Event Packet Identification in Periodic Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for detecting packet loss in event data transmitted in response to events are delayed due to varying packet group sizes and the inability to add marker bits to single event packets, leading to prolonged detection times.
Innovation Solution
A transmission apparatus generates identification information for event data and includes it in periodic data, allowing the receiving apparatus to identify and detect lost event packets more promptly by analyzing the identification information within the periodic data packets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the number of packets in event data varies depending on the event, then the system can handle diverse events flexibly, but the time required to detect packet loss increases
Solution Approach 1:
The receiving apparatus preliminarily determines the expected number of packets for each event type based on historical data or event characteristics. When a packet is lost, the apparatus can immediately detect it by comparing the received packet count against the predetermined expectation, rather than waiting for the event to complete naturally. This preliminary setup enables faster packet loss detection while maintaining the ability to handle various event types with different packet counts.
2Loss of energy
If only one packet is transmitted for event data, then transmission overhead is reduced, but marker bits cannot be added to identify head and tail packets
Solution Approach 1:
The receiving apparatus applies different processing logic based on the number of packets received for an event. When only one packet is transmitted, the apparatus uses simplified detection methods appropriate for single-packet events. When multiple packets are transmitted, the apparatus applies more sophisticated detection methods. This localized adaptation of detection strategies allows the system to handle both cases efficiently without requiring complex infrastructure for all scenarios.
3Measurement precision
If the predicted period of time for receiving tail packet is extended to accommodate varying packet counts, then packet loss detection accuracy is improved, but detection time increases
Solution Approach 1:
The receiving apparatus dynamically adjusts the expected time period for receiving packets based on the specific event type and its characteristics. Rather than using a fixed extended time period for all events, the system adapts the time window to match the typical duration of each event type. This dynamic adjustment maintains detection accuracy by accounting for packet count variations while minimizing unnecessary waiting time for each specific event scenario.

AI summary
In a transmission apparatus for transmitting periodical data transmitted at predetermined intervals and event data transmitted in response to occurrence of an event, an information generation unit generates identification information for a receiving apparatus to identify transmitted event data, and a control unit includes the generated identification information in the periodical data in response to generation of identification information by the identification information generation unit.
