Abstract: A read-disturb-based read temperature time-based attenuation system includes a storage device that is coupled to a global read temperature identification subsystem. The storage device determines current read disturb information for data stored in a block in the storage device during a current time period, processes the current read disturb information and previous read disturb information that was determined during at least one previous time period that was prior to the current time period in order to generate a read temperature for the data stored in the block, generates a local logical storage element read temperature map that includes the read temperature, and provides the local logical storage element map to the global read temperature identification subsystem.

Abstract: A read disturb information isolation system includes a storage subsystem including a plurality of blocks that each include a plurality of rows, and a read disturb information isolation subsystem that is coupled to the storage system. For at least one of the plurality of blocks, the read disturb information isolation system retrieves data from at least a subset of rows in that block, identifies read disturb information for that data, performs at least one isolation operation on that read disturb information to generate isolated read disturb information, and provides that isolated read disturb information to a read temperature identification subsystem. The read temperature identification subsystem may then use the isolated read disturb information provided by the read disturb information isolation subsystem to generate a local logical storage element read temperature map.

Abstract: A read-disturb-based read temperature determination system includes a storage device that is coupled to a read temperature adjustment subsystem. The storage device receives data from the read temperature adjustment subsystem, stores the data in a block in the storage device, identifies read disturb information for a row in the block at a plurality of different times, processes the read disturb information to generate a read temperature for the row, provides the read temperature in a local logical storage element read temperature map and, based on instructions from the read temperature adjustment subsystem, adjusts the read temperature provided in the local logical storage element read temperature map.

Abstract: A read disturb information determination system includes a storage device coupled to a global read temperature identification system. The storage device reads, from a first row in a storage subsystem in the storage device, data stored in bits that were previously identified as being susceptible to read disturb effects, and error correction information associated with the data. The storage device uses the error correction information to identify a number of the bits that store portions of the data with errors and, based on the number of bits that store portions of the data with errors, determines read disturb information for the first row in the storage subsystem in the storage device. The storage device then uses the read disturb information to generate a read temperature for a second row in the storage subsystem in the storage device, and provides the read temperature to the global read temperature identification system.

Abstract: A read-disturb-based read temperature information persistence system includes a storage device coupled to a host subsystem. The storage device receives a first instruction from the host subsystem to write first data to the storage device, writes the first data to a first block in the storage device, and determines first read temperature(s) for the first data based on first read disturb information associated with the first block in the storage device. When a second instruction is received from the host subsystem to write second data to the storage device that is an updated version of the first data, the storage device identifies the first read temperature(s) determined for the first data in the first block in the storage device, and writes the second data and a first read temperature indication of the at least one first read temperature to a second block in the storage device.

Abstract: A read-disturb-based read temperature adjustment system includes a read temperature adjustment subsystem that is coupled to the storage device. The read temperature adjustment subsystem identifies data that is stored in a block in the storage device and that is associated with a read temperature that is based on read disturb information associated with the block, determines a read temperature adjustment level for the data based on one or more data characteristics of the data and, based on the read temperature adjustment level, transmits a read temperature adjustment instruction to the storage device that causes the storage device to adjust the read temperature associated with the data.

Abstract: A storage device read-disturb-based block read temperature utilization system includes a storage device chassis housing a storage subsystem. A local read temperature utilization subsystem in the storage device chassis determines that data in a first block in the storage subsystem should be moved and, in response determines read disturb information for the first block and uses it to identify relative read temperatures for a plurality of rows in the first block in the storage subsystem. The local read temperature utilization system then moves the data from the first block in the storage subsystem to at least one second block in the storage subsystem based on the relative read temperatures identified for the plurality of rows in the first block in the storage subsystem.

Abstract: A read-disturb-based logical storage read temperature information maintenance system includes a global read temperature identification subsystem coupled to storage device(s). Each storage device identifies, from a physical block in that storage device, current read disturb information associated with a row provided by the physical block in that storage device, and maps the current read disturb information to logical storage element(s) included in a logical-to-physical storage element mapping for that storage device along with previous read disturb information that was previously mapped to those logical storage element(s) included in the logical-to-physical storage element mapping for that storage device.

Abstract: A storage device read-disturb-based read temperature map utilization system includes a storage device chassis housing a storage subsystem. A local read temperature utilization subsystem in the storage device chassis determines read disturb information for a plurality of blocks in the storage subsystem, uses it to identify a subset of rows in block(s) in the storage subsystem that have a relatively higher read temperature and, based on those read temperature identifications, generates a local logical storage element read temperature map that identifies a subset of logical storage elements associated with the storage subsystem that have a relatively higher read temperature. The local read temperature utilization subsystem then moves data from first block(s) in the storage subsystem to second block(s) in the storage subsystem based on relative read temperatures identified in the local logical storage element read temperature map.

Abstract: A system and method for providing an apparent echo return loss is provided. A communications network may include a gateway coupled to a local exchange network. The gateway may receive signals from a packet network and output signals to a circuit switched network, which may output return signals to the gateway. The local exchange network may provide an echo return loss on signals received from the gateway. The gateway may also provide an initial echo return loss to signals prior to sending the signals to the network. The echo return loss provided by both the gateway and the local exchange network may enable the gateway to determine when to trigger adaptation in order to provide estimates of echo signals generated by the network, and to subsequently eliminate these echo signals from the return signals.

Abstract: A system and method for receiving a transported stream of data packets at a network includes stripping the headers off the data packets at a de-packetizer, buffering the data packets at a jitter buffer and shifting the play-out of the data packets from the jitter buffer to a decoder by at least a fraction of a frame to provide a desired value of channel jitter compensation. The shift in the play-out of the data packets is computed either using a watermark optimization calculation, a frame phase offset adjustment which reduces the delay between packet arrival times and packet depletion times, or a combination of the two.

Abstract: A method and apparatus for distributing protocol processing among a plurality of computing platforms. Data communications equipment such as Remote Access Devices, Communication Servers, Terminal Servers, and Dial-up Routers provide single user or large-scale multiple user communication access to various computing environments. The equipment costs and performance of such access equipment is related to the amount of CPU processing capability and memory required to support the desired number of serial communication links. It is common to use protocols that terminate in their entirely in the same processing machine. This invention encompasses methods developed to increase the cost/performance capabilities of the communication equipment that supports these serial links, primarily by means of distributing the protocol processing for higher level protocols across multiple computing platforms, including devices such as modems. Examples of such higher level protocols include PPP, SLIP and RTP.
