Evolution of Network Management Systems

Device centric approach Network Management meant device control and monitoring Mostly based on Simple Network Management Protocol (SNMP) Service and User centric approach Has evolved into Operation Support System /Business Support System (OSS/BSS) Device centric approach is now the underlying layer

90’s 2000’s

Network Management Related Standards

A single standard not enough to cover the

management activities of heterogeneous networks

Combination of standards to be implemented as part
f management systems

Major Challenges

SLIDE 12

Trends in Network Management

Questions which are trendsetters

Can the systems manage themselves? Can the systems adapt to changes of environment? Can the systems accept higher level directives from administrators and minimise human intervention? Can Network management be provided as Saas? Can we change to Software Defined Networks and Open Flow Protocol?

Policies

SLIDE 15

Policy Based Management for NKN

Formulate policies for various aspects including

Security Policies
Network access policy
Scope of control
Scalability
Traffic management policies
Traffic classification(audio, video, web etc)
Degrees of control (rate, bandwidth, congestion level etc.)
User/Application Identification
Alert notifications
Time and day restrictions
User restrictions ( allow, deny, restricted URLs)

Decide on the actions to be taken when an event or series of events happen Helps to automate the management process

SLIDE 16

Energy Aware Network Management

The basic objective of is to operate communication networks and

ther equipment with a minimal amount of energy

Provide means for reducing the power consumption of individual components of a network as well as of the whole network Instrumental in saving significant energy, if applied efficiently

Implement policies to achieve energy efficiency

SLIDE 17

Management Functions for Energy Management

Monitoring power states of network elements and their subcomponents Setting power states of network elements and their subcomponents Setting and enforcing power saving policies Autonomic principles can be applied for energy management by utilizing the monitor, analyze, decide and execute lifecycle for the activities.
