Title: CONTENT DISTRIBUTION SYSTEM AND METHOD
Abstract:
There are described methods and systems for distributing content in a network, in particular a multicast network. One method includes delivering content from a source to a destination in a content delivery network. A request for an item of content is received and a first multicast stream is identified or established, the first multicast stream comprising a first copy of the content. At least one second multicast stream is also identified or established, the second stream comprising a second copy of the content. The second copy of the content is time-shifted by a time, M, from corresponding portions of the first copy of the content. The content is then delivered to the destination using both the first and the second multicast streams.
