Ett ramverk för arkitektoniska vyer : En "4+1" modell för dokumentation av ett företagsnätverk

Sammanfattning: Network documentation is often a low-priority task at many companies. Despite this, there are many benefits that should be considered against the fact that it is a comprehensive job. Good network documentation can provide companies the opportunity to reduce dependence on individuals, take proactive decisions and save money. Network documentation mainly consist of physical and/or logical topology descriptions that describes the logical and/or physical layout of the network. These so-called architectural views focus on technology rather than the services and features that the company's network provides. To simplify communication between stakeholders with different areas of knowledge, e.g. between an engineers and corporate management, I propose a model that complement traditional visual description of a network. With the help of viewpoint frameworks such as Kruchten's "4+1" model, I want to visualize relationships between corporate services, business processes, applications and the underlying infrastructure. A qualitative case study at a company with needs of network documentation has resulted in a prototype, a viewpoint framework, based on concepts of enterprise architecture. Analyzing a use case together with the prototype demonstrated that the prototype can visualize relationships between different layers in an organization. The prototype can be used as a starting point or guidance for those who want to document architecture of an enterprise network. The prototype can serve as means of communication in order to justify the investment that in turn ensures a modern energy-efficient operating environment that creates conditions for sustainable information- and communication technology.
