InterDomain Dynamic Circuit Network Demo
Joint Techs - Hawaii Jan 2008

Interdomain
Dynamic Circuit Network
Global network that allows dynamic ckts to be created across multiple circuit networks
Internet2, ESnet and Dante have worked in the DICE control plane working group
Developed and continue to develop IDC protocol
 Interdomain dynamic circuit infrastructure is in place and being enhanced
Additional Collaboration with Nortel and University of Amsterdam

Agenda
SC07 presentation overview
Infrastructure at time of SC07
Weather Map of DCN today
Quick overview of applications on weathermap
GOLEs in DCN
 IDC architecture
Connecting a Campus User
DCN software suite
DCN status

Global DCN Infrastructure
at SC07 timeframe
Physical Infrastructure
at SC time
Current Infrastructure of DCN
LHC applications on DCN
Phoebus and DCN
Phoebus breaks tcp connections into pieces to improve performance http://e2epi.internet2.edu/phoebus.html
Phoebus has the ability to create and use DCN a piece of the connection
Phoebus gateways are in place in Salt Lake and Syracuse NY now, being used
Other Phoebus gateway have been used in Ireland, Greece, and Poland, and more are being deployed in US now.

DCN GOLEs
Exchange Points for Dynamic Circuits
GOLE policy issues
Individual DCN GOLE is policy free
GOLE is non blocking
If both links agree path between them is made
This is initial demo being done at here and at JT
When GOLEs connect to each other
Link between GOLEs is limited resource
Now have to have policy that determines what is allowed on inter GOLE link
GOLE role :) may be
ÒsuperdomainÓ aggregating info on other domains
Part of GOLE domain that consists of only GOLES, administered by some standards body
GLIF role in defining DCN GOLE?

IDC role in DCN
IDC is what allows DCNs in different domains communicate
IDC communicates with user and with other domains
IDC requests services from its Domain Controller
Different implementations from
Internet2, Esnet, GEANT, Nortel

IDC Architecture
RONs and Campuses connecting to DCN
DCN Software Suite
Suite combines DC and IDC software
DC - DRAGON
IDC - OSCARS
Suite is a Òmatched pairÓ of software
Version 0.1 released Jan 2, 2008
Version 0.2 Jan 18,  2008
Small changes and documentation update
Version 0.3 planned for April 2008
Software suite matches what is running in Internet2 DCN and ESNet SDN

Monitoring Dynamic Circuits
Monitor plane - both sides can monitor and deploy
Monitor links for infrastructure status and activity
Monitor ETE circuits for user status, traffic  and debugging
Ongoing development and standards activity in this area
perfSONAR is our choice of tool - will be enhanced to add additional support
Dynamic circuits make naming and syntax standards imperative
Work with operations to define what is needed - especially between domains

Operational State of DCN
Internet2 and ESNet are dynamic circuits are in ÒdevelopmentalÓ state
Good availability, ready to work with applications developing capabilities on network
Want to tune functions and policy to meet needs of real users
Support mainly from developers, starting to work with operations staff to transfer operational tasks to them - probably 6-12 months away
Support not 24/7, expect to respond to problems in 24 hours during work week.  Often better.
Monitoring and debugging in development
Other DCN networks are in earlier stages
