Towards Service Awareness and Autonomic Features in a SIP-Enabled Network

Next-generation communication infrastructures can become autonomic only if they can leverage some form of awareness about themselves and the services they deliver. Such awareness can be reached by disseminating across the network a proper amount of multi-faceted knowledge. We have started to identify a set of basic capabilities that provide a degree of service-awareness and enable various autonomic behaviors, oriented towards sustaining communication services within a SIP-enabled network. We have designed network features that support those capabilities, in particular focusing on awareness features relevant to service deployment, monitoring and exposition, and we have built those features natively into the control plane, relying upon the SIP Event Framework specifications. We have also defined a set of scenarios that exploit the service awareness introduced in the network for various autonomic purposes.
