NKN Annual Workshop, IIT Mumbai, 31 st Oct -2 nd Nov 2012
Evolution of Network Management Systems Device centric approach 90’s Network Management meant device control and monitoring Mostly based on Simple Network Management Protocol (SNMP) Service and User centric approach 2000’s Has evolved into Operation Support System /Business Support System (OSS/BSS) Device centric approach is now the underlying layer
Network Management Related Standards TM ITU-T ITIL DMTF Forum IETF ETSI OMG • A single standard not enough to cover the management activities of heterogeneous networks • Combination of standards to be implemented as part of management systems

Major Challenges
Trends in Network Management Questions Can the systems manage themselves? which are trendsetters Can the systems adapt to changes of environment? Can the systems accept higher level directives from administrators and minimise human intervention? Can we change to Software Defined Networks and Open Flow Protocol? Can Network management be provided as Saas?
Autonomic Network Management Analyze Plan Knowledge Monitor Execute Managed Element
Policy Based Model Policies Policy Management Engine Monitor Configure Network
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
Energy Aware Network Management The basic objective of is to operate communication networks and other 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
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 .
