Time Slot Segmentation for Predictable Network Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network communication methods, such as polling and event-driven protocols, face challenges in providing time-predictable and rapid data transmission, especially in wireless networks, where delays can occur due to fixed time slots and high latency.
Innovation Solution
A network configuration with designated communication time slots, including a reserved first message time slot for specific clients and a second message time slot for multiple clients, allowing predictable data transmission and immediate event reporting without waiting for assigned time slots.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If fixed time slots are assigned to each client for data transmission, then communication predictability is improved, but transmission latency increases for random events
Solution Approach 1:
The communication time slot is segmented into two distinct message time slots: a first message time slot for dedicated client communication and a second message time slot for shared multi-client communication. This segmentation allows the system to provide both predictable dedicated transmission paths and efficient shared transmission opportunities, resolving the contradiction between communication predictability and transmission latency.
2Device complexity
If a polling method is used for client communication, then protocol overhead is reduced, but communication time increases for large data exchanges
Solution Approach 1:
The system preliminarily allocates specific first message time slots to individual clients in advance, allowing them to transmit data without waiting for polling cycles. This preliminary assignment of transmission opportunities reduces the communication time for large data exchanges while maintaining low protocol overhead, as clients know their designated transmission slots beforehand.

AI summary
The invention relates to a network comprising at least one first client and at least two second clients connected to the first client by a message transmission device, wherein the network is configured such that there is communication between the first client and the second clients in a communication time slot and data can be transmitted between the first client and the second clients in the communication time slot, said communication time slot having at least one first message time slot and one second message time slot, wherein the first message time slot can be used by a selected second client to transmit a message to the first client and the second message time slot can be used by a plurality of second clients to transmit a message to the first client.
