METHOD OF TRANSMITTING DATA Russian patent published in 2018 - IPC H04L12/70 H04L12/865 H04L1/00 

FIELD: data processing.

SUBSTANCE: invention relates to the transmission of data, specifically to protocols used in transmitting and receiving data. Method for data transmission consisting in the use of a network transport protocol (NTP); in providing transmission of control commands, data packets, SpaceWire timestamps, SpaceWire interrupt codes and their confirmation on all nodes of the network; wherein transmission of information messages and control commands is provided in accordance with the service qualities that are customised according to the requirements and before sending, each information packet is written to the corresponding logical buffer on the transmitter; in ensuring guaranteed delivery of data, each packet is stored in a corresponding buffer on the transmitter during the lifetime determined by the timer, which counts the time until the packet with this information is relevant for transmission over the SpaceWire network; in the case of guaranteed data delivery, ensuring the correct delivery of data by sending confirmation packets, as well as re-sending the data by the source in the absence of confirmation; in the case of non-guaranteed delivery of data, confirmation of the correct delivery of data is not provided; when receiving an information packet that does not require confirmation, the data is checked and, if an error is detected in the received data packet, the packet data is transmitted to the application layer with an error notification; on the receiving side of the NTP, all types of information packets are written to a single buffer; providing configuration of the NTP with configuration parameters, providing reset of all NTP settings, clearing of all NTP buffers and resetting timers by special commands.

EFFECT: high reliability of transmitting information.
