Nature of torrent traffic
Torrent traffic is a big headache for network administrators and broadband service providers. Torrent traffic consumes between 30 to 70% of internet bandwidth, becoming single biggest expense for service providers.
Most of the traffic on the torrent network is repeated in nature. About 70% of the torrents are trending traffic. i.e. at any given point of time, there are certain torrents that are repeatedly downloaded by various users. Of the remaining, 20% traffic is for recently trending traffic remaining 10% fall in the category of nostalgic.
Caching as a concept has been around for a lot of time. Almost all service providers use web caching to improve web browsing experience. Recent addition to this is youtube caching.
But torrent caching has been very difficult to analyze. In order to avoid detection, torrent protocol has been developed to use encryption. Such detection could be used by service providers to block torrent traffic.
xCache Torrent Caching Engine
xCache is a torrent caching engine that works like web caching engine like squid. When first time any given torrent is downloaded by any user, xCache keeps a copy in the server. Next time any user requests for the same torrent, xCache connects to the user and delivers the cached content.
Cached content is delivered at wire-speed giving exceptional experience to the user. This saves about 30-50% of Internet traffic to a broadband service provider, depending on the usage patterns.
The contents of the caching engine are anonymous in nature and always depends on the user-requested content.
Following image depicts xCache implementation in a LAN.
xCache Server works in interactive mode. It analyzes traffic from port mirroring and identifies torrent traffic. It then does caching functionality and offers download to bittorrent clients on the lan side as a peer.
Hardware is a simple debian box with two ethernet interfaces with plenty of disk capacity and RAM. Typical installation has 3-5 2-TB hard disks on i3 machine with Debian 6 in 32-bit mode with 16 GB RAM.
Remote installation is done once you put hardware in place.
If you have a broadband network, there is no excuse for not having a caching engine that both saves on bandwidth cost and provides wire-speed downloads of torrent traffic to your subscribers.
