摘要： A method for data communication between a first node and a second node includes forming one or more redundancy messages from data messages at the first node using an error correcting code and transmitting first messages from the first node to the second node over a data path, the transmitted first messages including the data messages and the one or more redundancy messages. Second messages are received at the first node from the second node, which are indicative of: (i) a rate of arrival at the second node of the first messages, and (ii) successful and unsuccessful delivery of the first messages. A transmission rate limit and a window size are maintained according to the received second messages. Transmission of additional messages from the first node to the second node is limited according to the maintained transmission rate limit and window size.

摘要： A channel encoding method in a communication or broadcasting system is provided. The channel encoding method includes reading a first sequence corresponding to a parity check matrix, converting the first sequence to a second sequence by applying a certain rule to a block size corresponding to a parity check matrix and the first sequence, and encoding information bits based on the second sequence. The block size has at least two different integer values.

摘要： Memory controllers, devices and associated methods are disclosed. In one embodiment, a memory controller includes write circuitry to transmit write data to a memory device, the write circuitry includes a write error detection correction (EDC) encoder to generate first error information associated with the write data. Data bus inversion (DBI) circuitry conditionally inverts data bits associated with each of the write data words based on threshold criteria. Read circuitry receives read data from the memory device. The read circuitry includes a read EDC encoder to generate second error information associated with the received read data. Logic evaluates the first and second error information and conditionally reverse-inverts at least a portion of the read data based on the decoding.

摘要： A method includes identifying, by a dispersed storage (DS) processing unit of a plurality of DS processing units of a dispersed storage network (DSN), a DSN operation to be performed that will adversely interfere with processing of DSN access requests. The method further includes sending, by the DS processing unit, a suspension request to a process balancing module of the DSN where the suspension request is for temporarily suspending processing of DSN access requests. The method further includes determining, by the process balancing module, whether sufficient processing resources of active DS processing units of the plurality of DS processing units are available for processing DSN access requests on behalf of the DS processing unit. When determined that sufficient processing resources are available, the method further includes granting the suspension request, and allocating DSN access requests of the DS processing unit to one ore of the active DS processing units.

摘要： Disclosed herein are embodiment that are directed to a method comprising storing each encrypted data block, of a cyphertext page, with corresponding encrypted error correction code (ECC) bits in a persistent memory device (PMD). In exemplified embodiments, the encrypted ECC bits verify both an encryption counter value of an encryption operation and a plaintext block of the cyphertext page from a decryption operation. In other embodiments, the method includes decrypting, using the decryption operation during a read operation of a memory controller, a respective one block of the cyphertext file and the corresponding encrypted ECC bits stored in the PMD using a current counter value to form the plaintext block and decrypted ECC bits. Further, the may include verifying the plaintext block with the decrypted ECC bits; and performing a security check of the encryption counter value in response to the plaintext block failing the verification, using the decrypted ECC bits. A system and secure processor that are configured to perform the disclosed methods are provided.

The method continues with the first group of computing devices interpreting the data objects having the first data type identifier to sort, based on sorting criteria the data objects into a first processing category and a second processing category. The method continues with the first group of computing devices error encoding the data objects in the second processing category based on short term storage error encoding parameters to produce pluralities of sets of encoded data slices and sending the pluralities of sets of encoded data slices to storage and execution units for storage therein.

摘要： A method includes detecting, by a vault management device, a failed storage unit common to a first vault and a second vault. The first vault is associated with a first set of storage units and the second vault is associated with a second set of storage units. The failed storage unit is in each of the first and second sets of storage units. The method further includes identifying a number of non-failed storage units of the first and second sets of storage units and comparing the number of non-failed storage units with first and second decode threshold numbers to determine a failure impact level. The first decode threshold number is associated with the first vault and the second decode threshold number is associated with the second vault. The method further includes determining a failure abatement approach based on the failure impact level and facilitating the failure abatement approach.
