摘要： Disclosed are a connectivity platform that allows for proprietary connectivity modules to plug into the operating system and also allows the operating system users and various existing networking applications in the operating system that are authorized by those providers to use that connectivity via existing APIs without the need for the applications to change or for extra configuration of the application to be performed. In an example disclosed herein, the providers provide NAT or firewall traversal and implement the appropriate transport mechanism. This allows for applications and computing devices to communicate in environments where connectivity is prevented by intermediate systems.

摘要： Methods and computer program products are disclosed for providing QoS for Web applications via an internet service application programming interface “ISAPI”) filter running on an internet information server, wherein the ISAPI filter uses a traffic control application programming interface to manage bandwidth for individual HTTP requests. Responses to HTTP requests can be prioritized based on policies defined by the Web application developer, wherein policy decisions may be made based on many different parameters, such as, for example, the IP address of the Web browser making the request, the type of browser being used, HTTP “cookies,” the uniform resource locator being requested, an authenticated user ID, or any other information that is exposed from the internet information server through server variables. The present invention accomplishes this with no modifications to the internet information server, and •with very minimal changes to the Web application.

摘要： A technique coherently suspends input/output (I/O) operations in a RAID subsystem of a storage system. A configuration tree of the RAID subsystem has a plurality of objects representing a logical configuration of storage devices coupled to the system. According to the technique, a “freeze” condition may be imposed on an object of the configuration tree to suspend I/O operations directed to that object. In order to freeze, I/O operations underway (“in flight”) in the RAID subsystem and directed to the object need to complete sufficiently so as to reach a recoverable state in the event the subsystem subsequently fails prior to an I/O restart procedure. Once a freeze condition has been imposed, new I/O requests directed to the object are inserted onto a freeze list of pending requests at the RAID subsystem and are blocked from processing until the object is “unfrozen” (i.e., the freeze condition is lifted).

摘要： An access control mechanism in a network connecting one or more sink devices to a server providing audio/visual data (A/V) in streams. As a sink device requests access, the server measures available bandwidth to the sink device. If the measurement of available bandwidth is completed before the sink device requests a stream of audio/visual data, the measured available bandwidth is used to set transmission parameters of the data stream in accordance with a Quality of Service (QoS) policy. If the measurement is not completed when the data stream is requested, the data stream is nonetheless transmitted. In this scenario, the data stream may be transmitted using parameters computed using a cached measurement of the available bandwidth to the sink device. If no cached measurement is available, the data stream is transmitted with a low priority until a measurement can be made. Once the measurement is available, the transmission parameters of the data stream are re-set. With this access control mechanism, A/V streams may be provided with low latency but with transmission parameters accurately set in accordance with the QoS policy.

摘要： The invention provides quality-of-service (QoS) delivery services over a computer bus having isochronous data transfer capabilities. A transmitting node on the bus transmits a message to an intended recipient indicating a requested bandwidth for a connection. If the intended recipient has sufficient resources, it allocates an isochronous data channel on the bus and notifies the transmitter of the allocated channel. Thereafter, the transmitter transmits the data on the allocated channel. If the recipient cannot allocate a channel, it does not respond, and the transmitter thereafter detects a time-out condition and begins transmitting using a “best efforts” scheme (i.e., non-guaranteed time delivery). In a second variation, a receiving node detects that it is receiving large quantities of data from a transmitting node. In response, the receiving node allocates an isochronous data channel on the bus and notifies the transmitter of the allocated channel. Thereafter, the transmitter transmits using the allocated isochronous channel. In a third variation, multiple receiving nodes that need to receive streaming data from a single transmitting node share a common isochronous data channel. In any of these variations, each receiver can periodically transmit a “deadman” timer message on a broadcast channel to indicate that it is still receiving on a given channel. If a transmitter detects that the deadman timer has expired, it reverts to transmitting data using a “best-efforts” scheme. A transmitter can transmit both to receivers that can handle QoS services and those that cannot explicitly support QoS services.

摘要： A method and apparatus for a reliable data storage system using block level checksums appended to data blocks. Files are stored on hard disks in storage blocks, including data blocks and block-appended checksums. The block-appended checksum includes a checksum of the data block, a VBN, a DBN, and an embedded checksum for checking the integrity of the block-appended checksum itself. A file system includes file blocks with associated block-appended checksum to the data blocks. The file blocks with block-appended checksums are written to storage blocks. In a preferred embodiment a collection of disk drives are formatted with 520 bytes of data per sector. For each 4,096-byte file block, a corresponding 64-byte block-appended checksum is appended to the file block with the first 7 sectors including most of the file block data while the 8th sector includes the remaining file block data and the 64-byte block-appended checksum.
