Relay Traffic Duplication With Timed Reporting to Ease Bandwidth Congestion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing real-time traffic analysis systems face network bandwidth congestion due to immediate transmission of collected traffic information, leading to inefficient network utilization.
Innovation Solution
A communication system with a relay device that duplicates traffic and stores it locally without passing through additional relay devices, allowing transmission of traffic information to a network controller at predetermined times to avoid network congestion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If traffic information is transmitted immediately after collection, then real-time monitoring capability is improved, but network bandwidth congestion occurs
Solution Approach 1:
The system performs preliminary actions by having relay devices duplicate traffic locally and store it in local storage units before transmission. This preliminary duplication and local storage allows the main network to avoid congestion while traffic information is prepared for later transmission at predetermined intervals, resolving the contradiction between real-time monitoring and bandwidth congestion.
Solution Approach 2:
The patent introduces intermediary components (relay devices with local storage units) that act as buffers between traffic collection and transmission to the network controller. These intermediaries store duplicated traffic locally and transmit it at predetermined timings, mediating between the need for real-time data collection and the constraint of network bandwidth availability.
2Area of stationary object
If duplicated traffic passes through additional relay devices, then network coverage is improved, but transmission delay and network load increase
Solution Approach 1:
The patent extracts the traffic duplication function from the main network relay path and places it in dedicated relay devices with local storage units. By taking out the duplication operation from the critical transmission path and storing traffic locally, the system achieves wide coverage through multiple relay devices without forcing duplicated traffic through additional relay hops, thus minimizing transmission delay.
Solution Approach 2:
The system segments the traffic collection and transmission functions across multiple relay devices, each with its own local storage unit. Each relay device independently duplicates and stores traffic from its connected segments, then transmits to the network controller. This segmentation allows parallel collection from multiple sources without sequential processing delays.
3Measurement precision
If traffic is continuously monitored and transmitted, then monitoring accuracy is improved, but network energy consumption increases
Solution Approach 1:
The system implements periodic action by transmitting traffic information at predetermined timings rather than continuously. Relay devices accumulate traffic information in local storage units and transmit in periodic batches to the network controller. This periodic transmission maintains monitoring accuracy through continuous local collection while dramatically reducing network energy consumption compared to continuous transmission.

AI summary
A communication system includes a relay device having a plurality of ports and configured to duplicate traffic passing through at least one of the plurality of ports, a network controller configured to monitor traffic of a data network including the relay device, and a traffic processing device having a storage unit configured to receive and store the traffic duplicated by the relay device without passing through another relay device, and a transmission unit configured to transmit traffic information regarding the duplicated traffic obtained from the storage unit to the network controller at a predetermined timing.
