Transcript

  • 1. March 2008 Booth 717 Carrier Ethernet Service Assurance: Test. Measure. Guarantee.
  • 2. Agenda
    • What is Carrier Ethernet?
    • Typical deployments and the importance of SLAs
    • SLA measurement methodologies and standards
    • Things to look for as you choose a Carrier Ethernet service assurance solution
  • 3. Carrier Ethernet Overview
    • What is Carrier Ethernet? 1
      • Carrier Ethernet is a ubiquitous, standardized, carrier-class service defined by five attributes that distinguish Carrier Ethernet from familiar LAN-based Ethernet
      • Service providers worldwide are migrating their existing networks to deliver Carrier Ethernet services to Enterprises, businesses, & residential end-users

  • 4. Carrier Ethernet Overview
    • Chief attractions of using Ethernet
      • Linear bandwidth scaling (10 Mbps to 10 Gbps)
      • QoS and configurable traffic policers provide fine-grained control of rates
      • Liquid bandwidth: ability to upgrade user access speed on the fly (no truck roll)
      • Less expensive than legacy Layer-2 technologies
      • Familiarity with Ethernet (ease of deployment)
  • 5. Agenda
    • What is Carrier Ethernet?
    • Typical deployments and the importance of SLAs

  • 9. Industry Research
  • 10. SLA Relevance
    • QoS & SLA requirements
      • Wide choice and granularity of bandwidth and quality of service options
      • SLAs that deliver end-to-end performance matching the requirements for voice, video, and data over converged business and residential networks
      • Provisioning via SLAs that provide end-to-end performance based on CIR, frame loss, delay, and delay variation characteristics
    • Service management requirements
      • The ability to monitor, diagnose, and centrally manage the network, using standards-based vendor independent implementations
      • Rapid service provisioning
  • 11. Agenda
    • What is Carrier Ethernet?
    • Typical deployments and the importance of SLAs
    • SLA measurement methodologies and standards
    • Things to look for as you choose a Carrier Ethernet service assurance solution
  • 12. High-Quality Carrier Ethernet Solutions
    • Turnkey Carrier Ethernet service assurance solution
      • Validate Ethernet install meets contract
      • Monitor the service
      • Troubleshoot when a problem is identified
        • Addressing QoS, SLAs, and service management requirements
    • Turn-up & 24x7 service monitoring
      • On-demand and ongoing tests for validation and troubleshooting of new services
      • Proactive monitoring through ongoing, periodic, and randomly scheduled tests
      • Real-time reports for turn-up, diagnostics, and performance baselines
      • Historical reports for operational monitoring, SLAs, marketing, and executives
  • 13. Ethernet OAM Standards
    • From MEF @ Globalcomm
    Status monitoring Performance management Performance monitoring with threshold alarms Link Trace Link Trace Fault isolation AIS AIS/RDI/Test Remote, local loopback Loopback Loopback (non-intrusive and intrusive) Remote failure indication: Dying gasp, link fault & critical event Continuity check Continuity check (keep alive) Discovery Discovery Discovery Transport/Link (802.3ah EFM) Basic Connectivity (IEEE 802.1ag,ITU) Services and Performance (ITU Y.1731/MEF)
  • 14. Standards & Technology
