Architecture
Dynamic Circuits infrastructure uses circuits provided by the core infrastructure interconnected with “Multiservice Switching boxes” located at PoPs
Each box has a static circuit to each topologically adjacent box
The Multiservice Switching infrastructure uses circuits from core infrastructure
Circuits between boxes carry multiplexed streams which carry user circuits
Each stream consisits of multiple STS-1s (50 Mbps)
Number of streams limited by total bw of circuit between boxes

9. Using Dynamic Circuits
Internet2 Dynamic Services
Using Dynamic Circuits
Typically Internet2 provides a segment of a point to point circuit between users
Dynamic Circuit Infrastructure connects to other Domains
Regional Networks
Other National and International Networks
Creating circuits dynamically assumes an infrastructure of nodes and links in place over which the dynamic circuit is to be established
Initiating a dynamic circuit is done by making a request to a dynamic circuit controller
Controller may be a person or software- more on this later

11. Data Plane and Control Plane
Internet2 Dynamic Services
Data Plane and Control Plane
Data Plane provides the circuit segments that are joined to make an ETE circuit
Control Plane creates ETE circuits by
selecting a path of circuit segments
Controlling switching of segments to create the path
Tear down ETE circuits and return segments
Both are part of dynamic circuit service

13. Internet2 Dynamic Services
Control Plane
Initiating a dynamic circuit is done by making a request to the control plane
Each domain has its own control plane
Control plane may be
NOC taking requests and configuring devices
Control plane software that configures devices
Setting up circuits across domains requires coordination of control planes of each domain
Control plane software for single domains is commercially available
Control plane software that coordinates between domains is a being studied and worked on in standards bodies
HOPI has working code that has a pilot version of cross domain control coordination

14. Connecting to other International and National Networks
Internet2 Dynamic Services
Connecting to other International and National Networks
The expectation is that there will be an international infrastructure of dynamic circuit providers
Some will interconnect directly to each other
Some will interconnect at well defined exchange points
GLIF uses term GOLE
Global Optical Lambda Exchange

15. International Service Trials

16. Initial Connections to Dynamic Circuit
Internet2 Dynamic Services
Initial Connections to Dynamic Circuit
Initial connection to Internet2 may be by a static VLAN from user
Switching will be done by Internet2
Control of VLAN creation can be added later
Experimentation with software control of VLANs can be done with HOPI
Content Slide

17. Connecting between networks
Issues
Stitching Ethernets and SONET
Finding Paths across multiple domains
Controlling circuits across domains
Monitoring and debugging
Collaborations
ESNet and GEANT
making cross domain circuits
Establishing initial naming conventions
Establishing “stitching” rules
Many others in various arenas, including Amsterdam, NICT, CANARIE
Work in IETF, OGF

18. HOPI Role Hybrid Optical and Packet Infrastructure
HOPI is a testbed for developing and deploying dynamic circuit services and applications
HOPI has experimental control plane software which may be used by other domains
HOPI can be used to test new applications prior to roll out on persistent dynamic network
HOPI is not for applications that cannot permit having
