摘要： A wire protocol provides message formats for creating multiple network connections between a media server and a client. These multiple network connections may include a control link connection for passing control information and a data funnel connection for passing data of multiple media. The data funnel connection may be a multipoint-to-point connection that connects multiple data servers with the client. The protocol facilitates multiple requests being concurrently outstanding and asynchronous processing of requests. The protocol is designed to exist on top of a transport protocol layer.

摘要： An architecture and implementation for losslessly restarting subsystems in a distributed file system is described. By partitioning functionality and logging appropriately across the kernel and user-level boundaries on a client, the user-level subsystem may be made losslessly restartable. Practical mechanisms for supporting state-based recovery in replicated state machines and like replica are described. In particular, each client daemon may include an operations log and an applied log sequence number. Each client driver may include a potentially different operations log. Each client daemon may be configured to request logged operations associated with log sequence numbers in one or more ranges specified by a specification that includes the applied log sequence number. The requested logged operations may reside in the operations log maintained by a client driver. Each client daemon may operate in accordance with user-level constraints and each client driver may operate in accordance with kernel-level constraints.

摘要： Potentially identical objects (e.g., files) are located across multiple computers based on stochastic partitioning of workload. For each of a plurality of objects stored on a plurality of computers in a network, a portion of object information corresponding to the object is selected. The object information can be generated in a variety of manners (e.g., based on hashing the object, based on characteristics of the object, and so forth). Any of a variety of portions of the object information can be used (e.g., the least significant bits of the object information). A stochastic partitioning process is then used to identify which of the plurality of computers to communicate the object information to for identification of potentially identical objects on the plurality of computers.

摘要： A method and system for regulating tasks of background processes so as to reduce interference with foreground processes. The progress rate of a background task (e.g., amount of work performed per unit time) is measured and evaluated against a target amount. If the progress rate appears degraded, the background task is suspended for a computed time interval so as to back off from its interference with a foreground process. Each time the progress rate appears degraded, the time interval is exponentially increased from its previous value up to a maximum, however if the performance appears normal, the time interval is reset to a minimum. Evaluation of the work is statistically based so as to eliminate variations in measurements, and automatic calibration of the target amount is provided, as is a mechanism for prioritizing multiple background tasks.

摘要： A system includes protection against multiple senders in a multipoint to point data funnel that connects multiple data sources with a single data sink. The protection is afforded by employing tokens and by adopting a token protocol. In particular, a data source must be in possession of a token in order to send data on to a data funnel. The token exhibits that the data source has permission to output the data to the data funnel. The system may operate in the scheduled mode of operation where the system knows a priori when each data source will send data over the data funnel for a data sequence. The system may also operate in a nonscheduled mode where multiple data sources have data that they wish to send but the schedule of data transmissions from the data sources is not known a priori. The token protocol is adaptable to both scheduled mode and nonscheduled mode of operation. The token protocol also facilitates regeneration of tokens if tokens do not arrive at a destination that expects a token within a predetermined period of time.

摘要： A method and system is provided for tolerating component failure in a continuous media server system. The present invention guarantees data streams at a constant rate to subscribers for the data streams even when at least one component fails. The present invention is able to guarantee data streams at a constant rate by utilizing declustered mirroring and by reserving bandwidth for both normal mode processing and failure mode processing. The declustered mirroring of the present invention is performed by dividing the data to be stored in the continuous media server system into blocks. The blocks are then striped across the storage devices of the continuous media server system and each block is divided into a number of sub-blocks. The sub-blocks are in turn stored on separate storage devices. The present invention reserves bandwidth for both normal mode processing and failure mode processing. Since the present invention utilizes declustered mirroring, the bandwidth reserved for failure mode processing is reduced. Therefore, when a failure occurs, the bandwidth reserved for failure mode processing is utilized and the data streams to the subscribers are uninterrupted.

摘要： An operating provides a facility within its kernel for monitoring program performance. The facility may monitor user level programs as well as portions of the operating system, such as the kernel. The facility counts instructions and/or function calls to provide a useful performance metric to a user of the system. The count is forwarded to a user level monitoring program. The inclusion of the facility within the kernel enhances the speed of performance monitoring and enables the operating system to be directly monitored by the facility.

摘要： Embodiments are directed to processing read-only operations without storing the operations persistently, determining a processing order for read-only requests, and to directing read-only requests to nodes best able to handle the requests. In an embodiment, a quorum leader receives various read-only requests. The quorum leader controls process ordering for replicas in the leader's quorum. The quorum leader determines an appropriate order for processing the read-only operations, without clock-based synchronization. The quorum leader sends the read-only request to an appropriate replica in the quorum and executes the read-only request at the appropriate replica without storing the operation persistently.

摘要： Cryptographic protocols and methods of employing the same are described. The described protocols advantageously enable two or more identical encryptable objects that are coded for encryption with different keys to be identified as identical without access to either the unencrypted objects or the keys that are used in the encryption process. Additionally, the protocols enable two or more identical encryptable objects to be processed with different encryption keys, yet be stored in a manner so that the total required storage space is proportional to the space that is required to store a single encryptable object, plus a constant amount for each distinct encryption key. In various embodiments, the encryptable objects comprise files and the cryptographic protocols enable encrypted files to be used in connection with single instance store (SIS) systems.
