Service location tradeoffs in intelligent networks

Intelligent Network (IN) architectureplanners envision many different kinds of network structure to provide service offerings. These structures vary from arrangements where service logic is located in the switch to those where it is located in a Network Element (NE) physically remote from the switch. This service logic is expressed through Service Logic Programs (SLPs). SLP placement in one, or several of a wide variety of locations is considered. This paper analyzes different classes of service, identifies their characteristics, and presents tradeoffs to be considered in the implementation of individual services. In addition, considerations of the effects of service descriptions and groupings, as well as service performance, economics, dependability, operations support, and billing needs on SLP placement are included.
