This paper introduces the concept of a process model for network engineering and operation, which addresses quality, process, and maturity of the network engineering process. Currently, the state-of-the-art in network engineering may be classi ed as less than formal. The need for a well planned and exercised network engineering process model is essential for the proper growth of the network engineering practices. The current state of the network engineering process is akin to the software process of more than a decade ago. The network process model, proposed here, demonstrates steps that are modeled as a well-de ned process, much like the process notion of software engineering, however, utilizing its own set of processes areas and key practices. In this work, the`quality' of the network engineering process is introduced through the use of a Network Maturity Model NMM, from which an organization's maturity i.e., level of advancement in the design, development and deployment of networks can be evaluated and quanti ed. The objective is similar to the Capability Maturity Model CMM 2 developed by the Software Engineering Institute SEI, which is used world-wide by government and industry to evaluate the level of maturity and quality in the software engineering capabilities of di erent organizations.

This paper demonstrates the capability and use of integrating multimedia tools and events in the lifecycle development of large, complex networks. Network Engineering (NE), detailed by the authors previous research, defines process steps for the requirement specification, design, evaluation, testing, layout and maintenance of computer networks. This paper shows that the integration of multimedia in the process steps for NE results in better networks being designed.The paper details a multimedia based simulation executed on the network prototype, prior to submitting the designed network to a more rigorous simulation software, like OPNET (Optimized Network Engineering Tools). The tool detailed in this paper allows the user to specify events during the network simulation. Events are user defined conditions that can identify and alert the user regarding abnormal behavior of the network system. The key ideas presented in this paper include the usage of multimedia in the NE process, and the role of user-defined events in identifying design aspects of the network.
