Abstract
The present disclosure provides methods and systems for multicast collaborative erasure encoding and methods and systems for distributed parity protection. One embodiment relates to a method of multicast collaborative erasure encoding of a chunk stored in a distributed object storage cluster. A roll-call request is multicast to every storage server in a negotiating group for the chunk. Roll-call inventory responses are generated and multicast by every storage server in the negotiating group. The roll-call inventory responses are collected by every storage server in the negotiating group from other storage servers in the negotiating group to form a set of roll-call inventory responses. A logical evaluation of the set of roll-call inventory responses may then be performed by every storage server in the negotiating group. Other embodiments, aspects and features are also disclosed.
