Today’s routers have increasingly short life cycles. The short life cycle is due to the growing demand for bandwidth by users. High traffic under limited bandwidth conditions results in a significant number of dropped connections and excruciatingly slow speeds. Coupled with the practice of sporadic firmware updates for the majority of commercial routers, consumers usually have to purchase new hardware every two years to maintain consistent speeds. This project explores an alternative, building a home built router suitable for use in senior projects and special projects. While our lab has made use of a “specimen” router built from an aging Dell Computer in the past; while this router has worked quite well when needed; it was decided to initiate a formal work that built home-built routers. The hardware basis of these is the PC. The PC runs a Linux distribution OS. The paper reports the building and configuration steps. The performance of the router is compared to existing devices and reported.
Objective test measurements include total transaction size, transaction rate, throughput, total elapsed time, response time and the number of failed transactions. Test conditions vary by changing the number of “data” sources. The router is increasingly stressed as the number of sources rise. Tests of the networks containing the home-built routers and commercially built routers were done and reported.
Real traffic testing was also done, with clients establishing data streams between themselves and multiple in-house web servers. This test-bed provided a test bed for subjective testing. A Likert scale was proposed and implemented for the study. Tests of the networks containing the home-built routers and commercially built routers were done and reported.
The work also reports the cost of material for the home-built routers. Since the home-built routers do not implement a pseudo-Cisco IOS, they are not suitable for teaching Cisco Academy content. However, the home-built routers do implement well-understood router functions and capabilities. A review of these appears in the paper for completeness.
