  1. FloridaMIX Next Generation Exchange February 2001

  2. Agenda Introduction/Background Operations “Classic” Options • Optical/TDM Transport Core • ATM Transport Evolution Facilities/Survivability Participants

  3. Design Team • BellSouth.net Susan Campbell Mike Duckett, Sr. Director, Eng. & Architecture Robbie Harrell Christian Kuhtz Troy Meuninck Deron Ringen Tim Seaver (+ various clueful vendor people & peering geeks)

  4. Company Background • $27.6 Billion Total Revenue; $3.54 Billion Data Services Revenues (2000) • 956,000 Internet Customers • 3.4 Million Fiber Route Miles Deployed • Customers: • 34.7 Million US • 6.9 Million Latin America

  5. What is it? • FloridaMIX is an exchange facility providing infrastructure in the greater Miami area to connect organizations with each other, regardless of their geography. • Minimum DS-3 port speed, up to OC-48 (at launch; OC-192 mid 2001). • Ethernet (100base, GE) introduced 3Q 2001. • SONET & SDH, conversion late 2001. • built from the ground up to be resilient, highly available, reliable, diverse, .. • Hosted by BellSouth.

  6. Why? • Infrastructure to support multimedia content distribution will be critical to economic development of the tri-county area, Florida and the Southeast • Improved access to International Markets • Enable economic private peering infrastructure for large ISPs • Provide smaller ISPs and private businesses local access to the Internet backbones

  7. Design Criteria • Guaranteed Peering Quality • Flexible, rapidly provisionable, any to any connectivity. • Independence • Location • Carrier • High degree of survivability

  8. R&D facilities • BellSouth.net IP Engineering & Architecture Lab @ Perimeter (Atlanta, GA) • Dedicated, substantial replica of components (optical transport core, TDM/IP/MPLS fabrics, provisioning engines) for the FloridaMIX. To be used for Design, Testing, Regression Testing, Troubleshooting, Design Evolution. • Immediate access to 40+ IP networking & systems engineering people. • Additional testing efforts at various vendor labs around the nation.

  9. Connection Models • Two general models are available: • Colocate at FloridaMIX Data Center • Attach remotely to one or more FlordiaMIX POPs.

  10. Core Layout Co-location Data Center POP POP POP POP OC-48 DWDM fabric

  11. Coverage Boca Raton Fort Lauderdale Downtown Miami West Dade

  12. Example Applications • Traditional Public & Private Peering • Content Distribution Injection Point • Backup Data Centers for South America. • Generic Broadband, Rapid Provisioning Infrastructure (Bandwidth on Demand) • Bandwidth Brokerage • …

  13. Operations • BellSouth will operate and manage the FlordiaMIX backbone and equipment through dedicated organization. FloridaMIX NOC run by optical & IP engineers. • 3 engineering seats (24x7) in Atlanta • 3 engineering seats (24x7) in Miami • Merit will manage the public peering RS (MOU in progress). • Communication is a top priority.

  14. Pipes • Core and access fiber infrastructure for FlordiaMIX provided by • FPL Fibernet • BellSouth Telecommunications • Any optical loop will accepted, as long as conduit space is available. Electrical interfaces on a case-by-case basis. • Intent is to be connected to every cable landing site. Negotiations in progress.

  15. Access • Conduit access must be negotiated with landlord (not affiliated with BellSouth). As long as landlord provides conduit space, we will connect. • Contractual guarantees for “any loop” will be available – intent: “no carrier jail”.

  16. Transport Highlights • Robust optical transport service offerings ranging from an unprotected service to full route redundancy with SONET/SDH like recovery and restoration (< 50ms per link including detection and restoration) • Service connections support SONET and SDH framing • Service connection capacities range from STS-1 to STS-48 in STS-1 increments • Support for optical VPNs

  17. Fiber Layout POP POP POP POP FPL FiberNet 1 dark fiber pair each BST

  18. Fiber Layout • 6 λ per inter-POP pair @ turn-up • installed capacity for 24 λ per POP (equipment capable of 80 λ) • no concern about fiber grade w/ OC-48, OC-192’s depend on actual fiber condition. • Can mix and match OC-48 & OC-192 (no interruption once OC-192 is ready).

  19. Optical POP layout SycamoreSN8000 SycamoreSN16000 Edge Core SycamoreSN8000 DWDM

  20. Equipment Choices • Why Sycamore? “If you believe software is the critical gate, you have to go with a software centric solution. Neccessary for on-demand enhancements, and SONET/SDH is crucial in an international environment.”

  21. TDM Transport

  22. ATM Transport

  23. ATM Transport • The ATM transport provides a fully redundant OC12 backbone. • Public peering over ATM at DS3,OC3 and OC12 port speeds utilizing ATM UBR class of service. • Private peering and transport over ATM at DS3, OC3 and OC12 port speeds utilizing ATM CBR, VBR and UBR class of service.

  24. ATM Transport • Minimum guaranteed bandwidth over the public ATM infrastructure. • Rapid provisioning to meet increasing customer requirements. • No overbooking or over-subscription allowed in order to maximize throughput of IP based traffic. • CMN capabilities are in the works.

  25. Any-to-Any connectivity Closed User Group Guaranteed Bandwidth Multiple Transmission Interfaces Types Intelligent Congestion Management Transparent transport of tagged frames Link Aggregation Jumbo Frame Support Loop Detection Multicast Traffic Manageability of Service SLA Support Unified Control Plane Architectural Requirements

  26. Phase II

  27. Phase II

  28. Facilities • 4 POPs • 10,000 sq.ft each • Colo Data Center in West Miami • 70,000 sq.ft. raised floor, 100,000 sq.ft. total • Additionally Hosting Centers are obvious alternates (3rd party)

  29. Survivability • no site is in category 1 evac zone (subject to storm surge) • 3 POPs category 5, 1 POP category 3 • Own generator, battery plant per site. 6 hrs minimum battery coverage. (Colo has UPS) • “Miami has at times severe weather conditions, you have to have the resources and committment to fly in resouces (people, equipment, fuel) to guarantee high availability and resiliency.”

  30. Build-Out Plan Three Phases: Phase 1: Phase 2: Phase 3: Private Peering via Optical, TDM, ATM Public Peering via ATM Private & Public Peering via Ethernet. Private & Public Peering via MPLS. Fully Automated Provisioning

  31. Current Timeline 1st Quarter 2001 • Deploy phase one (Target: very late CQ1) • Optical Transport • ATM private and public services 2nd Quarter 2001 • Assess and define Ethernet and transport agnostic transport mechanisms.(MPLS, GMPLS, MPLS “Circuit Cross Connect” , RFC2547(bis) layer 3 VPN’s, etc)

  32. Participants • The following have signed LOI’s w/ publicity release statements: Qwest, Diveo, Intermedia, FPL Fibernet, UUNET (a WorldCom Company), Exodus, PSINet, Nova Southeastern University, Computer Office Solutions, Hyperbyte, Cyberlinyx, Advanced Data Center, Inc., Worldwide Internet Services, Synergyx, Worldwide Telnet and Florida Atlantic University

  33. Thank You! <FloridaMIX@arch.bellsouth.net>

  34. ATM Transport • DS3-OC12 support • Scalable non-blocking switch fabric • Support for automatic protection switching (APS) for redundancy and protection • Support of both SONET and SDH framing • Intelligent cell discard (visibility into IP frames) • Per VC queuing • Congestion control • Flow control • Ease of provisioning

  35. ATM NAP Transport Pipe ATM UBR VC OC-3 Pipe DS-3 Pipe Peer1 ATM IX Peer3 Peer2 DS-3 Pipe

  36. ATM NAP 25 Mbps offered bandwidth Congestion Point Peer1 ATM IX Peer3 Peer2 25 Mbps offered bandwidth

  37. ATM NAP Cell Cell Cell Cell IP Chunk IP Chunk IP Chunk IP Chunk … packet shredding occurs @ Peer1 & Peer2 IP Packet

  38. ATM NAP Cell Cell Cell Cell IP Chunk IP Chunk IP Chunk IP Chunk … congestion cell discard occurs @ ATM IX switch IP Packet

  39. ATM NAP Cell Cell Cell IP Chunk IP Chunk IP Chunk … re-assembly fails @ Peer3 IP Packet

  40. ATM NAP • Conclusion (in a nutshell): • Must have packet aware discard mechanism to guarantee decent goodput. (otherwise, for example, <5% cell loss can translate into 70+% AAL5’ed IP frame loss/corrupted frames). • Testing shows ABR w/ VSVD in the core allows for very nice IP traffic guarantees over ATM. • Long term migrate to a packet based infrastructure. => Strong focus on using Ethernet & MPLS w/ strong R&D effort.

  41. Congestion Management • Frame based congestion management • Primarily at the provider edge of the FlordiaMIX. • Pushed out to “customer” edge in the case of hosting centers/carrier hotels for multiple providers sharing a transport pipe. • Exact configurations are presently under study

  42. Ethernet CUG • Ethernet switches at the FloridaMIX can join 802.1q VLANs to create closed user groups (CUG) for peering purposes. • Multicast • experimental peering services such as IPv6
