Deterministic Network Route Setup via Time-Triggered Connection Manager
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In large computer networks, establishing deterministic communication routes with guaranteed bandwidth and minimal delay is challenging, especially in decentralized systems like the Internet, where central authority control is absent, and phase-synchronous transmission requires global time precision to minimize latency.
Innovation Solution
The method employs a self-organizing process using a Time-Triggered Connection Manager (TTCM) to dynamically build deterministic time-controlled communication routes by sending Reservation and Accept messages to network switches, adjusting phase and message length to minimize dwell time and ensure quality of service without a central planning authority.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a deterministic communication route is established in a large decentralized computer network, then guaranteed bandwidth and minimal delay are achieved, but the complexity of route establishment and coordination increases
Solution Approach 1:
The patent applies preliminary action by having the source end system pre-determine route parameters (starting time, end time, desired bandwidth) and pre-coordinate with network switches before actual message transmission. The Reservation phase allows switches to reserve resources in advance, and the Accept phase confirms commitments before the deployment period begins, ensuring deterministic guarantees without real-time coordination complexity
Solution Approach 2:
The patent implements feedback through the iterative reservation process where switches report their actual dwell time (TVD) and provide suggestions for phase and period adjustments. The source end system uses this feedback to modify reservation requests in subsequent iterations, optimizing the route parameters based on actual network conditions while maintaining deterministic guarantees
2Loss of time
If phase-synchronous transmission is implemented across all switches, then message latency is minimized, but the requirement for global time precision and coordination increases
Solution Approach 1:
The patent applies preliminary action by establishing phase and period parameters in advance during the Reservation phase. The source end system determines initial phase values and message lengths before transmission begins, allowing switches to pre-synchronize their timing without requiring complex real-time coordination during actual message flow
Solution Approach 2:
The patent uses parameter changes by allowing the source end system to modify phase and message length parameters based on feedback from switches about actual dwell times. This iterative adjustment of timing parameters optimizes latency while maintaining the phase-synchronous transmission structure across all network switches

AI summary
The invention relates to a method for establishing deterministic communication routes in a large computer network, wherein all affected end systems and switches of the computer network have a global time and a deterministic communication route is generated on the basis of an existing communication route between two or more end systems of the computer network in that a time-triggered connection manager (TTCM) of an end system reserves the deterministic communication route in a reservation phase by sending a reservation message to each network switch of the existing communication route up to the reservation commitment time (KZPT), and then confirms this deterministic communication route in an accept phase by sending an accept message to the network switches of the existing communication route before the KZPT.
