Abstract
A content distribution mechanism that relies on cooperative desktop PCs to distribute content is disclosed. The mechanism distributes content in a robust manner by allowing at least one intermediate network node (i.e., between a source and client) to generate and send packets that contain a linear combination of the portions of content available at the node. Such linear combinations may be created by the source and client using at least a portion of the original content file in either encoded or unencoded form. After the client has received enough linearly independent combinations of packets, the original content may be reconstructed.
