  1. Connecting in the Wireless Networks ACE-RUS School & Symposium May 7, 2012

  2. Data-Centric Services

  3. Network Architecture Evolution

  4. Providing Wireless Backhaul Bandwidths • Copper • DSL • Fiber • FTTX • Direct Fiber • Wireless • Microwave • Millimeter-Wave

  5. Service Level Agreements • End-to-End Turn up testing and ongoing performance monitoring and reporting: • SLA • RFC 2544 / ITU-T Y.156sam • Equipment • DUT / SUT / NUT

  7. Applicable Codes • RFC 2544 • Throughput • Back-to-Back or Burstability • Frame Loss • Latency • System Reset • System Recovery • Y.156sam • Multi-Service Testing (Load Box) • Packet Delay Variation (Jitter) • CIR – EIR – Overshoot Rate

  8. A funny thing happened on the way to the Cell Tower • Verizon Wireless Performance Matrix • 4G Deployments will normally be 50 or 100 Mbps. • able to scale up to the full capacity of the GigE. • Committed bandwidth (non-overbooked) transport. • MTU size = 2008 bytes (802.3as) – (future 9000).

  9. MTU of Common Media:

  10. Timing

  11. Providing Timing • SyncE / IEEE-1588 • Ethernet Synchronization Messaging Channel (ESMC) • physical layer, hop by hop, similar to TDM networks. • Precision Timing Protocol (PTP) • Clock values passed inside the payloads. • Includes time-of-day synchronization. • IEEE-1588v2 • Establishes Master-Slave arrangements. • mitigates the effects of forwarding delays.

  12. NECA Tariff F.C.C. No. 5

  13. NECA Tariff F.C.C. No. 5 • Public Packet Data Network • Section 16.3 Ethernet Transport Service - ETS Channel Termination (300 foot delimiter) - ETS Port (Basic & Interconnection – 50 mile delimiter) - ETS Ethernet Virtual Connections / Extended / Interconnected - DSL Access Service Connection • Section 17.4 - Rate Bands - Service Levels - Monthly & Nonrecurring Charges
