Method and apparatus for a fault resilient collaborative media serving array

摘要

Embodiments of the present invention provide methods, systems, and apparatuses for a fault resilient collaborative media serving array comprising a plurality of nodes. In one embodiment, the present invention provides a method for creating a fault resilient collaborative media serving array where the array nodes do not share memory, the serving of a content file is accomplished by the collaborative efforts of many nodes in the array, and where there is no fixed allocation of sessions to nodes.

1. A method for recovering from fault in a content serving array comprising at least a first node, a second node, and a third node, the method comprising:
partitioning content into an ordered list of parts comprising at least a first part and a second part; allocating the first part to the first node; allocating the second part to the second node; sending the content successively and chronologically in-order as an ordered stream of parts corresponding to the ordered list by:
indicating to the first node that it should send the first part to a client device;failing to receive by the second node an indication that the first node has sent the first part to the client device;indicating to the third node that it should send the first part to the client device;sending by the third node the first part to the client device; andsending by the second node the second part to the client device.
