20130067539 | ACCESS CONTROL MANAGEMENT - The subject disclosure relates to authorization based on a determination of permissions that can be granted for an action(s) to be performed on a resource. The determination of the permission is based on a set of rules that represent a theory including a notion of trust that has been divided into different sized tables. The tables are utilized to evaluate two or more input claims and to facilitate a determination of whether access to at least one system resource is to be granted. The evaluation can include matching the two or more input claims to rows in the table, wherein access is allowed if a match is found. | 03-14-2013 |
20130282789 | BINDING CRUD-TYPE PROTOCOLS IN DISTRIBUTED AGREEMENT PROTOCOLS - Various embodiments enable redundant or replica services, such as “cloud” services, to be run at geographically distributed locations. Each replica is capable of performing operations that are generally, identically performed across all replicas. In the event of an interruption at one location, services in other locations can quickly and automatically take over operations. In one or more embodiments, a Distributed Agreement Protocol is utilized to bind a CRUD-type protocol as a state machine. Binding takes place through the use of a reverse proxy that is located at each of the locations at which the service is distributed. In at least some embodiments, the Distributed Agreement Protocol is implemented as the Paxos protocol or a variant thereof, and/or the CRUD-type protocol comprises the HTTP protocol. | 10-24-2013 |
