Communication Device Bandwidth Calculation Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication devices face challenges in accurately calculating available bandwidth when received packets arrive at shorter intervals than the processing time, leading to packet loss and improper bandwidth calculation.
Innovation Solution
A communication device with reception means, first and second available band calculation means, and calculation means determination means that determines which method to use based on packet reception states, calculating bandwidth either by reception intervals between packets or by the time and size of received packet series.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If packets are transmitted at shorter intervals to increase transmission efficiency, then transmission speed is improved, but packet loss occurs due to processing time constraints
Solution Approach 1:
The patent implements dynamic adjustment of available band calculation methods based on real-time packet reception states. When packet loss is detected, the system switches from interval-based calculation to size-based calculation, and vice versa. This dynamic adaptation allows the system to maintain reliable bandwidth measurement across varying transmission conditions without sacrificing transmission speed.
2Device complexity
If a single available band calculation method is used, then device complexity is reduced, but measurement precision deteriorates under varying packet reception conditions
Solution Approach 1:
The patent changes the calculation parameters based on packet reception states. When packet loss occurs, the system switches from using reception intervals as the calculation parameter to using packet sizes and reception time as parameters. This parameter change allows accurate available band measurement under different network conditions while maintaining a relatively simple dual-method calculation structure.
Solution Approach 2:
The patent creates a universal available band calculation system that can operate under multiple packet reception conditions using two calculation methods. The first method (interval-based) works well when packets are received without loss, while the second method (size-based) works when packet loss occurs. The calculation means determination unit selects the appropriate method, making the system universally applicable to various network conditions.
3Ease of operation
If packet loss is ignored to simplify the calculation process, then ease of operation is improved, but measurement precision deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where the calculation means determination unit continuously monitors packet reception states and switches calculation methods accordingly. When packet loss is detected, the system provides feedback to switch from the simpler interval-based method to the more accurate size-based method. This feedback loop maintains calculation accuracy without requiring complex manual intervention, as the system automatically adapts based on reception conditions.

AI summary
A reception unit 11 receives transmitted packets. A first available band calculation unit 12 and a second available band calculation unit 13 calculate an available band for a transmission source of the packets. A calculation means determination unit 14 determines, on the basis of the reception states of the packets transmitted at predetermined time intervals in the reception unit 11, whether the first available band calculation unit 12 calculates the available band or the second available band calculation unit 13 calculates the available band. The first available band calculation unit 12 calculates the available band on the basis of a reception interval between the packets. The second available band calculation unit 13 calculates the available band on the basis of a time required for the reception of the transmitted series of packets and the sizes of the series of the packets.
