Municipal E-Government Metropolitan Area Network By Modular Design

Municipal E-government network, serving as a platform of national government extranet network to load practices from each district and city all over the country, aims to connect local government organization providing direct services to a detailed user, which is further linked to national government affair extranet network by extranet backbone network to construct a complete and national E-government network. It is the first place to construct a suitable E-government metropolitan area network (MAN) for different areas to meet their growing affair requirements considering the development and plan of E-government network in the coming few years. All of district and city, however, could only build E-government metropolitan area network gropingly and encountered many problems due to the absence of nationally clear and particular guidance.In this paper, a typical planning and developing of municipal E-government network is investigated preliminarily using a modular network design method. According to certain requirements of users, municipal E-government network can be divided into five modules for independent design, including intranet platform module, extranet platform module, server module, security proof module and network management module. This makes complex network planning simple, visual and easily accessible. When constructing, one independent module is subjected to a project team and then five modules could be performed simultaneously, significantly shortening construction period of E-government project and providing fundamental guarantee for speedy operation.This paper offers a design framework for locally municipal E-government MAN. Thereafter, deleting or/modifying modules could be used to quickly complete a MAN design according to user's requirement, which also favors copying by other cites.
