peerings and heavy users to determine
what use cases could benefit from dynamic circuits.
– Exploring best way to capitalize on perfSONAR – specifically
looking at ways to publish passive flow data currently collected by
GLORIAD using perfsONAR protocols

IRNC Outreach to ProNET Awardees
• TransLight/Pacific Wave
– Established working group to install perfSONAR-PS
monitoring software at endpoints and participants
in the region
– Have put out a questionnaire to participants and
end sites to determine perfSONAR availability.
Some deployments already happening
– Evaluating dynamic capabilities
• TransPAC3
– Have traded topology information and are determining
what switches in the infrastructure to put under
dynamic control. Will likely peer with ION and JGN2.
– Currently has perfSONAR-PS test points, and periodic
tests with APAN

DYNES Motivation
• Data movement to support science:
– Increasing in size (100s of TBs in the LHC World,
approaching PB sizes)
– Becoming more frequent (multiple times per day)
– Reaching more consumers (VO sizes stand to
increase, more VOs)
– Time sensitivity (data may grow “stale” if not
processed immediately)
• Traditional networking:
– R&E or Commodity “IP” connectivity is subject to
congestion by other users
– Supporting large sporadic flows is challenging for
the engineers, and frustrating for the scientists
17 – 4/11/2016, © 2011 Internet2
DYNES Motivation
• Solution
– Dedicated bandwidth (over the entire end to end path)
to move scientific data
– Invoke this “on demand” instead of relying on
permanent capacity (cost, complexity)
– Exists in harmony with traditional IP networking
– Connect to facilities that scientists need to access
– Integration with data movement applications
• Invoke the connectivity when the need it, based on network
conditions
• Proposed Deployment:
– Software and hardware support spanning domain
boundaries
• Campus
• Regional
• Backbone
– Integration with existing technologies and
deployments
