The network devices and services are becoming more complex and management task for all these devices and services are not easy from a single point. Different services may need to be coordinated in order to meet user or service requirements. Directory Enabled Network (DEN) could be used to help easy management of a network instead of managing individual resources and services. Directory Enabled Network gives us an Information Model to design an interoperable, distributed, and robust directory service for accessing network applications, services and resources in a platforms independent manner. An implementation of Directory Enabled Network is a client/server application between directory user agents and directory service agents. Today's networking environment composed of a large number of network elements, and the networking environment is changing frequently. The functionality and services provided by network element depends on directly or indirectly on the environment on which the network elements operate. In other words, the network environment affects ontological purpose of network elements. Using formally defined Directory Enabled Network ontology could assist both directory service agents and directory user agents to work consistently with network elements in the constantly changing environment. But, less attention is given on studying Directory Enabled Network from ontological perspectives using any formal approach. This study provides a detail framework for the Directory Enabled Network implementation from ontological perspectives in an enterprise. In order to clarify the DEN classes and their relationships as well as explaining the ontological nature of Directory Enabled Network, different networking resources and services that exist in CSIM network are presented as examples. In order accessing a variety of directory and naming services transparently from the Java application, Java Naming and Directory Interface (JNDI) is recommended as a programming interface in Java programming environment for implementing DEN ontology. This thesis can also be taken as a case study of Directory Enabled Network for CSIM Network, which illustrates the initial considerations to implement Directory Enabled Network in an enterprise.
