Solution Overview
Problem
Existing network systems face challenges in maintaining synchronized data packet transmission, leading to potential service degradation and quality of service issues due to unsynchronized data packet transmission, especially in industrial applications where predictability and latency are critical.
Innovation Solution
A method and network bridge solution that involves receiving data packets within a threshold time interval of a periodic transmission window and forwarding them in the subsequent window, using auxiliary queues to manage and prioritize data packets, ensuring defined latency and synchronization across the network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If data packets are transmitted without synchronization mechanisms, then device complexity is reduced, but service quality and reliability deteriorate due to unpredictable latency and traffic overload
Solution Approach 1:
The patent implements periodic transmission windows at network stations where data packets are transmitted in synchronized periodic intervals. Each transmission window has a defined start time and duration, creating a periodic rhythm to data transmission across the network. This periodic structure ensures that traffic from multiple stations does not collide simultaneously, maintaining service quality without requiring complex continuous synchronization protocols.
Solution Approach 2:
The patent establishes transmission windows in advance with predetermined start times and durations before data transmission begins. Network stations are configured with scheduled transmission opportunities ahead of time, allowing them to prepare and buffer data packets for transmission at the appropriate moment. This preliminary scheduling eliminates the need for real-time negotiation and complex synchronization during active data transmission.
2Reliability
If sophisticated synchronization mechanisms are implemented, then data transmission reliability is improved, but device complexity and hardware requirements increase
Solution Approach 1:
Network stations autonomously determine their own transmission windows based on pre-configured parameters such as window start times, durations, and periodic intervals. Each station independently calculates when it should transmit data packets without requiring continuous communication with a central controller or other stations. This self-service approach maintains synchronization reliability while minimizing hardware complexity by eliminating the need for sophisticated synchronization hardware.
3Speed
If data packets are forwarded immediately upon receipt, then transmission speed is improved, but synchronization and latency control deteriorate
Solution Approach 1:
The patent implements dynamic buffering and forwarding mechanisms where network bridges hold data packets temporarily until the next appropriate transmission window occurs. The forwarding timing is dynamically adjusted based on the received packet's arrival time, the current transmission window schedule, and the destination station's upcoming transmission opportunities. This dynamic approach balances immediate forwarding needs with synchronization requirements, controlling latency without sacrificing transmission speed.

AI summary
The present disclosure concerns a method of synchronization of data packet transmission (P1, P2, P3) in a network (N), including and/or initiating the acts of: Receiving (S1), e.g. from a terminal device (T1, T2, T3) of the network (N), one or more data packets (P1, P2, P3) after a threshold time interval (tt) of a periodic transmission window (RT, BE), wherein the threshold time interval (tt) is arranged at the beginning of said periodic transmission window (RT, BE), and Forwarding (S2) the data packet (P1, P2, P3) in a subsequent transmission window (RT, BE), preferably directly after the transmission window in which the data packet (P1, P2, P3) was received, within the threshold time interval (tt) of the transmission window (RT, BE).
