  1. State of the Network: PennREN

  2. Agenda • What does PennREN look like today? • Network and Operational Overview • Current & Future Technical Projects • Why should you care? • This is YOUR network

  3. 1800+ Miles of Fiber http://www.Kinber.org/kmz

  4. Fiber Plant • 15 Segments across the Commonwealth • 72 locations have fiber terminated for PennREN Point of Presence (POP) • 13 Service Nodes have diverse fiber entrance paths • OFS TrueWave Reach Fiber on the pole • OFS AllWave Flex Fiber for building entrances

  5. Segment C

  6. Fiber Termination Scheme

  7. Segment C Splicing Diagram

  8. Fiber Termination Distances • Fiber distances and network bandwidth determine networking infrastructure and equipment KINBER will implement

  9. Segment C Services

  10. Access Nodes • Original Plan vs. Today’s Reality • Access Node Build Out based on customer contracts • 22 Access Nodes have equipment to deliver services • 4 Access Nodes are fiber supported only • 3 Pass Through Nodes • 1 Dark Fiber Customer

  11. Current Adoption Rate

  12. Current Adoption Rate

  13. DWDM Topology

  14. Optical DWDM Network • 2-degree ROADM with Point-to-Point connections between Service Nodes • Some distances required amplification • 3 10G Waves are added and dropped at each Service Node • 8-degree ROADM in central ring between PSUP & WIND • Alien Waves or Transponders are used • 40 Channel CSM’s East and West

  15. Optical DWDM Network • All Service Nodes can deliver 10G Waves to other Service Nodes with no additional amplification or Regeneration • Erie to Philadelphia • Philadelphia to Pittsburgh • Pittsburgh to Scranton • Etc. • 100G Service is available from certain Service Nodes today without additional amplification or regeneration

  16. Core Topology • PE routers at every Service Node • Juniper MX-480 Chassis • (2) 4x10G MICs, (2) 20x1Gbps MICs • WindstreamCommunications, Penn State – University Park, 401 North Broad, and ACM • Now have capacity of (4)4x10G MIC • Router at ACM and 401 North Broad • MX-480 MPC with R cards • (1) 4x10G MICs, (1) 20x1Gbps MICs

  17. Core Topology • MPLS Core in the backbone • Resiliency and Efficiency • iBGP between each Service Node to facilitate L2VPN (VPLS) service • Route Reflectors at WIND, PSUP, SLIP, and LEHI • IS-IS between Service Nodes for Point-to-Point links • OSPF in the OSC for control-plane • Core is enhanced for quick-failover with • BFD • LDP Sync • ECMP

  18. Core Backbone

  19. PennREN Services • Point-to-Point (8 PtPs) • Point-to-Multipoint • Commodity Internet (11+G Subscribed) • Off-Net/On-Net Pricing • Transport to Internet2 Connectors (MAGPI, 3rox/Drexel) •  Merit Professional Learning • Member Exchange

  20. Commodity Internet • 10G Capacity in Pittsburgh and Philadelphia – 20G Aggregate • Upstreams are both with Cogent • Cost • Lack of Adoption to support the cost of diversification to date • Allow customers to peer to both routing nodes for value-added service

  21. Peering Relationships • ChescoNET – IU24 • PAIUnet Routes • Velocity Networks (Erie) • 3rox/PSC

  22. Member Exchange (KMEX) • Optional No-Charge Service • KINBER assigns IPv4 & address to Member • IPv6 coming soon • Peer with other Members directly or with Route Reflectors • Examples: • Lehigh University is using KMEX to get to MAGPI • PASSHE testing to Drexel for Internet2 • 12 Current Adopters

  23. Operational Perspective • Out of Band Circuits contracts with Earthlink Business include DOCSIS, ADSL, and T1 • Two head-end sites exist to get into the network for OOB access at Windstream and Allegheny Center Mall • Two Juniper SSLVPN units and SRX firewalls facilitate this access • GRNOC monitors and reports on equipment through 2 VPN tunnels into PennREN

  24. Operational Perspective • GlobalNOC handles Service Desk (Tier I) and GlobalNOC engineering handles Tier II Tickets • Escalation to Tier III is KINBER engineering • Business Hour Round Robin Assignment • After hours 2 week on-call rotation • Daily interaction between all groups through online chat room and weekly conference calls

  25. Operational Perspective • KINBER Engineering • Mike Carey – State College, PA • Dan Tomkinson– Roulette, PA • Andrew Kennerly– Conshohocken, PA • Ledcor Front-line Maintenance • 65 Hours/Month • Utilized for break fix and implementation

  26. Dynamo Workflow

  27. KINBER Engineering Priorities • Tier III Trouble Escalation • Implementation/New Business turn-up • Network Improvement • GlobalNOC Tool Enhancement • Network Changes and Improvements • Pre-Sales Engineering

  28. Current Projects • 3rd 10G Segment Backbone Upgrade • 5 Segments are now 30G • DDoS Appliance Testing • Routing Node Redundancy • Commodity Internet Diversification • Regional Incommon Pilot Program • Out of Band Version 3 • PennREN Technical Advisory Committee (PTACv2)

  29. Success Stories • Last-mile Connectivity • MAW Communications, Reading, PA • Velocity Networks, Erie, PA • Peering Relationships • Economic Development Network Designs • Access Node Turn-up to Date

  30. PennREN’s Future • Add more members, add resiliency to network • 100G Connectivity • New KINBER Services • 2nd Phase of KINBER Member Exchange • Develop the “StubHub” app for KMEX (Here is what I have, Here is what I want) • How can you facilitate collaboration within your organization?
