Low-cost Highly-interoperable Multiplatform Campus Network: Experience of YARSI University
To some organizations, building campus network is sometimes considered to be very expensive; and this has made the project uneasy to perform. Moreover, if the organization without sufficient IT knowledge does not have capable IT engineers, leaving this project to third parties without supervision would lead to unexpected larger expenses. For this reason, in the year of 2003, YARSI University formed CMIS (Center for Management Infor-mation System) to perform tasks in designing, operations and maintenance of campus network and its services. By combining Open Source operating system run on a local assembled personal computer as gateway and router, and switching technology from Cisco, we designed a low-cost UTP-based campus network which covering rooms and buildings in YARSI environment. Meanwhile the internet access through several broadband connections and dedicated wireless was shared to more than 100 simultaneous users by a captive portal system. With this strategy, we can significantly reduce cost for purchasing, maintenance and operations of network infrastructure and internet access. Our model in designing low-cost campus network and internet connections could be adopted by rural community or organizations that have limited budget to have internet access.
