  1. Connecting to the new Internet2 NetworkWhat to Expect… Steve Cotter Rick Summerhill FMM 2006 / Chicago

  2. Outline • Network Infrastructures • Services on The Infrastructures • Description of Circuit Services • Control Plane

  3. The Network

  4. Optical Topology

  5. The Network • Made up of four architecturally distinct infrastructures: • the core infrastructure • the IP infrastructure • the Multiservice Switching infrastructure • the HOPI Testbed infrastructure • Initially, circuit services across different architectures will be kept separate to maintain integrity • As network matures, level of integration of infrastructures will increase

  6. Services

  7. IP Services • Continuation of IP services offered on Abilene plus commercial peering and commodity transit • 9 router locations: NYC, DC, Chicago, Atlanta, Houston, KC, LA, Salt Lake City, Seattle

  8. IP Services • Connector builds out to PoP and I2 will carry connection to the nearest backbone router • 10Gbps connection over core infrastructure • <10Gbps may go over multiservice switching infrastructure • Additional “opt-in” services will require separate BGP peerings, I2 suggests connect with: • VLANs enabled (Ethernet connections) • Frame Relay DLCIs set up for SONET connections

  9. Commercial Peering Service • As configured for beta trial, we anticipate using separate peerings between I2 and participating connectors • Use VLANs or Frame Relay DLCI • Connect at 10Gbps to commercial exchange points in Chicago, Palo Alto (PAIX), and possibly Ashburn • Ongoing trial - NTAC and I2 staff are seeking community input on how to best offer this service

  10. Commodity Transit Service • Offer optional Level3 commodity through IP connection at reduced rates • Level3 will also allow direct 1GE connections to Level3 commodity network • Will add other transit providers in the near future • Separate BGP peering requiring VLANs or DLCIs • NTAC Working Group providing input

  11. MPLS Services • Internet2 network staff and the IU NOC will work with connectors to implement MPLS tunnels through the Internet2 Network on a case-by-case basis

  12. HOPI Test Service • Purpose is to allow experimentation in implementing and using dynamic circuits • Experimental in a number of ways: • Footprint limited Internet2 Network footprint • Uses experimental control plane software to create circuits and to interconnect with other domains using their control software • Allows other networks to interconnect with it to test their interdomain circuit capabilities

  13. HOPI Test Services • Connect at I2 PoP with HOPI access point • Physical connection can have one or more sub-circuits over 1G or 10G interface • Kinds of connections expected to change over time as other devices added • Initially, use existing HOPI Force 10 Ethernet switches

  14. HOPI Test Services • Connections across HOPI are p-2-p Ethernet VLAN based circuits in increments of 100 Mbps • User input devices must support 802.1q VLAN capabilities • Requests for bandwidth can me made using: • GMPLS-style Peer Mode, GMPLS-style UNI Mode, Web Service API or email/phone

  15. HOPI Test Services • HOPI may be used to: • Test dynamic services developed by other domains • Likely interconnect HOPI to test labs and with other organizations (regionals) • Test applications prior to using them on dynamic or static circuit services (i.e. performance measuring software for dynamic networks) • For more information, contact Rick Summerhillrrsum@internet2.edu

  16. Circuit Service • Major aspects of the circuit service: • Physical connection between Internet2 and user device (type and speed) • Circuit bandwidth (multiples of STS-1s) Note: Speed of interfaces do not have to match

  17. Static Circuit Service Overview • Longer lasting point-2-point circuits across network by connecting to Infinera or Ciena gear • Infinera via 10GE or OC-192 interfaces • Across network can be either Ethernet or SONET framed • Ciena via 1GE, 10GE or SONET OC-48, OC-192 interfaces • Ethernet frames encapsulated in SONET using GFP • SONET can be channelized or not (OC-48 or OC-48c) • Across Network is always SONET in multiples of OC-1 • Provisioned by Internet2 NOC in coordination with user’s NOC.

  18. Multiservice Switch Description • Each Ciena Multiservice Switch has two or more trunk side SONET circuits connecting it to other switches • Client side can be Ethernet or SONET - 1GE, 10GE or OC-48, OC-192 interfaces • Ethernet frames encapsulated in SONET using GFP • SONET can be channelized or not (OC-48 or OC-48c)

  19. Dynamic Circuit Service Overview • Shorter period (minutes to months ) point-2-point circuits across Network • Connected to Ciena Multiservice Switching infrastructure • Connect as single circuit to be switched or multiple circuits multiplexed over the physical connection • Will use a set of waves on the core infrastructure dedicated to the dynamic wave service

  20. Dynamic Circuit Ethernet Requirements • All Ethernet connectors must be capable of supporting 9K (MTU) payload frames. • Ethernet participants may be tagged with VLANs or untagged, and VLANs may be switched internally on the transport. • That is, a VLAN tag on one end need not be the same as a VLAN tag on the far end. • Physical connections that use Ethernet must support 802.3x (flow control). • Physical connections using Ethernet VLANs must support 802.1q (VLAN).

  21. Dynamic Circuit Details - Ethernet • Provided as a p-2-p Ethernet circuit • Frames are encapsulated into SONET streams using Generic Framing Protocol (GFP). • Encapsulation and decapsulation done at ingress/egress • Streams divided into one or more OC-1 channels using Virtual Concatenation (VCAT) • It is strongly recommended that all Ethernet connectors support IEEE 802.1p (flow control) • Circuits between networks passed as GFP encapsulated SONET

  22. Dynamic Circuit SONET Requirements • All SONET connectors must support VCAT and LCAS • All SONET connectors providing Ethernet services must support GFP

  23. Dynamic Circuit Details - SONET • Provided in multiples of OC-1s • Incoming SONET can be channelized or not (i.e. OC-48 or OC-48c) • Connections across the Ciena MS infrastructure are always SONET

  24. Multiservice Switching Infrastructure Control Plane

  25. Multiservice Switch Control Plane Overview • Control plane software will: • Manage the set up of dynamic circuits • Keep track of bandwidth • Allow reservation of future bandwidth • Authenticate users requesting bandwidth • Report on network status • Additional software integrated with Ciena software to provide additional capabilities

  26. Dynamic Circuit Control Plane • Automated services are expected in the near future • Will use DRAGON-style control plane capabilities • Control plane channels will be transported via IP, and connectors will be offered several options for implementation and/or interaction with the dynamic control plane • Initial deployments of control plane software will take place on HOPI test service before moving to the production network

  27. Dynamic Circuit Service Provisioning

  28. Dynamic Circuit Service Provisioning • Uses control plane software to set up circuits • Initially only I2/NOC staff after requested by user • Eventually software added to allow circuits to be created by user request • For cross-domain circuits, think of I2 Network circuits as segments of longer p-2-p circuits • Cross-domain coordination via email/phone or software to do automatically • Contact the NOC for circuit setup, NOC engineer will be assigned to coordinate with other networks to create the required paths across the network.

  29. Dynamic Circuit Service Provisioning • Cross-domain connections require appropriate control plane software • Internet2 will provide experimental software to regionals

  30. Connecting Dynamic Circuits to Users • Scenario #1: Two regionals and their users • Physical connections to regionals made – we expect this will typically be an Ethernet connection that supports VLANS • Each regional creates VLAN circuit to its user and makes connection to Internet2, then segments joined to create end-2-end circuit

  31. Connecting Dynamic Circuits to Users • Typically regional provides its own circuit multiplexing for its user and provides circuit to I2 • Multiplexed connection sent across I2 network and delivered to end regional • Circuits set up and managed by control plane software • May be done automatically across regional domains if using compatible control plane software

  32. Connecting Dynamic Circuits to Users

  33. Connecting Dynamic Circuits to Other Networks • Scenario #2: Connecting to similar services provided by other national or international networks • By either direct connections or at exchange points • Control plane interface is similar to the I2/RON model • I2 working on user authorization and network information sharing with other networks

  34. Connecting Dynamic Circuits to Other Networks • Using these interconnections and appropriate manual and automatic control of circuit switching, Internet2 will be able to be a partner in creating circuits from users in the United States to users connected to other international core networks • Today, working to define service definitions and info sharing policies to enable this

  35. Applications • TeraGrid • High definition videoconferencing • eVLBI Radio telescopes • Remote medicine • IP load shifting • File transfer – Phoebus / VFER

  36. Control Plane Rollout

  37. Control Plane Rollout – Current Plan • Initially, Ciena control plane will be used to create circuits by NOC from user requests • Feb 2007 – web form available to request connection, initially filled by NOC • Web form to interface with control plane software to make connections without NOC intervention • Feb/Mar 2007 – software made available to regionals for them to provide switched circuits to users

  38. An Example of How to Connect to HOPI and the Internet2 Network - Phase 1 • Campus connects through RON using static VLANs and deploys VLSR on PC connected to switch (GMPLS control plane) • Ethernet based • Connect to HOPI control plane

  39. Phase 2 • Add NARB (could be same PC) • Separates the campus domain from HOPI domain • Now have separate control planes

  40. Phase 3 • When ready, RON implements GMPLS control plane
