12. Web-Based Enterprise Management

13. WBEM based on Common Information Module, developed by Microsoft CIM is information-modeling framework intended to accommodate all protocols and frameworks Object-oriented Five components: Web client CIM object manager (CIMOM) CIM schema Management protocol Managed objects with specific protocol

14. Microsoft WMI

15. WMI is Microsoft infrastructure to support WBEM CIM WMI comprises management infrastructure, applications, and agents CIMOM has plug-in management applications COM/DCOM API specifies interface to CIMOM CIM is the CIM schema Object providers are management agents (e.g. SNMP agent)

16. Service Driven Network Network of services (instead of network of components) based on Java technology and thin clients. It speeds up service creation and deployment, as well as handling provisioning, management and billing. Dynamic Management The Service-Driven Network enables you to reconfigure the infrastructure of the network dynamically, by pushing services in real-time, both to the network infrastructure elements, and to consumer devices across the Internet. Java technology calls plug-in JavaBean MBean is management JavaBean

17. JDMK - Java Dynamic Management Kits

18. JDMK Java dynamic management tool kit to build Java-based NMS MBean is an intelligent agent; does not need polling as in SNMP agent JDMK library of core management services implemented as MBeans Java Dynamic Management agent comprises MBeansMBeans: core management framework, MBean server Protocol adaptorsProtocol adaptors: interfaces to applications

27. Looking Ahead Future network and system management frameworks should accommodate well-established SNMP entities Web agents are intelligent and future points to the use of Web technology Web-based management offers two options WBEM is comprehensive and centralized approach to enterprise management; accommodates both scalar and object-oriented schemes JMX is decentralized and uses Java technology; agents embedded in objects and can be downloaded from NMS; platform independent Future NMS environment could be a merger of the old and the new - at least in the near future
