Control Apparatus for Communication Traffic Session Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Communication band congestion during simultaneous data distribution from a content server to multiple terminals leads to communication delays and increased processing load, with existing solutions requiring re-transmissions and discarding data, which are inefficient and costly.
Innovation Solution
A control apparatus with a reception part, transmission part, traffic analysis part, and transmission management part that counts communication sessions and restrains transmission until the network reaches an off-peak state, avoiding congestion by controlling transmission timing and reducing re-transmissions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data is distributed to multiple terminals simultaneously, then data distribution efficiency is improved, but communication band congestion occurs
Solution Approach 1:
The control apparatus performs preliminary actions by receiving and storing communication traffic before the network becomes congested. When congestion is detected (number of sessions exceeds threshold), the apparatus has already captured the traffic data and can resume transmission later without requiring re-transmission from the source, thus maintaining distribution efficiency while avoiding congestion.
Solution Approach 2:
The control apparatus acts as an intermediary between the data source and multiple terminals. It receives traffic, monitors session numbers, and controls transmission timing. This intermediary function allows the system to distribute data efficiently to multiple terminals while the apparatus manages congestion by pausing transmission when session thresholds are exceeded.
2Object-affected harmful factors
If congestion restriction is performed by discarding data, then communication band congestion is reduced, but re-transmission processing is required
Solution Approach 1:
Instead of discarding data during congestion, the control apparatus stores the communication traffic in memory. When congestion is detected, the apparatus retains the traffic data and resumes transmission after the number of sessions falls below the threshold. This recover approach eliminates the need for re-transmission processing that would otherwise be required if data were discarded.
Solution Approach 2:
The apparatus performs preliminary capture and storage of communication traffic before congestion causes data loss. By having the traffic already stored in memory, the system can resume transmission immediately when congestion clears, avoiding the time loss associated with re-transmission processing.
3Speed
If transmission processing is restrained until off-peak state, then communication delay is reduced, but processing load increases at the control apparatus
Solution Approach 1:
The control apparatus monitors the number of communication sessions and only restrains transmission processing when the session number exceeds a predetermined threshold. This partial action approach means the apparatus actively manages traffic only during congested periods rather than continuously, reducing overall processing load while still achieving the benefit of reduced communication delay during peak congestion.
Data Source
AI summary
A control apparatus is arranged in a predetermined network and comprises: a reception part which receives communication traffic, a transmission part which executes a transmission processing transmitting the communication traffic to a destination side, a traffic analysis part which counts a number of communication sessions within predetermined time period, included in the communication traffic, and a transmission management part which holds the communication traffic and causes the transmission part to restrain execution of the transmission processing until the network becomes an off-peak state, when the number of communication sessions exceeds a predetermined session number threshold.
