Internet2 “DCS” Network and HOPI

10 Gigabit Ethernet

1 Gigabit Ethernet or SONET/SDH

OC192 SONET/SDH

I2 DCS: Ciena CoreDirector10 Gigabit Ethernet

1 Gigabit Ethernet

I2 HOPI: Force10 E600

10 Gigabit Ethernet

What is an Internet2 “dynamic circuit”?

• User initiated (via software) setup of:• Point to Point Ethernet VLAN (HOPI)• Point to Point Ethernet (VLAN) Framed

SONET Circuit (DCS)• Point to Point SONET Circuit (DCS)

• Bandwidth provisioning available in 50 Mbps increments on DCS network

Why dynamic circuits?

• Benefits:• Guaranteed Bandwidth• Fast setup time• Resource reservation and allocation done

automatically• Traffic Engineering• Monetary cost of equipment (Layer 2 vs

Layer 3 interfaces)

Who do dynamic circuits help?• High bandwidth transfers that need a

guaranteed bandwidth rate• Terapaths

• Low latency requirements• Video Conferencing• Virtual Worlds

• “Intelligent” networking• Network links no longer static • Network can change with load requirements

How do you use Internet2 dynamic circuit services?

• Physical Connection• 1 or 10 Gigabit Ethernet Connection (DCS

and HOPI)• OC192 SONET (DCS only)

• Software• DRAGON• OSCARS (mid-term)

DRAGON• NSF Funded project run by MAX and ISI East• Jerry Sobieski (MAX)• Tom Lehman (ISI East)

• Allows for intradomain and interdomain circuit path calculation and setup

• Currently deployed on HOPI• Deployed by the end of summer 2007 on

DCS

DRAGON – Key Components

• Virtual Label Switched Router(VLSR)• Single PC connects to supported switch• Accepts RSVP packets and configures switch

• Network Aware Resource Broker (NARB)• Performs inter/intradomain path calculation• Exchanges interdomain topology• Limited resource scheduling

DRAGON – Key Components

DRAGON User Software

• User passes circuit parameters• Source, destination, bandwidth• Many optional fields such as VLAN tag

• DRAGON Interfaces• CLI• ASTB (XML)• Web Page• Coming soon..OSCARS web service interface!

DRAGON User Software – CLI

• Command Line Interface (CLI) available

• Peer-to-Peer Mode• Log-in to ingress VLSR and configure

• User Network Interface(UNI) mode• Command line run on client• RSVP sent from client to ingress VLSR• RSVP message terminates at destination

host

DRAGON User Software - ASTB

• Application Specific Topology Broker (ASTB) provides XML interface to DRAGON

• Commit multiple LSPs at once to create AST

DRAGON User Software – Web Interface

• GUI frontend to the ASTB

• Allows “point and click” creation of circuits

• Google Maps API

OSCARS Integration

• Integrating OSCARS code with DRAGON to allow for interoperability with ESNet

• Book-ahead reservations

• Web Service Interface

• AAA using X.509 certificates

• Development release with limited topology exchange by end of summer, deployment mid-Fall 2007

What do I need to get started?

• Option 1: Install DRAGON (and OSCARS)• Assemble group of compatible switches or write

drivers for your switches• Install VLSRs for each switch and a single

NARB for your domain• Peer with Internet2 or RON software instance

so can build interdomain circuits

• Option 2: Build own application that interfaces to RON or Internet2 instance

Conclusion

• Internet2’s HOPI testbed and DCS network will provide dynamic circuits

• Dynamic circuits provide exciting opportunities for researchers

• Software developed and in development

• Many at Internet2 willing to help you to deploy software
