INTRODUCTION
The purpose of autonomic computing is to manage the complexity of networked components and systems.
First used to manage homogeneous components.
Later, extensions were defined to manage systems having heterogeneous components of differing capabilities.
Characteristics Of Autonomic Systems
Automatic :-This essentially means being able to self-control its internal functions and operations
Adaptive :-An autonomic system must be able to change its operation (i.e., its configuration, state and functions).
Aware :-Awareness will control adaptation of its operational behaviour in response to context or state changes
Operations
Sensor: Sensors retrieve vendor specific data, which is then converted to a normalized form and analyzed to determine.
Effectors: Appropriate actions are executed using effectors that translate normalized commands back to a form that the managed resource(s) can understand.
Autonomic Networking Approach
Autonomic networking must deal with three different types of heterogeneity
Different devices having different functionality.
Different devices that use different languages, data, and commands to represent the same concept.
Different types of control mechanisms that must be coordinated (e.g., wired and wireless devices are managed using different protocols).
