Abstract: An optical transmission device includes: a route control unit that outputs user data including destination information to a first channel or a second channel, based on a latency associated with each destination included in the destination information; a first optical transmission unit that treats the user data as first data when the user data are output to the first channel, converts the first data into a first optical signal by first error correction coding processing and a first modulation method, and transmits the first optical signal; and a second optical transmission unit that treats the user data as second data when the user data are output to the second channel, converts the second data into a second optical signal by second error correction coding processing different from the first error correction coding processing, and a second modulation method different from the first modulation method, and transmits the second optical signal.

Abstract: Various embodiments disclosed herein provide techniques for deciding when to use FEC to transmit a message between node devices in a mesh network. In various embodiments, a method includes receiving, by a communication application executing on a first node of a mesh network, a message; determining, by the communication application, a second node in the mesh network to transmit the message to, the second node being a neighbor of the first node; determining, by the communication application based on a history of forward error correction (FEC) and non-FEC transmissions with the second node, that FEC or non-FEC should be used to transmit the message; and transmitting, by the communication application, in response to determining that FEC or non-FEC should be used to transmit the message, the message to the second node using FEC or non-FEC.

Abstract: In some aspects, the techniques described herein relate to a method including: encoding a current data portion to generate an encoded current data portion for inclusion in a data packet; encoding, based upon content of the current data portion, a forward error correction data portion for a previous data portion to generate an encoded forward error correction data portion; generating the data packet including the encoded current data portion and the encoded forward error correction data portion; and providing the data packet to a receiver.

Abstract: Disclosed are systems, methods, and non-transitory computer-readable storage media for monitoring application health via correctable errors. The method includes identifying, by a network device, a network packet associated with an application and detecting an error associated with the network packet. In response to detecting the error, the network device increments a counter associated with the application, determines an application score based at least in part on the counter, and telemeters the application score to a controller. The controller can generate a graphical interface based at least in part on the application score and a timestamp associated with the application score, wherein the graphical interface depicts a trend in correctable errors experienced by the application over a network.

Abstract: Technologies for optimizing post-FEC bit error rate performance of a Forward Error Correction (FEC) system are described. A controller is coupled to an FEC circuit and a receiver circuit. The controller receives FEC symbol error data from the receiver circuit and determines, using the FEC symbol error data, a post-FEC correlated performance metric indicative of an estimated post-FEC BER of the FEC circuit. The controller adjusts, based on the post-FEC correlated performance metric, at least one of a FEC parameter of the FEC circuit or a link parameter of the receiver circuit to decrease the estimated post-FEC BER. This improves the post-FEC BER performance of the FEC circuit.

Abstract: A network interface device comprises circuitry to add a frame check sequence value a data packet to be transmitted onto a network. The data packet with the frame check sequence value is stored in memory. Media access control layer circuitry reads the data packet from the memory and determines if the frame check sequence value is correct. When it is note correct, it is determined that the data in the data packet is corrupted.

Abstract: A method to provide flexibility on the configuration and operation of the modulator, demodulator, and modem, where purpose-built (legacy) devices are not traditionally capable of exposing a level of control and flexibly for a user or an autonomous program for optimizing performance. Providing user or programmatic control of algorithms is traditionally not possible for purpose-built modems. Parameters such as the number of decoder iterations that are performed on Forward Error Correction (FEC), Interference Mitigation algorithm, or dynamic adjustment loop bandwidth to combat phase noise can be adjusted autonomously to optimize receiver performance. The all software modem, supported by a High-Performance Computing (HPC) architecture, removes the limitation due to the flexibility of programming resources and available performance. Unlike most purpose-built hardware, the HPC allows processing resources to dynamically be reallocated, so that as additional performance is desired, the resources may be increased and decreased as required.

Abstract: A data processing method and a device, the method including determining, by an optical network unit, in a received data stream, after the optical network unit enters a pre-synchronization state, a position of a forward error correction (FEC) codeword boundary in the data stream based on a position of a physical synchronization sequence (Psync) field, performing an FEC codeword decoding check, where the Psync field is a field that matches a preset Psync, in the data stream, and entering, by the optical network unit, a synchronization state in response to an FEC codeword among N consecutive FEC codewords in the data stream passing the decoding check, where N is an integer greater than or equal to 1.
