Network Reliability: Data Reporting & Analysis for Packet Switching

This focus group will evaluate the reliability of public telecommunications network services in the US, including packet-switched networks. It will monitor a voluntary reporting program and analyze outage data to assess efficacy and ongoing reliability.

  1. Focus Group 2.B2Network Reliability - Data Reporting & Analysis for Packet Switching NRIC V Council Meeting - June 26, 2001

  2. Membership 2.B2 - Data Reporting and Analysis Team

  3. NRIC V Charter2. Network Reliability. • (a) The Committee will evaluate, and report on, the reliability of public telecommunications network services in the United States, including the reliability of packet switched networks. • (c) During the charter of the previous Committee, interested participants recommended that the FCC adopt a voluntary reporting program, administered by the National Communications System, to gather outage data for those telecommunications and information service providers not currently required to report outages. The Committee will monitor this process, analyze the data obtained from the voluntary trial and report on the efficacy of that process, as well as the on-going reliability of such services.

  4. NRIC Voluntary Trial Criteria

  5. Examples of Incident/OutageCritical Event Failure • Access failure (dialup, DSL, cable) • 30,000 or more customers for 30 minutes or more • Separation failure • 2 non-redundant OC48s fail for 3 hours • Routing failure • Advertised default route - April 25, 1997 McClean, Virginia • DNS failure • NSI partial update of DNS routers with corrupted data • Denial of Service attacks • Microsoft • Yahoo

  6. Commercial Internet - Other Efforts • T1A1.2 • 2000-051Measuring the Reliability/Availability of IP-based Networks and Services Using Defects per Million (DPM) • 2001-028 Defects per Million as a Measure ofIP Network Reliability Part 1: Access DPM • 2001-002 Draft Technical Report on Reliability/Availability of IP-based Networks and Services

  7. Commercial Internet – Other Efforts • Internet Engineering Task Force (IETF) • Measurements and Metrics • RFC 2330 Framework for IP Performance Metrics (IPPM) • RFC 2679 A One-way Delay Metric for IPPM • RFC 2680 A One-way Packet Loss Metric for IPPM • RFC 2681 A Round-trip Delay Metric for IPPM • RFC 2678 IPPM Metrics for Measuring Connectivity • DNS Specific Operations • RFC 3007 Secure Domain Name Service Dynamic Update • RFC 3130 Notes from the State-Of-the-Technology:DNSSEC • RFC 2930 Secret Key Establishment for DNS • RFC 1912 Common DNS Operational and Configuration Errors

  8. Next Steps • Determine reportable event criteria • Catalogue efforts of others • “Standards” bodies • T1A1 • IETF • Other groups • Packet cable • CompTIA • Service Level Agreements • Measure and report reliability • Publicly available “external” information • Keynote • Boardwatch • Internet Weather

  9. Next Steps, cont. • Phase 1 • General Public Internet Connectivity • Phase 2 • Commercial Frame Services • ATM • Frame Relay
