Poor Man's Broadband

    << Previous | Main | Next >>

Poor Man's broadband addresses the paucity of Internet Bandwidth in developing countries. It is aimed at enhancing the accessibility and utility of the Internet in such regions. The basic idea is to use peer-to-peer (P2P) dialup connections to bypass the Internet when transferring large content between end-hosts.

In developing countries, e.g., Pakistan, the bottleneck is not the "last mile" (~40 Kbps over modem), but the Internet connection to the outside world (ISP limit of ~10 Kbps on average). Poor Man's Broadband circumvents this limitation by a P2P dialup architecture for accelerated "Internet access". This P2P dialup architecture essentially multiplexes scarce and expensive international Internet bandwidth over higher bandwidth P2P dialup connections within the country, building a Dial-up BitTorrent system (dubbed DitTorrent). Peers offer their resources for others. The resource is not only the downloaded blocks, but also the modem (and thus the connectivity) of the node.
