Advanced Signaling/Supervision and Routing Study.
Abstract
The work which was accomplished under the ADSS (Advanced Signaling and Supervision) effort resulted in three major outputs, as well as some results based on off-line analysis. (a) A simulation model prepared in the GPSS language, was designed and tested. This model represents a multinode communications network where the nodes can be characterized to accommodate various switching services. In addition, the structure of the model allows modification of the traffic mix to reflect different distributions, as well as changes in internodal trunking facilities. This has been accomplished by organizing the program into four major modules, Traffic Generation, Network Simulator (describing connectivity), a Path Calculator, and Statistical Reporter. The results of this model and its structure offer a flexible and useful tool for future switched network studies. (b) Three routing plans were tested with the use of the simulation. The two primary routing plans are Deterministic and Deterministic-Adaptive Routing Technique (DART); a modified version of the latter plan using a Calculated Path algorithm is also considered. Each of the above routing plans were tested in the context of a hierarchical and a non-hierarchical structure. (c) Digital signaling and supervision based on protocols developed within the study were developed and used for establishing call/message flow and control. (Author)
