ETSI EG 203 341

ETSI EG 203 341, "Approaches for Testing Adaptive Networks" defines a framework of testing principles and guidelines that may be used to test networks that exhibit some form of autonomic adaptive behaviour, which allows them to dynamically change their configuration, structure or operational parameters. The (re)-configuration is performed in response to stimuli such as changes in workload, operator policies that govern their operation, context (the network is context-aware and may have a degree of self-awareness); and challenges in the environment (i.e. conditions under which the network is operating, e.g. manifestations of faults, errors, failures in various parts of the network and its hardware and software components).

The functionality of individual components and basic interoperability can be ensured at design time. However, the complex interactions between various components or functions deployed in a live Adaptive Network (AN) may not be fully assessed or foreseen. Consequently, the document addresses methodologies to test ANs towards meeting their functional targets or policies, and ensuring a minimum trust level for autonomic operation of such networks.
