Internet access in developing world countries is both extremely slow and expensive, due largely to a lack of physical infrastructure. As a result, web caching—wherein a central web cache stores data fetched by users in the network and provides subsequent requesters with a cached copy of that data—can be effective in decreasing the lag users experience in these regions. Paired with another strategy called “bandwidth shifting,” in which an accelerator node located in a high-bandwidth region compresses data for and manages the freshness for accelerator nodes in low-bandwidth regions, caching can be more effective still. I was curious to know if these sophisticated acceleration techniques could run on a cheap, single-board ARM computer, which could ultimately provide a simple plug-and-play platform for developing world network accelerators. In my research, I attempted to create such a platform on a BeagleBone Black (BBB), a $45 Linux computer no larger than a credit card. After testing the BBB’s bandwidth in serving disk requests, I determined this cheap computer would have the chutzpa to serve as a web cache, and began developing caching/bandwidth-shifting software for it. Using Node Javascript and C, I created a portable software stack that could run on the BBB, resulting in BeagleCache: A Low-Cost Caching Proxy for the Developing World.
