Technologies for scheduling time sensitive cyclical network traffic in real-time

One or more machine-readable storage media comprising a plurality of instructions stored thereon that, in response to being executed, cause an internet-of-things (IoT) device to:

• collect, by a sensor of the IoT device, sensor data;
• store the collected sensor data in a data buffer associated with a data storage device of the IoT device;
• allocate a packet descriptor for the sensor data;
• populate the allocated packet descriptor with a header field, a cyclic data port pointer, and a tail field, wherein the cyclic data port pointer indicates a location of the data buffer at which the sensor data has been stored;
• queue the packet descriptor into a media access control (MAC) unit transmit direct memory access (DMA) of the IoT device;
• fetch the sensor data from the data buffer based on the cyclic data port pointer;
• packetize the fetched data, the tail field, and the header field to form a network packet;
• transmit, based on a launch time, the network packet to a target computing device;
• update the launch time as a function of a cycle period;
• and
• requeue the packet descriptor into the MAC unit transmit DMA.

A method for scheduling time-sensitive cyclical network traffic in real-time, the method comprising:

• collecting, by a sensor of an internet-of-things (IoT) device, sensor data;
• storing, by the IoT device, the collected sensor data in a data buffer associated with a data storage device of the IoT device;
• allocating, by the IoT device, a packet descriptor for the sensor data;
• populating, by the IoT device, the allocated packet descriptor with a header field, a cyclic data port pointer, and a tail field, wherein the cyclic data port pointer indicates a location of the data buffer at which the sensor data has been stored;
• queueing, by the IoT device, the packet descriptor into a media access control (MAC) unit transmit direct memory access (DMA) of the IoT device;
• fetching, by the IoT device, the sensor data from the data buffer based on the cyclic data port pointer;
• packetizing, by the IoT device, the fetched data, the tail field, and the header field to form a network packet;
• transmitting, by the IoT device and based on a launch time, the network packet to a target computing device;
• updating, by the IoT device, the launch time as a function of a cycle period;
• and
• requeueing, by the IoT device, the packet descriptor into the MAC unit transmit DMA.
