“…More recent work to improve Internet usability in rural regions has been done by Chen et al [1,2]. In [1], an asynchronous queuing model was used where users can queue web requests as well as a cache search feature with predictive text.…”

The Internet is evolving from a system of connections between humans and machines to a new paradigm of social connection. However, it is still dominated by a hub and spoke architecture with inter-connectivity between users typically requiring connections to a common server on the Internet. This creates a large amount of traffic that must traverse an Internet gateway, even when users communicate with each other in a local network. Nowhere is this inefficiency more pronounced than in rural areas with low-bandwidth connectivity to the Internet. Our previous work in a rural village in Macha, Zambia showed that web traffic, and social networking in particular, are dominant services. In this paper we use a recent network trace, from this same village, to explore the degree of local user-to-user interaction in the village. Extraction of a social graph, using instant message interactions on Facebook, reveals that 54% of the messages are between local users. Traffic analysis highlights that the potential spare capacity of the local network is not utilized for direct local communication between users even though indirect communication between local users is routed through services on the Internet. These findings build a strong motivation for a new rural network architecture that places services that enable user-to-user interaction and file sharing in the village.

“…First, it has been observed that people in small communities in developing regions tend to have similar interests [14,17,32,43]. Second, the asynchronous web browsing model proposed in recent works [19,46] present an interesting opportunity to interject additional functionality into the web interaction loop not previously possible.…”

“…Caching in the context of developing regions: The body of literature regarding web caching is extensive, but caching mechanisms for developing regions have been explored only to a limited extent [9,14,32,34]. As web content becomes more fragmented and dynamic objects are commonplace, stale and nocache objects are already being cached by aggressive solutions to trade-off content freshness for availability.…”

“…However, if collaborative caching were included for these small communities, the cache hit rate dramatically rose to 80%. In 2010, Chen found (ELF dataset) that the cache hit rate at an urban school in India was only approximately 31.1% if nocache and stale pages were included [14]. Other caching works have focused on low cost hardware or specific network configurations [9,31,32].…”

“…However, in constrained situations where this is often not true, the estimated value of an object will be extremely inaccurate. We use the scenario in a previous work, Event Logger for Firefox (ELF) [14], to illustrate this problem. ELF is a Firefox extension that optimizes web page load times using aggressive caching (of somewhat stale contents) and prefetching while logging all requests.…”

We explore the limitations of existing caching mechanisms in slow networks and propose a new model of web caching designed for developing regions called interactive caching. Unlike conventional caching, interactive caching makes interacting with the cache the focus of web browsing when the connection is bad. Interactive caching achieves this by organizing the cache into topics for presentation to the user, optimizing for latency, and unaliasing cached content. In this paper we implement a prototypical version of interactive caching that includes: topic identification and presentation, a latency aware value function, DNS caching, and missing hyperlink suggestions. We evaluate our system based on a system implementation and web traces from multiple web cache deployments across different geographic locations in developing regions. We show how interactive caching can dramatically improve the user experience for slow connections by allowing users to explore the cache using trending topics that cover 60 -80% of requests and reducing page load times by up to 72.86%.
