System and method for identifying data corruption in a data transfer over an error-proof communication link, wherein additional structure checksums are formed to secure a data structure during transfer of the data structure, where representatives are associated with the data types, and the structure checksum is formed via the representatives to provide identification of data corruption in a data transfer over an error-proof communication link between a first automation component and a second automation component in industrial control engineering.

The ability to accurately and efficiently calculate and report communication errors is becoming more important than ever in today's communications environment. More specifically calculating and reporting CRC anomalies in a consistent manner across a plurality of communications connections in a network is crucial to accurate error reporting. Through a normalization technique applied to a CRC computation period (e.g., the PERp value), accurate error identification and reporting for each individual connection can be achieved.

Some embodiments of the invention provide a forwarding element that can be configured through in-band data-plane messages from a remote controller that is a physically separate machine from the forwarding element. The forwarding element of some embodiments has data plane circuits that include several configurable message-processing stages, several storage queues, and a data-plane configurator. A set of one or more message-processing stages of the data plane are configured (1) to process configuration messages received by the data plane from the remote controller and (2) to store the configuration messages in a set of one or more storage queues. The data-plane configurator receives the configuration messages stored in the set of storage queues and configures one or more of the configurable message-processing stages based on configuration data in the configuration messages.

A highly resilient, scalable, high-performance data storage system that stripes its content across peer computers in a data cluster, across data clusters in a cluster group, and across cluster groups in a multi-cluster-group Hyper Storage System. Multiple peers can fail within a data cluster, even beyond the FEC level configured in the cluster, without disrupting the clients. Multiple entire data clusters can fail or be taken out of service without disrupting the clients. Peer failures are detected by the cluster and all missing data is seamlessly regenerated through vertical and/or horizontal resiliency so the great majority of I/O operations complete successfully.

A touch data transmission method of present disclosure includes: generating a header information by a first controller according to a detected touch event; generating a first checksum information by the first controller according to the header information; storing the header information and the first checksum information to a memory by the first controller; and, storing a plurality of position information of the detected touch event to the memory by the first controller.

An accessory and an electronic device enabling retransmission of data from the electronic device to the accessory when a checksum error occurs in the accessory. An accessory controller of the accessory determines whether or not a checksum received from the camera and a first checksum calculated from data received from the camera match. In a case where the checksums match, the accessory controller calculates a second checksum, whereas in a case where the checksums do not match, the accessory controller calculates a third checksum. The accessory controller transmits the second checksum or the third checksum to the camera according to a result of the determination.

In the repeated transmission of information in the form of a coded packet from a transmitter via a radio link to a receiver, an interference-free receive packet is quickly available if interference-free subpackets are assembled from the packet as subpackets of the interference-free receive packet. For this purpose, subpackets of successively received and temporarily stored packets assigned to one another can be compared with one another and, in the event of a match, can be inserted in a gap-filling manner into the received packet. Alternatively, the successive packets are already divided in each case at the transmitting end into subpackets provided with error detection codes, the subpackets being incorporated into the received packet as soon as they have been correctly received in a packet.

This invention discloses a network data prediction method, a network data processing device, and a network data processing method. The network data processing method is applied to a device that implements an open systems interconnection model (OSI model) and includes the following steps: generating a first data block and a second data block according to the OSI model; processing the first data block based on an error detection method to generate a first check code; encoding the first data block and the first check code to generate a first network data; transmitting the first network data; and receiving a second network data that includes a second check code; generating a target data according to a portion of the second data block and a portion of the second network data; and checking the target data according to the second check code.

In one embodiment, the present invention includes a method for receiving incoming data in a processor and performing a checksum operation on the incoming data in the processor pursuant to a user-level instruction for the checksum operation. For example, a cyclic redundancy checksum may be computed in the processor itself responsive to the user-level instruction. Other embodiments are described and claimed.

A device includes a processor and a checksum module, wherein the checksum module calculates, for first data, an updated checksum that complies with Internet Engineering Task Force Request For Comments Number 1624 using twos-complement arithmetic. The processor replaces the original checksum with the updated checksum to update a data packet.
