Communication Device Bandwidth Measurement Cycle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication devices face challenges in stably transmitting desired data over networks due to the occupation of available bandwidth by measurement packets, leading to a lack of bandwidth for other data communications.
Innovation Solution
A communication device that alternates between measurement and non-measurement states within a predetermined cycle, allowing for the transmission of measurement packets to determine available bandwidth, and then uses a bandwidth smaller than the available bandwidth for data packet transmission during the non-measurement state, ensuring stable data communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If measurement packets are continuously transmitted to measure available bandwidth, then measurement precision is improved, but productivity deteriorates due to bandwidth occupation preventing other data communication
Solution Approach 1:
The patent implements periodic bandwidth measurement by alternating between measurement periods (where measurement packets are transmitted) and non-measurement periods (where normal data communication occurs). This periodic action allows the system to achieve measurement precision while minimizing bandwidth occupation, as measurement activities are confined to specific time windows rather than being continuous.
Solution Approach 2:
The communication process is segmented into distinct measurement periods and non-measurement periods. During measurement periods, bandwidth measurement activities are performed; during non-measurement periods, normal data communication resumes. This segmentation allows both measurement precision and data communication productivity to be maintained in their respective time segments.
2Measurement precision
If measurement packets occupy most of the available bandwidth, then measurement precision is improved, but reliability deteriorates as no bandwidth remains for other data communication
Solution Approach 1:
By implementing periodic measurement cycles with defined measurement and non-measurement periods, the system ensures that measurement activities do not continuously occupy bandwidth. During non-measurement periods, full bandwidth availability is restored for other data communication, maintaining reliability while achieving measurement precision during designated measurement windows.
Solution Approach 2:
The system performs measurement activities partially rather than continuously, using only the necessary portion of time and bandwidth required for accurate measurement. This partial action approach allows measurement precision to be achieved with minimal bandwidth occupation, leaving sufficient bandwidth for reliable other data communication.

AI summary
A communication device capable of connecting to a network includes a switching portion that switches an operation state of the communication device to one of a measurement state and a non-measurement state within a predetermined cycle, the measurement state being a state in which an available bandwidth is measured, the non-measurement state being a state in which the available bandwidth is not measured, and the available bandwidth being a bandwidth available in the network, a first transmission portion that transmits to a partner device a plurality of measurement packets while sequentially changing transmission intervals, in a state in which the operation state has been switched to the measurement state and a second transmission portion that transmits a data packet to the partner device, using a bandwidth smaller than the available bandwidth, in a state in which the operation state has been switched to the non-measurement state.
