Communication Management Apparatus Bandwidth Control via Direct Link Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems using Web browser APIs struggle to optimize bandwidth control due to security and privacy restrictions, limiting access to network topology information and requiring special relay apparatuses for Quality of Service (QoS) management.
Innovation Solution
A communication management apparatus and method that determines whether terminal apparatuses can communicate directly, allowing for bandwidth restriction based on network topology, thereby optimizing bandwidth control without needing a special relay for QoS management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If Web browser APIs are used for communication, then security and privacy are improved, but bandwidth control capability deteriorates due to restricted access to network topology information
Solution Approach 1:
The patent introduces a communication management apparatus as an intermediary between terminal apparatuses. This mediator collects network topology information from terminals and performs bandwidth control based on this information, while terminals continue to use Web browser APIs for communication without direct access to topology data. The intermediary resolves the contradiction by enabling bandwidth control capability without compromising the security and privacy benefits of Web browser API usage.
2Ease of operation
If a special relay apparatus is deployed for QoS management, then bandwidth control capability is improved, but device complexity increases
Solution Approach 1:
The communication management apparatus performs multiple functions including network topology information collection, bandwidth control, and communication management. By consolidating these functions into a single multi-functional apparatus rather than requiring separate specialized relay devices for each function, the patent reduces overall device complexity while maintaining bandwidth control capability.
3Productivity
If direct communication between terminal apparatuses is enabled, then communication efficiency is improved, but bandwidth management capability deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where terminal apparatuses report network topology information to the communication management apparatus. Based on this feedback, the management apparatus determines whether to allow direct communication or relayed communication and adjusts bandwidth allocation accordingly. This feedback loop enables bandwidth management capability to be maintained even when direct communication paths are established, as the management apparatus can dynamically control bandwidth based on reported topology changes.
Data Source
AI summary
A communication management apparatus includes circuitry that manages first communication in which a terminal apparatus transmits content data to another terminal apparatus via a relay apparatus. The circuitry receives, from the terminal apparatus, a determination of whether the terminal apparatus is communicable with the another terminal apparatus through second communication that bypasses the relay apparatus. Based on a determination that the terminal apparatus is communicable with the another terminal apparatus through the second communication, the circuitry restricts a communication bandwidth for the first communication of the another terminal apparatus determined to be communicable with the terminal apparatus through the second communication.
