Introduction

The planning and cost-modeling of large-scale computer Wide Area Networks (WANs) are important issues for carrier service providers, Internet Service Providers (ISP), and for large enterprises that use WANs. In this research, we develop several quantitative and business-oriented cost models that define the mathematical relationships needed to derive the cost estimate of a set of current WAN transmission technologies including: digital private lines, Frame Relay, ATM, ADSL, VSAT, and VPN. In addition, the research presents a cost-effective methodology for planning a large scales WAN.

Wide Area Network

A Wide Area Network (WAN) is a data communications network that covers a relatively wide geographical area. WAN often mixes various transmission technologies, and uses transmission facilities provided by common carriers. Building such a network is a overwhelming task due to the large financial investment needed, and the large array of technological and design options to be investigated. In addition, much expertise, up-to-date knowledge and great practical skills are required to construct a design that is fit for purpose, some of which may not be available to the design team. Another difficulty arises from the fact that there is no standard process for WAN design or for the implementation of WAN internetworks. For all of these, having a cost effective design and good planning for WAN development and implementation are essential.

Phase 1- Definition of requirements: This phase identifies the traffic generated at each network node as well as from remote users, plus traffic across the inter-node links.

Phase 2- Topological design: In this phase, once the traffic requirements and services statistics are compiled, and relevant operational and business-related data are identified, the new network topological design is evaluated.

Phase 3- Cost analysis: In this phase, an analysis of the network cost is performed, based on an understanding of the network ...
