A system and method for automating the web service selection based on reputation information, to help negotiate a contractual web service binding between a client and a server. Reputation information may be schematized into behavioral attributes such as web service responsiveness, web service latency, web service uptime, cost data, business solvency and other trustworthiness and business-related data. Some of the reputation data may be empirically determined, and provided by an independent or other trusted auditor. In one implementation, a client queries a search engine, which returns a ranked list of web services, with the ranking based on reputation scores computed for each web service as collected by an auditor. Clients may provide computational data to weigh the attributes separately. A corporate internet can maintain reputation data for web services to act as an auditor, and a web service server can also execute trusted code to act as an auditor.

A data chunking system divides data into predominantly fixed-sized chunks such that duplicate data may be identified. The data chunking system may be used to reduce the data storage and save network bandwidth by allowing storage or transmission of primarily unique data chunks. The system may also be used to increase reliability in data storage and network transmission, by allowing an error affecting a data chunk to be repaired with an identified duplicate chunk. The data chunking system chunks data by selecting a chunk of fixed size, then moving a window along the data until a match to existing data is found. As the window moves across the data, unique chunks predominantly of fixed size are formed in the data passed over. Several embodiments provide alternate methods of determining whether a selected chunk matches existing data and methods by which the window is moved through the data. To locate duplicate data, the data chunking system remembers data by computing a mathematical function of a data chunk and inserting the computed value into a hash table.

A method dramatically reduces the amount of data to be stored and transferred in a networked storage system. Preferably, the network storage system provides continued data protection through mirroring / replication, disk-to-disk backup, data archiving for future retrieval, and Information Lifecycle management (ILM). The idea is to leverage the parity computation that exists in RAID systems. By caching, transferring, and storing data parity or delta bytes of changes on a block as opposed to data block itself, substantial data reduction is possible without using sophisticated compression algorithms at the production side to minimize performance impacts upon production servers. Data can be computed using the parity / delta and previously existing data at mirror side, replication side, backup storage, or at retrieval time upon events such as failures or ILM operations.

A method and mechanism for generating object signatures within a file system. A file system is configured to generate signatures for objects such as files. The file system periodically scans objects to identify those which require computation of a new signature. Upon identifying such an object, the file system divides the object into partitions. A transient signature value is then generated for each partition of the object and stored. Upon a subsequent access to the object, a determination may be made as to whether or not a valid signature exists for the object. If a valid signature does not exist for the object, a new signature may be generated for the object by using one or more previously stored valid transient signature values which correspond to particular partitions of the object. The transient signature values which are used may serve as a seed for computation of those transient signature values for object partitions which follow the particular partition. Both object signatures and transient signature values may be cached by the file system and returned in response to requests from user space processes.
