The information layered architecture model,layers, methodology and their application for service activation

The authors propose a model (information layered architecture ILA) forTMN layering, that is based on grouping managed objects that share a common information perspective. The model provides an interfacing mechanism between layers that is based on referencing techniques between managed objects. We identified four levels ofTMN abstractions that can be used to represent a wide range of telecommunication processes. These are : customer, service, network and network element management. We then use the ILA to develop a model for the process of service activation. By doing so we demonstrate how modelling can be used as a technique to manage complicated processes.
