IceShare

From Wikipedia, the free encyclopedia

IceShare is an unfinished peercasting system for Ogg multimedia. It has been in the planning stages since early 2004 but holdups in the development of other Xiph.org Foundation technologies have prevented much visible progress.

[edit] How It Works

Each user who receives an IceShare stream will also upload the stream as well to help continue the network. This allows the broadcaster to only broadcast a stream once or twice, and allow the users to distribute it among themselves. This requires very little bandwidth from the broadcaster. IceShare intends to use BitTorrent's swarming design to make this work but expects a much smarter tracker to orchestrate the flow of data through the network.

Clients use the IceT protocol to connect to a Tracker and make a request for a file. This file must already be known by the client and is typically supplied to the client by a URL, such as icet://127.0.0.1/something.ogg.

The Tracker, knowing which other IceShare Clients have the file already, will direct the new Client to one or more of the other Clients for specific pieces of the file they've requested. The new Client verifies pieces of the stream with the Tracker as they are received and thereby informs the Tracker that they have that piece available for others.
