  2. Differentiate at Customer Touch-points – Service Life Cycle “Before I start paying” “While It’s working” “When something is not working…” Source: E&Y 2010

  3. Reliability of L2 ServicesHW Based OAM mechanism Layer 2 Services Must be transparent and dependable

  4. Fault Management Isolation with Layer 2/3 loopback “Loopback packets which have VID 100 & IP SA 117.155.160.13 + perform IP & MAC swap” “Send a packet with VID 100 and IP SA 117.155.160.13 12 and wait for a reply • Supports L2 or L3 loopbacks up to line rate • Can be used for throughput testing across routed/switched networks. • Flexible loopback criteria: • Src\Dst MAC, Src/dst IP, VLAN, p bit, DSCP, etc. • Vlan+Mac, VLAN + IP, Vlan+Pbit, etc. • Non-Intrusive loopback on a dedicated flow – always “on” , with no need to configure the remote NTU • Ability to loopback many flows simultaneously (on both user & network sides) Network Tester Carrier Ethernet NID ETX-204A

  5. Summary of available Ethernet OAM mechanisms Performance Mgt. AccuracyDelay Measurement Branch A Real Time Headquarters PE UNI EVC Priority Data Hardware based OAM Micro-seconds accuracy Best Effort Real Time PE Priority Data EVC 1 PSN Best Effort Branch B EVC 2 Real Time IP DSLAM Real Time EVC Priority Data Priority Data Best Effort Best Effort UNI • SW Based OAM Example • CPU reaction time: 1ms, variance of 2ms • Delay accuracy of 2ms - typical SLA at 1ms • HW based OAM: A few micro seconds

  6. Summary of available Ethernet OAM mechanisms Performance Mgt. Accuracy Frame Loss Ratio Branch A Real Time Headquarters PE UNI EVC Priority Data Hardware based OAM Micro-seconds accuracy Best Effort Real Time PE Priority Data EVC 1 PSN Best Effort Branch B EVC 2 Real Time IP DSLAM Real Time EVC Priority Data Priority Data Best Effort Best Effort UNI • Synthetic Based OAM Example • - 20Mbps service, 1500 frame size results in ~1600 PPS • Approx. 0.01% packet loss and required +/-0.1% error • 70 days of measurements are required • Non-synthetic, HW Based mechanism is immediate

  7. On-demand Throughput Testing Traffic Generation Branch A Real Time Headquarters • Line Rate Traffic Generator • Concurrent Multiple CoS • L2 path as the service • Data integrity testing - PRBS • Create a “birth certificate” at service turn-up • Provide customer with report before service starts • Confirm troubleshooting has succeeded • Period testing for: Preventive maintenance & capacity planning ETX PE UNI EVC Priority Data Best Effort Real Time PE ETX Priority Data EVC 1 PSN Best Effort Branch B EVC 2 Real Time IP DSLAM Real Time ETX EVC Priority Data Priority Data Best Effort Best Effort UNI

  8. Differentiate at Customer Touch-Points – Service Life Cycle Connectivity Verification Performance Monitoring Fault Detection & Isolation • Ethernet OAM - 802.1ag • Continuity Check • MAC Ping • Ethernet OAM – 802.1ag • Continuity Check • Loopback • Link Trace • Ethernet OAM – Y.1731 • Frame Delay, Frame Delay, Frame Loss • Service availability (G.826) SLA Threshold Reporting Diagnostic Loopbacks Fault Propagation & Notification • Defining SLA objectives and proactively notified when crossed • Alarms and traps on management system • Loopbacks • L1 physical interface loopback • L2/L3 Loopback per flow with MAC/IP swap (up to line rate) • Ethernet OAM – Y.1731 • Per EVC ‘Forward’ and ‘Backward ’ Alarm Propagation (AIS and RDI) • Dying Gasp indication to active - 802.3ah • Per port Alarm Propagation SLA Verification Testing Statistics Collection Reporting Resiliency & Repair • RFC-2544 based tests • Throughput, Loss and Delay tests • Data integrity tests (BERT) • Delay Measurement • Linear Protection ( “EVC Protection”) - G.8031 • Ethernet Ring Protection - G.8032 • port protection based on Link Aggregation - 802.3 (formerly 802.3ad) • Collecting SLA statistics • Statistics collection via SNMP or FTP • Statistics can be used to generate SLA reports • Managing the Service life cycle is essential to control the OpEx
