Network Traffic Data Units Synchronized Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Network latency issues cause timing synchronization problems when distributing network traffic data units to recipients, leading to unfair advantages in scenarios like financial trading, where timely information delivery is critical.
Innovation Solution
A data processing device adds presentation timestamps to outgoing network traffic data units, indicating a future transmission time to ensure synchronized delivery, and ingress timestamps to received data units to process them in the order of receipt at the edge devices, mitigating latency-induced unfairness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If network traffic data units are transmitted immediately upon receipt or generation, then transmission speed is improved, but timing synchronization deteriorates causing unfair advantages to some recipients
Solution Approach 1:
The patent applies preliminary action by adding presentation timestamps to data units before transmission, indicating a future time when the data should be delivered. This allows the system to prepare and schedule data units in advance, ensuring they are transmitted at the correct synchronized time rather than immediately, thus resolving the contradiction between transmission speed and timing synchronization.
Solution Approach 2:
The patent uses presentation timestamps as an intermediary mechanism between data generation and transmission. These timestamps act as a mediator that decouples the immediate transmission冲动 from the requirement for synchronized delivery, allowing data units to be queued and transmitted at the appropriate time to maintain fairness across all recipients.
2Productivity
If data units are transmitted without delay, then productivity is improved, but fairness among recipients deteriorates due to latency variations
Solution Approach 1:
By adding presentation timestamps in advance that indicate future delivery times, the system can efficiently process and queue multiple data units without immediate transmission. This preliminary timestamping allows batch processing and synchronized delivery at predetermined times, maintaining both productivity through efficient processing and fairness through simultaneous delivery to all recipients.
Solution Approach 2:
The patent changes the time parameter of data transmission by using presentation timestamps to specify future delivery times. This parameter change allows the system to defer transmission from immediate to scheduled times, ensuring that data units are delivered simultaneously to all recipients despite varying network latencies, thus maintaining fairness while preserving productivity through efficient queue management.
3Measurement precision
If ingress timestamps are added to all received data units, then processing order accuracy is improved, but device complexity increases
Solution Approach 1:
The patent extracts only the essential timing information by adding ingress timestamps that record receipt times at edge devices. This extracted timestamp data is then used by the data processing device to reorder data units based on their actual receipt sequence. By extracting and utilizing only this critical timing parameter, the system achieves accurate processing order without implementing complex processing mechanisms at every device.
