Command Transmission Control for Overlapping Device Groups
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing systems face network congestion due to overlapping data transfers when devices belong to multiple groups, as data acquisition requests for each group necessitate redundant data transfers.
Innovation Solution
An information processing apparatus with command receiving, device identifying, and command transmission controlling means that identifies devices belonging to multiple groups and prevents overlapping command transmissions, thereby reducing redundant data transfers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data acquisition requests are performed for each device group separately, then complete data collection for each group is achieved, but overlapping data transfers occur causing network congestion
Solution Approach 1:
The patent merges overlapping data transfer operations by identifying devices that belong to multiple device groups and consolidating their data acquisition into a single transfer operation. The command transmission controlling means detects when the same device is targeted by multiple group commands and combines these requests, ensuring the device transmits data only once even though it belongs to multiple groups. This resolving of overlapping operations maintains complete data collection while eliminating redundant network traffic.
2Reliability
If commands are transmitted to all devices in multiple groups independently, then each group receives complete command coverage, but redundant commands are sent to overlapping devices
Solution Approach 1:
The patent extracts and identifies the overlapping portion - devices that belong to multiple device groups - and handles them separately from the non-overlapping devices. The device identifying means detects devices present in multiple groups, and the command transmission controlling means transmits commands to these overlapping devices only once, while still ensuring they receive the necessary command coverage. This extraction of the redundant portion eliminates unnecessary network bandwidth consumption while maintaining complete command delivery.
3Productivity
If batch transmission is implemented for device groups, then transmission efficiency is improved, but devices in multiple groups still receive overlapping transmissions
Solution Approach 1:
The patent performs preliminary identification of overlapping devices before executing batch transmission operations. The device identifying means预先 detects which devices belong to multiple groups, and this information is stored and used during the batch transmission phase. The command transmission controlling means uses this pre-identified information to adjust the batch transmission, ensuring overlapping devices are included only once. This preliminary action simplifies the transmission control logic by preparing the overlapping device list in advance, making the batch transmission process more manageable despite the complexity of multiple group memberships.

AI summary
According to the present invention, congestion in a network band is suppressed. This information processing apparatus is provided with: a command reception unit that receives commands from at least one application given to at least two device groups; a device specification unit that specifies devices belonging to the at least two device groups when the commands from the at least one application given to the at least two device groups are of a similar type; and a command transmission control unit that executes control transmission so as to prevent overlap of transmission of the commands to the specified devices.
