4. Importance of Network Operations and Control
Who needs to run a network?
Home network: all of us 
Broadband network: Telstra, Optus
Mobile network: China mobile (851.2m subscribers!)
Content provider: Google, Netflix
Cloud operator: Amazon
CDN (content distribution network): Akamai, Limelight
Game operators: Steam/Valve, Electronic Arts, Ubisoft, Epic
How have network traditionally been built and operated?
Managing devices (switches, routers)
Does it scale? How many humans are needed to configure 10,000 switches?
Automation / programmability for management and control
Data-plane is also becoming programmable!
1-3

5. What is network management?
autonomous systems (aka “network”): 1000s of interacting hardware/software components
other complex systems requiring monitoring, control:
jet airplane
nuclear power plant
others?
"Network management includes the deployment, integration
and coordination of the hardware, software, and human
elements to monitor, test, poll, configure, analyze, evaluate,
and control the network and element resources to meet the
real-time, operational performance, and Quality of Service
requirements at a reasonable cost."

6. Course Objectives Basics of managing a data network
Organizing, communicating, and monitoring management information
Old way: MIB, SNMP, RMON
New way: YANG models, REST APIs, software automation
Network management functions (FCAPS):
Configuration
Performance
Fault
Security
Accounting
Practical project work on real-world platform

7. Why do we need Network Management?
Detect and fix problems:
Power/interface failures
Hosts/router software crashes
Bad cables
Routing flaps
Monitor network to aid in resource deployment and identify potential problems
Configure services
Monitoring for service level agreements (SLAs)
Secure the network (e.g. intrusion detection)
Bottom line: keep the network up and running properly!

8. Many functions!

9. Functional areas (ISO model)
Configuration management
Keep track of devices
hardware/software configurations
Fault management
Detect / isolate failures, restore service
Trouble-ticket administration
Performance management
Quantify, measure, report, analyze, control performance
Traffic volume, delay, services (DNS, web/mail server)
Security management
Control access to network resources
Firewalls, secure communication, authentication
Accounting management
Log and control access to network resources
Quotas, Charging, access privileges

10. Evolution of Network Management
Early days: small network
ping and trace-route suffice
1980’s: OSI developed CMIP framework
Too complex, lost to Internet SNMP framework
Mid-90’s: realization for a systematic approach to network management
80% of OpEx on network management!
2000’s: hundreds of NMS tools
Critical to complex networking systems
Well-paid network management jobs!
Present-day: automation, programming!
Models, APIs needed to scale in size
ML/AI being applied to complex networking systems
Network management: combination of art and science
