MULTI-PROTOCOL LOCK MANAGER FOR DISTRIBUTED LOCK MANAGEMENT

Abstract:

Techniques are provided for distributed lock and authorities management. An origin may host a resource, such as a file, that may be accessed by clients through a plurality of caches. The origin may receive a first retrieve request from a first endpoint to obtain a first authority for a resource. The origin may delegate the first authority for the resource to the first endpoint. The origin may delegate the second authority for the resource to the second endpoint in response to determining that the delegated authority information and a set of locks held by the origin do not conflict with a second retrieve request from a second endpoint to obtain a second authority.
