Web-based Network Management

• Classic Web-Based Network Management (WBNM) is the ability to monitor and actively manage a network through the Browser User Interface(BUI), display technologies for network management.

• But recently great advance in Web technologies make it possible to construct new management framework including Information Modeling, Management Protocol

CORBA-based Network Management

• CORBA-based Network Management is a design and implementation approach for an open, standards-based, extensible, and distributed network management using CORBA.

• Its main application area was Telecommunication network based on TMN, but recently new approaches begin to report such as an pure CORBA approach, SNMP implementation alternative and integration with Web technology

Home Network Management• Home Networking is the collection of technologies and services that

make it possible to connect multiple computing and information devices at home. Home networking ushers in a new era of entertainment and convenience for consumers. The most successful and useful home networks will be simple, reliable, secure, and inexpensive: Mega Trend

• Characteristics• No administrator: Plug and Play, Self configuration, Auto recover

y• Easy of use: system to service management

Mobile Agent and its application in Network Management

• Mobile agent is an autonomous software entities that behave in accordance with self-contained intelligence (knowledge and inference) while moving network

• intelligent agents and particularly mobile agents have a great potential to influence the design of future network management, since they represent an alternative to the traditional client/server interaction model

Policy-based Network Management

• PBNM provides the ability to define and distribute policies to manage heterogeneous networks. These policies control critical network resources such as bandwidth, security and Web access.
