Over the past few months I’ve been watching news that is emerging from think tanks, independent researchers, and news analysts about the ‘dramatic’ increases in bandwidth usage in North America. In this post I’d like to pull together a host of sources on the recent use of the UDP protocol for transferring files, and how that relates to bandwidth scarcity. Over the next month or so, I’m hoping to put together some additional pieces on packet inspection, Enhanced Drives Licenses (EDLs), and more topical IT and privacy issues. But first, to UDP data traffic…
Peer-to-Peer and Link Points
This summer Bell Canada argued that they needed to use Deep Packet Inspection (DPI) devices to stem the use of peer-to-peer (P2P) applications during peak usage time, because P2P applications were causing congestion at major link points along Bell’s network. Bell’s practices became an issue when the Canadian Association of Internet Providers (CAIP) filed a complaint with the CRTC; Bell’s traffic shaping was being applied to all traffic that ran along Bell’s ADSL lines, rather than being localized to Bell’s customer.
