In fact, when the search space is reduced, the runtime of the plan is decreased, thus guarantying the speed of the implementation of the service restoration.
It wasn't the VoIP technology, I'd used loads of other VoIP apps before, it was the implementation of the service.
For the implementation of the service directory we have existing basic technologies that are open source and therefore compatible with the π-Cloud idea.
The implementation of the service is based on a SNMP MIB (Management Information Base) called fdMIB (failure detector MIB), which can be easily integrated to distributed applications.
Once the implementation of the service graph with the lowest cost has been found, the service graph subsets are sent to the individual network manager of the Titan nodes for execution.
As shown in Fig. 1, supposing that one fault has taken place at point B, Area2 is the downstream un-faulted area and TS2 is one of the candidate switches for the implementation of the service restoration.
Supposing that one fault has taken place at point A. Therefore, Area 1 is the downstream un-faulted area and TS1 is one of candidate switches for the implementation of the service restoration.
Aware that John used the mentioned pattern, Paul, the developer, may look for an implementation pattern which complies with John's choice and assists the implementation of the service components, through the service builder; in this case, he uses the 'DVD Delivery' guideline along with the 'web delivery (IPT)' pattern.
Furthermore, technology lock-in regarding the implementation of the service layers was also addressed by using AndroMDA, as the implementation of the service facade can be switched during the build process from Spring based components to distributed Enterprise Java Beans.
Future evaluations of complex interventions should be initiated prior to the implementation of the service, and would benefit from an enumerable sampling frame and a measurable baseline.
