3. Natively supported IPv4/v6 and multicast
Abilene Network
Internet2’s previous network (Abilene) was IP only and based on unprotected 10G (OC-192) waves on the Qwest infrastructure
Utilized IS-IS
Natively supported IPv4/v6 and multicast
IP is great… for most people… most of the time…

4. Dedicated infrastructure was becoming a requirement
Changing Needs
As the capabilities available to the research community changed, the demands on the network also changed
e-science applications and facilities grew and exerted greater performance pressures on the network where TCP and shared environments were no longer acceptable
Dedicated infrastructure was becoming a requirement

5. Demands on the Network Entering the age of large scientific facilities
Large Hadron Collider at CERN
Very Long Baseline Arrays (radio astronomy)
Large Synoptic Survey Telescope ( ) – 30TB/night
An increasingly diverse set of demanding applications are utilizing network resources
Telemedicine: BIRN project, proteomics, tele-surgery, remote ICU, radiology: high-resolution 3D color fMRI brain scan = 4.5PB
Telepresence: master classes, virtual classrooms, tele-psychiatry
High performance video delivery: Uncompressed HD, Cinegrid
Disaster Recovery and distributed storage

6. Enable the user – the network as a service
The New Requirements
High performance applications are dependent on high performance networks
Networks must be fast, reliable, scalable, have flexible architectures, be cost effective, capable of delivering multiple services across multiple network layers, easy to operate and maintain, and have a view towards the future
Enable the user – the network as a service

7. The Internet2 Network Overview
Layer 1: Managed wavelengths from Level(3) Communications
Level(3) owns and manages Infinera optical gear: responsible for software upgrades, equipment maintenance, remote hands, sparing, NOC services
Internet2 NOC has total provisioning control
Layer 2: Internet2 owned and managed Ciena CoreDirectors
Using DRAGON GMPLS control plane
Layer 3: Internet2 owned and managed Juniper T640s
Expanded Observatory
Platform for layer 1/3 network performance data collection, collocation, experimentation
perfSONAR integration for intra- & inter-network performance analysis
International connectivity
Layer 1 network extended to international exchange points in Seattle, Chicago and New York City
Peering points in Seattle, PAIX, Equinix Chicago

9. Circuits: Why They are Different
IP networks switch packets of information across shared networks to multiple locations and operate at Layer 3
Shared packet networks are well suited to applications where data transfers are intermittent, multi-point, or have smaller file size transfer requirements
A “best-effort” service
Represents the largest number of uses of the current network
Circuits connect two discreet endpoints with dedicated connections and operate at Layer 2 or below
Circuit based networks are well suited to long duration, point to point connections that support large data transfers or transfers that require very predictable network performance
Is a dedicate resource
Connection oriented service
Represents a small number users who have high demands of the network: bandwidth, performance, desire to run alternative protocols

10. Wavelength & Circuit Services
Connection oriented services provide for:
Guaranteed bandwidth and predictable jitter and latency (repeatable, dependable performance between collaborating sites)
Traffic segregation (support specific policy or traffic engineering requirements)
Router bypass: Express links created for high-bandwidth, limited duration long-haul traffic reducing the need for mid-path L3 interfaces
Cost efficiency: L3 router blades cost > L2 ports > L1 or L0 interfaces
Capability tradeoff but could possibly improve performance

11. Internet2 Circuit Services
Internet2 offers two types of Circuits
Static circuits
Exist on the Circuit Infrastructure supported by both the Infinera and Ciena devices
Manually provisioned by the NOC
50Mbps to 10Gbps
Fee for service
Longer duration: months to years
Can have dedicated protection
A contracted, assured service
Dynamic Circuits
Exist within the Dynamic Circuit Network (DCN) supported by the Ciena CoreDirectors
Provisioned automatically
Requires participation in the DCN protocols
Have no fee for use
Short duration ~2 weeks
Best effort service

12. Connecting to the Internet2 Circuit Infrastructure
Accessing the Circuit Infrastructure
One must have a connection to the Internet2 circuit infrastructure in order to access the Internet2 circuit services.
The circuit connection is separate from the IP connection
The standard connection to the circuit infrastructure is either 1GE or 10GE – other interface types are supported at an additional fee
ONE physical connection to the circuit infrastructure on the Ciena CoreDirectors will support BOTH the static circuit service AND the Dynamic Circuit Network
For the first year, the connection to the Cienas are available to IP connectors at no additional fee for a standard connection (1GE or 10GE) that is equal in bandwidth to the contracted IP connection, e.g. 10G IP connectors receive the use of a 10G circuit connection. (Non-connectors may be subject to additional port fees)
Circuit connections are available to Connectors, members and peers

13. Internet2 Network Node Architecture
Example of Optical only Node for connected RON or Peer Network

14. Internet2 Network Node Architecture
Infinera DWDM Gear - Static at the start
Grooming capabilities in ADM to provide sub channels and HOPI types of activities at the start
Simplified and standardized interface to connectors, exchange points, and other global research and education networks - 2 x 10 Gbps interfaces
Measurement and control servers will support the node

15. Dynamic Circuit Network
The Dynamic Circuit Network (DCN) is considered a network due to its characteristics and behavior: it is protocol driven, has the capability to determine paths, can exchange network information with neighbors and it is aware of its own resources
The DCN concept expands the notion of networking where a network facility is able to provide the most appropriate resource for a given demand
Dynamic Circuit Network (DCN) is developmental until and persistent thereafter
Invitations are currently being sent out by Internet2 to the connectors for participation in DCN
A DCN connection does not imply a connection to the IP network
DCN participation is critical to its success as its value grows with the number of participants

16. Static Circuits
Static circuits are manually provisioned by the NOC and are intended for longer durations: the typical concept of a circuit
A contracted, fee for service offering based on bandwidth, duration and distance
Can exist both on and off of the Internet2 network footprint
Intended to provide dependable, dedicated and deterministic service to connectors
A static circuit does not imply a connection to the DCN or the IP network
Includes full 10G waves
