DATA TRANSFER WITH MULTIPLE THRESHOLD ACTIONS
One example may include transmitting data between a client device and a server over a first channel, sending test data on a second channel to identify a transmission rate of the second channel, comparing the transmission rate to a transmission rate threshold, and determining whether to perform bonding of the first channel with the second channel based on the transmission rate of the second channel being greater or less than the transmission rate threshold.
Soft FEC with parity check
A data transmission device includes a de-interleaver configured to receive, from a host device at a first data rate, a data stream including encoded data, de-interleave the data stream into a plurality of forward error correction (FEC) data streams, and output the plurality of FEC data streams at a second data rate less than the first data rate. Each of a plurality of interleavers is configured to interleave a respective one of the plurality of FEC data streams into an intermediate data stream including first data blocks and second data blocks. An encoder module configured to generate, for each of the intermediate data streams, FEC blocks including a first parity section and a first data section, the first parity section including a first parity bit corresponding to the first data blocks and a second parity bit corresponding to the second data blocks, and the first data section including the first data blocks and the second data blocks, and output the FEC blocks at the second data rate.
Enhanced error protection of payload using double CRC
A method for enhanced error protection using double-cyclic redundancy check (CRC) includes receiving a first packet, by a first physical layer (PHY). The first packet includes a source packet and a first CRC. The method also includes encrypting the first packet having the first CRC to generate an encrypted first packet. The method further includes appending a second CRC to the encrypted first packet to produce a second packet, and transmitting the second packet to a second PHY via a transmission line.
Simultaneous acknowledgments for multicast packets
In one embodiment, a multicast communication is received at a particular node of a plurality of nodes receiving the multicast communication in a network. The particular node selects a subset of subcarriers using a probabilistic data structure, such that each of the plurality of nodes selects a respective subset of subcarriers using the probabilistic data structure. The particular node transmits an acknowledgement of receipt of the multicast communication on the subset of subcarriers selected by the particular node. The transmission occurs simultaneously with transmissions of acknowledgements from the other of the plurality of nodes.
Soft FEC with parity check
The present invention is directed to data communication systems and techniques thereof. More specifically, embodiments of the present invention provide an FEC encoder that processes an interleaved data stream and generates parity symbols that are embedded into FEC blocks. An FEC decoder determines whether to perform error correction based on the parity symbols. When performing error correction, the decoder selects a worst symbol from a segment of symbols, and the worst symbol is corrected. There are other embodiments as well.
COMMUNICATION APPARATUS AND COMMUNICATION METHOD, AND PROGRAM
The present disclosure relates to a communication apparatus and a communication method, and a program which make it possible to achieve higher reliability.
When a packet is distributed to a plurality of lanes and transmitted, at least one of a packet header or a packet footer of the packet is transmitted independently in each of the lanes. The packet footer transmitted in each of the lanes is CRC calculated from a payload of the packet distributed to each of the lanes corresponding thereto, and the packet header transmitted in each of the lanes includes word count indicating the number of bytes of a payload of the packet distributed to each of the lanes corresponding thereto. The present technology can be applied to, for example, a communication system used for connecting an on-board camera.
Cognitive use of multiple regulatory domains
A wireless communication system that concurrently communicates information in multiple regulatory domains to facilitate audio/video media streaming and other high bandwidth operations. One domain may be licensed and the other may be unlicensed. Transmission in the licensed domain may occur in white space in the domain, and the amount of information transmitted in that domain may be limited by regulations. The amount of information conveyed in the licensed domain may also depend on channel conditions in either or both of the domains. As a result, the relative amount of information transmitted in each domain may vary dynamically. The system includes a transmitter that dynamically determines weighting coefficients applied to each of a plurality of channels to set power levels in both domains to achieve a desired metric for the overall communication. A corresponding receiver assembles the substreams into a stream that can then be displayed or otherwise processed.
END-TO-END NEGATIVE ACKNOWLEDGMENT
A processing device includes a transceiver to be coupled to a link and control logic coupled to the transceiver. The control logic is to assign a unique sequence identifier to each packet to be transmitted across the link to a receiving node and transmit packets via the transceiver across the link to the receiving node. Each packet is to have a unique sequence identifier. The control logic also is to receive a message from the receiving node, the message containing the sequence identifier of a packet not correctly received by the receiving node. Based on the received message, the control logic is to cause an end-to-end negative acknowledgment (E2E NAK) packet to be transmitted to an originating node of the packet that was not correctly received.
Radio channel utilization
The concepts relate to radio channel utilization. One example can channel bond a first available channel from a first radio frequency band with a second available channel from a second radio frequency band. The example can transmit a portion of a forward error correction coded data stream over the first available channel and a different portion of the forward error correction coded data stream over the second available channel.
System and method for optimizing link performance with lanes operating at different speeds
A serial communication link includes a receiver and a transmitter coupled to the receiver by a first serial communication lane operating at a first speed, and a second serial communication lane operating at a second speed. The second speed is slower than the first speed. The transmitter can include bit steering logic that receives a data stream, provides a first number of bits of the data stream to the first serial communication lane, and provides a second number of bits to the second serial communication lane. The proportion of the first number of bits to the second number of bits is the same as a proportion of the first speed to the second speed.
