Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data distribution systems face instability and communication disruptions when default routing information is updated, causing temporary halts in specific data transmission, such as video streaming, and preventing communication with terminals connected via different networks.
Innovation Solution
A data distribution device with a specific data distribution unit, determining unit, and routing setting unit that maintains the default route for specific data distribution when acquiring routing information from a second network, preventing changes during active video distribution and allowing general data communication via a different network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal acquires routing information from one network and performs automatic setting, then the communication via that network is enabled, but the communication via another network is disabled
Solution Approach 1:
The patent segments the routing information into network-specific routes and default routes. Each network connection maintains its own routing information independently, allowing the terminal to preserve routing information from the first network while acquiring routing information from the second network. This segmentation prevents the automatic update of default route information from overwriting network-specific routing information, thereby maintaining communication stability across multiple networks.
Solution Approach 2:
The patent implements dynamic route selection based on the type of data being transmitted. The terminal dynamically switches between using network-specific routes for general data communication and preserving the original default route for specific data transmission. This dynamic behavior allows the system to adapt to different communication requirements while maintaining stability for time-sensitive applications like video streaming.
2Productivity
If the default route is automatically updated when connected to a second network, then general data communication is enabled, but specific data transmission (video streaming) is disrupted
Solution Approach 1:
The patent performs preliminary actions by acquiring and storing routing information from the first network before connecting to the second network. The terminal saves the default route information from the first network as a backup before the automatic update occurs. This preliminary action ensures that when the second network connection updates the routing information, the original route information is preserved and can be restored when needed for specific data transmission.
Solution Approach 2:
The patent implements a feedback mechanism where the terminal monitors the type of data being transmitted and automatically selects the appropriate routing information. When video streaming or specific data transmission is detected, the system feedback triggers the use of the preserved default route information from the first network. When general data communication is the requirement, the system uses the routing information from the second network, optimizing both communication capability and transmission stability.
3Ease of operation
If the terminal transmits all subsequent data via the second network after routing information update, then communication via the second network is established, but communication with terminals connected via the first network is disabled
Solution Approach 1:
The patent segments routing information by network source, maintaining distinct routing tables for the first network and second network. The terminal identifies and preserves network-specific routes from the first network even after connecting to the second network. This segmentation allows the system to automatically configure routing for the second network while maintaining the ability to communicate with terminals on the first network through the preserved routing information.
Data Source
AI summary
A data distribution device for stably distributing specific data such as video data is provided. Video distribution device as a data distribution device includes video distribution unit as a specific data distribution unit, video distribution determining unit as a specific data distribution determining unit, and routing setting unit. When video distribution determining unit determines that video distribution unit is distributing video data as the specific data, and when the default route information has been acquired from a second communication device connected to a second network, routing setting unit holds the default route information without changing the default route.
