  1. OSS-BSS World Summit Trends in Service Assurance By: Kaynam HedayatCTO, EXFO Service Assurance Date: September 27, 2011

  2. What we do at EXFO Wireline network testing Wireless network testing Service Assurance Solutions for cost-effective deployment and reliable operation of high-speed wireline and wireless networks

  3. Trends in Service Assurance • Achieving End-to-End Service Assurance • Leveraging standards for cooperative SA with existing network elements • Integration of Probe and Performance Management Systems • Integration of service and network KPI’s • Intelligent Alarms • Expert analysis of events with rich root cause data prior to issuing the alarm • Into the Cloud • Service Assurance in the Cloud Service Assurance Service Management Fault & Event Management Performance Monitoring Probe Systems

  4. The Emerging Standards Model End-to-End Service Assurance through cooperation with existing network elements

  5. New Standards Supporting the Emerging Model • VoIP (for bVoIP, cVoIP, and peering) • RTCP-XR (IETF RFC3611) • NCS Loopback • SIP Media Loopback • SIP Publish/Notify • IP/MPLS & Carrier Ethernet • TWAMP (IETF RFC5357) • 802.1ag • Y.1731 • IPTV (for Broadcast, VOD, & Interactive Video) • TR-069 • TR-143 • RTCP-XR

  6. Case StudyLeveraging Standards in Mobile Backhaul 3G/4G Mobile Operator offering Ethernet Backhaul OLAs & SLAs MME/SGW/MSC Central Office Red Metro Ethernet Provider Tower 1 VLAN 101 Blue Metro Ethernet Provider Tower 2 VLAN 102 • Need independent assessmentof each circuit across two architectures • Non-stop Testing 24x7 of all Towers • Leveraging standard Protocols ITU-T Y.1731 • KPIs from MEF 10.2 • Availability, Loss, Delay and Frame Delay Variation • Report on Quality of: • Each Tower • Each Ethernet Provider Tower 3 VLAN 103 Tower 4 VLAN 104 Tower 5 VLAN 105 Tower 6 VLAN 106

  7. Integration of Probe & Performance Management Systems • Goal: provide correlated network and service performance KPI’s • Probe systems: provide the service view • Performance Management: provide the network view • Opportunity: one system to correlate KPI’s • Example: correlation of link utilization (network view) with link performance (service view) Service Management Fault & Event Management Performance Monitoring Network KPI(Utilization, CPU/Memory) Service KPILoss/Latency/Jitter802.1ag/Y.1731 Probe Systems Correlated Network & Service KPI

  8. Intelligent Alarms • The problem management process • Detect, know there is a problem • Isolate, identify where the problem is • Diagnose, determine the root cause of the problem • Recover, restore service if it is down or Repair, fix the cause • Validate, verify that the problem was fixed, and it does not come back • Problems Detected are sent to the Fault Manager via notification traps • Isolation Reports, Diagnosis Tools, and Repair Fixes are Launched from the Fault Manager • Provide alarms with rich context for effective isolation and diagnosis of service quality events

  9. Cloud Based SA
