Patent number: 7814499Abstract: A system and method for expediting the replication of at least one specified object to a replica in a distributed computer system. A source object of a source replica determines that it has an urgent change to propagate through the distributed system, and informs a replication facility at the source replica of the urgent change. The facility extracts, or is provided with, the change information from that object, and the source replica communicates information representative of the change to a destination replica. A replication facility at the destination replica provides the change information to a destination replica object, which uses the information to make itself consistent with the source replica object.Type: GrantFiled: December 12, 2005Date of Patent: October 12, 2010Assignee: Microsoft CorporationInventors: Dave D. Straube, Aaron M. Contorer, Arnold S. Miller, Balan S. Raman, Pradyumna K. Misra, Michael R. C. Seaman

Patent number: 6457053Abstract: A system for multi-master unique identifier allocation comprises a server for allocating pools of identifiers to requesting servers and at least one server for requesting pools of identifiers and allocating individual identifiers as necessary. A single master server allocates “pools” of unique identifiers to network servers upon request. The network servers in turn allocate unique identifiers from their pool as necessary when the server generates new system objects. When a network server's pool of unique identifiers is nearly depleted, the network server requests an additional pool of identifiers from the master server.Type: GrantFiled: September 21, 1998Date of Patent: September 24, 2002Assignee: Microsoft CorporationInventors: Murli D.

Patent number: 6049809Abstract: A system and method of efficiently replicating data structures in a distributed system of replicas. Each replica in the distributed system maintains a cursor indicative of the extent to which other replicas in the system are consistent with one another. By examining the information in its cursor, a destination replica requesting replication from a source replica is able to determine the extent to which it has been made consistent with that source replica via indirect paths, thus potentially improving the starting point of replication. The source replica similarly examines its cursor to potentially improve the starting point of replication with respect to the starting point requested by the destination replica. In this manner, redundant information transmitted from a source replica when replicating a destination replica is reduced.Type: GrantFiled: October 30, 1996Date of Patent: April 11, 2000Assignee: Microsoft CorporationInventors: Balan S. Raman, Arnold S. Miller, Dave D. Straube, Shioupyn Shen

Patent number: 5968121Abstract: A network directory and naming service include fields for identifying instances of network resources and other objects by both logical and topological grouping. This combination of information facilitates automated efficient decision making with regard to replication of resources and updating the replicas in response to changes. The combination of logical and topological identification for resources also facilitates selection of a close replica in instances where a client requests access to a resource, such as a server, for which communicatively local and remote instances exist.Type: GrantFiled: August 13, 1997Date of Patent: October 19, 1999Assignee: Microsoft CorporationInventors: Keith W. Logan, Pradyumna K. Misra, Paul J. Leach, Clifford P. Van Dyke, Dave D. Straube, Arnold S. Miller
