Client Unit Process Copying for Intelligent Network Service Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional intelligent network systems face instability and inconvenience due to the need for pre-storing copy processes in multiple server units, which can lead to service disruptions if one server unit fails, and the system cannot guarantee persistent service without all server units having a copy process.
Innovation Solution
The system includes a client unit and two server units connected over a network, where the client unit copies and stores the process from the first server unit and transfers it to a second server unit if the first server unit fails, allowing the second server unit to provide continuous service, and if no server units are available, the client unit executes the stored process to maintain service.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If copy processes are pre-stored in multiple server units to ensure service continuity, then service stability is improved, but system complexity and storage requirements increase
Solution Approach 1:
Instead of having server units store copy processes proactively, the invention inverts the approach by having the client unit store the copy process and transfer it to alternative server units only when needed (when the primary server fails). This reduces the baseline system complexity while maintaining service continuity capability.
Solution Approach 2:
The client unit performs preliminary action by storing the copy process in advance, so that when a server failure occurs, the backup process is already available for immediate transfer to alternative server units, ensuring service continuity without requiring pre-configured copies in multiple servers.
2Reliability
If copy processes are pre-stored in all available server units to handle any malfunction, then service continuity is improved, but the inconvenience of use and storage overhead increase
Solution Approach 1:
The invention applies local quality by storing the copy process locally in the client unit rather than distributing it to all server units. This localized storage approach simplifies the system while ensuring service continuity, as the copy is only needed at the client side for failover scenarios.
Solution Approach 2:
The client unit creates a copy of the process from the primary server unit and stores it locally. This copying mechanism enables the client to switch to alternative server units if needed, providing service continuity without requiring all server units to store copies, thus improving convenience.
3Reliability
If the client unit stores and executes the copied process locally when all server units are unavailable, then service availability is improved, but client-side processing load increases
Solution Approach 1:
The client unit is equipped with self-service capability to execute the copied process locally when all server units are unavailable. This self-service mechanism ensures service availability without requiring external assistance, though it does increase client-side processing load as a trade-off for maintaining availability.

AI summary
An intelligent network system including a client unit and a server unit providing a service to the client unit, and a method and computer-readable medium controlling the same are disclosed. If the server unit copies a process that performs a service requested by the client unit into the client unit, and the server unit cannot provide the service any longer, the process is copied to another available server unit so that the service can be continuously provided. Also, if there is no available server unit, the client unit receives the service using the copy process pre-stored in the client unit itself. Therefore, although the network or the peripheral device is in the worst state, the client unit can stably receive the service.
