Abstract: An IP Storage processor and processing engines for use in the IP storage processor is disclosed. The IP Storage processor uses an architecture that may provide capabilities to transport and process Internet Protocol (IP) packets from Layer 2 through transport protocol layer and may also perform packet inspection through Layer 7.

A scheduler schedules packets to packet processors for processing. An internal memory or local session database cache may store a transport protocol session information database and/or store a storage information session database, for a certain number of active sessions. The session information that is not in the internal memory is stored and retrieved to/from an additional memory.

Abstract: One embodiment of the invention relates to the transfer of content between a host computer that issues OAS access requests and a block I/O storage system. Specifically, a host computer may issue an access request for a content unit that identifies the content unit is an object identifier. The request may be received by a second server, which may determine the block address(es) on the block I/O storage system at which the content unit is stored. A request may then be sent to the block I/O storage system to retrieve the content stored at the requested block address(es) and the block I/O storage system may return the content.

Abstract: A computer network system includes a client-server architecture, where the client transmits SCSI commands over a network using TCP/IP to a server to request input and output operations for a physical storage device that is communicatively coupled to a storage device. The client perceives the storage device to be a local disk drive, even though the storage device is located on the target side of a network. The system includes a client-side disk-based cache.

Abstract: The invention is directed to techniques for managing access to data available from a data access device using a network switching protocol to manage content requests from clients. A data communications device receives a request for content from a client. The data communications device, such as a network switch, exchanges signals using the network switching protocol with one or more data access devices, such as a web cache. The data communications device can then select one data access device to provide the requested content to the client based, for example, on load balancing considerations. The data communications device sends a data transfer approval signal to the selected data access device. The selected data access device establishes a connection with the client using information, such as the client's network address, provided by the signals. The selected data access device then bypasses the data communications device and sends the requested content to the client.

Abstract: Provided are a method of providing a service relating to content stored in a portable storage device to an external device, and an apparatus therefor. The method includes outputting a user interface to manage information relating to contents stored in the portable storage device through a display unit associated with the external device, receiving a command to select content from among the contents through the output user interface, executing a service corresponding to the content selected based on the command, and providing a result of executing the service to the external device.

Abstract: A Multi-Homing System is equipped with an Adaptive ISP Access Cloud State Detection apparatus (ACSD) that improves the reliability of the availability of digital connections (links) between computer sites, such as a Computer Premises Network and the Internet, in which such connections are made by connecting through a multiplicity of ISP Access Clouds (links). Reliability is improved over prior art methods by using data elements of Internet Protocol datagrams, e.g. record fields or bits of fields, that are regularly and normally exchanged between the ISP Access Clouds and the CPN without creating additional data traffic. Data Elements from each ISP Access Cloud are used by processing functions of the by the ACSD to test for conditions that indicate that it may be in a DOWN status.

Abstract: Systems and methods for performing native command queuing according to the protocol specified by Serial ATA II for transferring data between a disk and system memory are described. Native command queuing context for queued commands is maintained by a host controller device driver and is provided to the host controller as needed to process the queued commands. The host controller is simplified since it only stores the context of the one command being processed. The host controller generates a backoff interrupt when a command cannot be queued. The host controller generates a DMA transfer context request interrupt to request programming of the registers that store the context for the one command being processed.

Abstract: A system and method for reducing call establishment delay in wireless network is provided, in which a network node establishes a call to a wireless terminal controlled by an AP via a server. The wireless terminal notifies the server of its listen interval. In the power saving mode, the wireless terminal wakes up every listen interval and listen the beacon to check whether any buffered packet for it. When the wireless terminal learns from the beacon that there are packets waiting, it communicates with the access point to retrieve them. The server records a listen time at which the wireless terminal will wake up and listen to the AP based on the listen interval. When a network node calls the wireless terminal, the server buffers the request for a time interval based on the listen time, and then sends the request to the wireless terminal.

Abstract: A remote DMA (RDMA) shim protocol laid atop an existing network data transfer protocol but logically underneath higher level disk and file access protocols specifies the portion of a data packet to be transferred directly into a separate area of memory such as an application layer memory buffer. This RDMA protocol identifies the area of memory into which the data should be delivered, a data ID, data start, data length or end, and flag bits. Option fields added to (or already present in) the transport protocol describe the RDMA transfer. On reception of a packet specifying RDMA, the receiving device delivers the data directly into the correct memory location using the RDMA description data. In some embodiments of the present invention, the RDMA shim protocol is implemented with TCP options specifically introduced to enable RDMA and thus reduce the overhead of transferring and receiving data with a TCP-based protocol such as NFS or HTTP.

Abstract: A system for sharing block data includes a non-removable device for storing block data (e.g. a hard drive) that is networked with a plurality of computers. Each computer can initiate discovery commands and read/write commands, and transmit these commands over the network to the non-removable storage device. Computer commands are intercepted and processed by a logical algorithm program at the storage device. One function of the logical algorithm program is to instruct each computer to treat the non-removable block storage device as a removable block device. Because the computers treat the storage device as a removable block device, they relinquish control of the device (after use) to other computers on the network. The logical algorithm program also functions to allocate temporary ownership of the block storage device to one of the computers on the network and passes temporary ownership from computer to computer on the network.

Such a step eliminated the need for a separate transmission of the write control information. The CDB is transmitted along with a data block from the primary storage controller to the secondary storage controller and placed in the respective, pre-allocated buffers. Data may also be pipelined to the secondary.

Abstract: A method of providing a fast path message transfer agent is provided. The method includes receiving bytes of a message over a network connection and determining whether the number of bytes exceeds a predetermined threshold. If the number of bytes is less than a predetermined threshold, then the message is written only to memory. However, if the number of bytes exceeds the predetermined threshold, then some of the bytes (e.g. up to the predetermined threshold) are written to memory, wherein the remainder of the bytes are stored onto the non-volatile storage. If the message was received successfully by each destination, then the message is removed from the memory/non-volatile storage. If not, all failed destinations are identified and the message (with associated failed destinations) is stored on the non-volatile storage for later sending.
