1. Circuit Services - IPTV Christian Todorov Internet2 Fall Member Meeting October 9, 2007

2. Christian Todorov2 Internet2, Circuits & You Where we have been Changing needs Why circuits are different How Internet2 provides circuits Internet2 Circuit offerings Who to contact

3. Christian Todorov 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… 3

4. Christian Todorov 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 4

5. Christian Todorov 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 5

6. Christian Todorov 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 6

7. Christian Todorov 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 7

8. Christian Todorov 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 50Mbps to 10Gbps Have no fee for use Short duration ~2 weeks Best effort service 8

9. Christian Todorov 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 9

12. Christian Todorov12 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 Internet2 Network Node Architecture

13. Christian Todorov 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 1-1-08 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 13

Christian Todorov Multi-Service/Domain/Layer/ Vendor Provisioning Regional Network Internet2 Network ESNet Dynamic Ethernet TDM GEANT IP Network (MPLS, L2VPN) Ethernet Router SONET Switch Ctrl Element Domain Controller LSP Data Plane Control Plane Adjacency Multi-Domain Provisioning Interdomain ENNI (Web Service and OIF/GMPLS) Multi-domain, multi-stage path computation process AAA Scheduling TDM Slide from Tom Lehman, ISI-East GUI XML AST

15. Christian Todorov 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 Available now Circuit fees available on request 15

16. Christian Todorov Who to Contact DCN connection requests or information: Network@internet2.edu Rick Summerhill is lead Static circuit requests, fees and information: waveco@internet2.edu Christian Todorov is lead Member and Partner Relations assistance: univengage@internet2.edu Marianne Smith is lead 16
