Transcript of "ptcl noc Introductry concepts -_lecture___1"

  1. 1. 1
  2. 2. PTCL National NOC (Network Operations Center) 2
  3. 3. Why NOC? What is NOC? •It is Network Operations Center • It is an apex in TMN hierarchy to view, monitor and control networks. •It is a tool for managing a network of networks. 3
  4. 4. Why NOC? What is NOC ? •NOC rely on a set of Operations Support Systems (OSS) and operations procedures to manage the networks. •The OSS collects fault and performance data from the Element Management Systems and Network Elements and present them in standardized manner to enable the NOC staff to monitor and manage the networks. 4
  5. 5. Why NOC? What is NOC ? • NOC is a cross-domain organization managing network across several business and operations units at PTCL. It manages networks provided by multiple vendors, multiple network technologies in multiple geographic locations. Using a set of standardized processes and tools, regardless of where in the PTCL infrastructure the problem lies, the NOC aims to • • • • 5 provide up-to-date status of services. identify and minimize impacts to customers due to service outages. manage resolution of outages in a timely manner be a focal point for coordination during major networks related events
  6. 6. Centralized NOC?    6 Integrated EMSs Trouble Ticketing Integrated Network Management Fault Centralized Network visibility
  7. 7. Why NOC? Current Operational Challenges Decentralized Network Management Reduced visibility of outstanding/critical problems More time taken to own and record the faults Manual activity logs No knowledge base being maintained to track faults 7
  8. 8. Why NOC? No Trouble Ticketing system No Automated Escalation process No Access controls defined for operators No Centralized Work Orders Platform Service provisioning to customers is distributed and has inherent delays. 8
  9. 9. Why NOC? TMN Hierarchy Business Management Layer BML SML Service Management Layer NML Network Management Layer EML Element Management Layer NEL Network Element Layer 9
  10. 10. Why NOC? NOC provides FCAPS functions for networks – Fault management – Configuration management – Account management – Performance management – Security management 10
  11. 11. How NOC will help PTCL in achieving its targets? NOC will proactively identify and get resolved the faults in Network through Real time Network Monitoring Network status visibility Increase network availability Enhanced QOS visibility Centralized Reporting Uniform performance statistics Optimization of operational and maintenance cost Centralized level of O&M/OSS management Standardized Operational Processes 11
  12. 12. PTCL NOC scope- at Present • • Performance management • 12 Alarm monitoring & management Trouble Ticketing (Incident management)
  13. 13. Networks – Some basic concepts Network Element (NE)? Element Manager System (EMS)? Network Management Systems (NMS)? A cluster of NMSs Examples in Transmission and Switching Domains 13
  14. 14. Alarms and their classifications What are Alarms? • The EMS generates notifications regarding events on N.E.s called alarms. • The events in a networks can be; Network Faults Performance events • The alarms contains information (alarm attributes) regarding: Begin time, End time, Rack, Shelf, Slot, Port etc 14
  15. 15. Alarms and their classifications Classifications of Alarms? • Severity Critical Alarms Major Alarms Minor Alarms Warnings • Type: Equipment Alarms Communications Alarms Environment Alarms QoS Alarms Security Alarms 15
  16. 16. Alarms – Some Concepts • Alarm Attributes (Managed object, Raising time, clearing time etc) • Alarms & Clear Alarms • Severity Propagation of Alarms • Similar Alarms (Managed Object, Alarm type, Specific problem, Probable cause) 16
  17. 17. Examples of Alarms 17
  18. 18. Examples of Alarms 18
  19. 19. Examples of Alarms 19
  20. 20. Alarm collection Processes The North Bound Interface (NBI) – This is an interface on EMS with standardized set of protocols for information interchange with NMS. The commonly used NBI Protocols – CORBA – ASCII – SNMP – Q3 20
  21. 21. NOC OSS Capacity 21
  22. 22. PTCL network - Classification The PTCL network is multi functional, multi vendor network, and can be classified as fallows : – Transmission network Core network (Backbone) Access network (Junction and OFAN) – Switching network Core network (Transits ) Access network (RLUs) 22
  23. 23. PTCL network - Classification – WLL network Core network (MSCs) Access network (BTSs) – Signaling network – Synchronization network – NGN network – IN network – IP network (PIE) – Multimedia and Broad Band network – DXX network 23
