Message Redundancy Using Tap-Verified Backup Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data communication systems face significant latency issues due to the creation and transmission of backup messages, which are exacerbated by remote backup systems, making them unsuitable for time-sensitive communications.
Innovation Solution
A communication system that includes a first communication device configured to send a backup message to a backup device before sending the original message to the destination, with confirmation of the backup message's transmission via a tapping device, ensuring high reliability and reducing latency by assuming the backup message will reach the backup device once sent.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If backup messages are sent before original messages to ensure data reliability, then the reliability of data transmission is improved, but the transmission latency increases
Solution Approach 1:
The system sends backup messages before original messages to backup devices in advance. This preliminary action ensures that if the original message is lost, a verified copy already exists at the backup device, thereby improving transmission reliability without adding latency to the critical path of original message delivery.
Solution Approach 2:
The system creates tap copies of backup messages through tapping devices that monitor and verify the backup message transmission independently. This copying mechanism provides verification of backup message delivery without requiring the original message transmission to wait for backup confirmation, thus maintaining low latency while ensuring reliability.
2Reliability
If tap copies of backup messages are verified before sending original messages, then the reliability of message delivery is improved, but the transmission speed decreases
Solution Approach 1:
The tapping device provides feedback about the backup message transmission status to the communication device. This feedback mechanism allows the system to verify backup message delivery independently, ensuring reliability while allowing the original message transmission to proceed based on this feedback rather than waiting for full confirmation.
Solution Approach 2:
The tapping device acts as an intermediary that monitors and verifies backup message transmission separately from the main communication path. This intermediary verification process ensures backup message integrity without becoming a bottleneck for original message transmission, thus maintaining high transmission speed while improving reliability.

AI summary
Systems, methods, and devices for communication are described. A communication system includes a first communication device configured to communicate with a backup device and a destination; and a first tapping device for monitoring messages sent over a first communication link between the first communication device and the backup device. The first communication device includes at least one processor configured to: before sending a first message destined for the destination, send a backup message corresponding to the first message over the communication link for backup at the backup device; and upon confirmation of a tap copy of the backup message from the first tapping device, send the first message to the destination.
