AI Technical Summary
In deterministic networks, the mismatch in cycle lengths between upstream and downstream devices can lead to infinite delay and continuous congestion due to clock errors, especially when the upstream device has a shorter cycle length than the downstream device.
A packet transmission method where a second device receives packets from a first device and determines a new cycle label based on a condition met by the packet number, allowing it to send the packets in a different cycle that aligns with the downstream device's cycle, thus avoiding congestion and delay.
This method effectively eliminates the problem of increasing delay and congestion by allowing the second device to dynamically adjust the cycle mapping relationship, ensuring that packets are sent within the correct cycle without relying on time synchronization.
