Minimizing latency asymmetries in bi-directional communication system
A recently granted patent (Publication Number: US11996884B1) discloses a communication system that involves two network nodes connected through an optical communication network. The first network node sets values for specific bits in packets to determine a transmitter interval period, while the second network node receives these packets and calculates a receiver interval period based on the set bit values. The system can determine a variable latency based on these intervals and adjust subsequent data transmission accordingly. The patent details the method of setting these bit values in packet headers to establish intervals and manage latency effectively.
Furthermore, the patent describes an optical network device with processors and memory storing instructions to determine variable latencies for communication with network devices based on markers inserted in transmitted packets. These markers, represented by toggled bits in packet headers, help in adjusting the timing of data transmissions to compensate for latency. The device can differentiate between subcarriers for different network nodes and manage variable latencies accordingly. The patent highlights the importance of marker placement and manipulation in packet headers to optimize communication timing and latency adjustments within optical network systems.
