Abstract

When designing an autonomous network one of the key problems is the strategy of decision making and teaching the autonomous entities. Current approaches propose a static method (predefined knowledge) or per device artificial intelligence. A new approach will be presented that makes use of techniques that humans use - rated forum as a means of gathering all available knowledge. The method introduces concepts like: knowledge recorder, knowledge forum, solution rating (positive and negative), autonomous moderator. An enablement is proposed that build on existing knowledge based techniques.

ABSTRACT

When designing an autonomous network one of the key problems is the strategy of decision making and teaching the autonomous entities. Current approaches propose a static method (predefined knowledge) or per device artificial intelligence.

            A new approach will be presented that makes use of techniques that humans use – a rated forum as a means of gathering all available knowledge.

            The method introduces concepts like: knowledge recorder, knowledge forum, solution rating (positive and negative), autonomous moderator. An enablement is proposed that build on existing knowledge based techniques.

PROBLEM

In autonomic networks with autonomic managers some of the managers may have more knowledge about the network (better trained, longer in the network, etc) while the other managers may have less knowledge about the network. Moreover some of the managers may have knowledge limited only to the cases from their proximity (closest neighborhood).

The problem is with efficient knowledge exchange between autonomic entities – that the less mature ones can re-use solutions that were proven efficient in the past. Moreover – the entities can evaluate impact of the solution before applying them to the network. It is also critical that the knowledge exchange mechanism allows solution mutations.

 

SOLUTION

First of all a concept of knowledge recorder is introduced. This would be a module capable of recording a semantic history of the network (autonomic system) – in terms of states, changes, events, etc.  It would represent this history at several layers of abstraction (corresponding for example to policy continuum layers), but focused on upper layers - so device/vendor/instance independent. It would serve to the network devices with semantic analysis of events (or sequences of events). It would be continuously analyzing gathered data seeking for common patterns. However it will be a passive entity – neither enforcing nor triggering any actions.

On top of the knowledge repository a knowledge sharing forum should be built. This forum would be used by autonomic managers within the network. Forum is a list of problem solutions submitted by autonomic agents previously when they had to resolve a problem. Moreover it contains solution ranking - how good is a particular solution in problem recovery. Forum is linked to knowledge base – so problematic patterns in the network history are mapped (if possible) to potential solutions in the forum.

Whenever the autonomic manager has a problem to be solved – it queries knowledge for...
