Service Switching via Control Center and Standby Unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication network service processing systems face reliability issues due to service interruptions when a service processing unit fails, leading to decreased user satisfaction and system reliability.
Innovation Solution
Implementing a system with a primary service processing unit, a physical interface card, a control center, a switching unit, and a standby service processing unit, where the control center manages the transfer of service data from the primary to the standby unit upon failure, ensuring continuous service processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single service processing unit is used, then the device complexity is reduced, but the system reliability deteriorates when the unit fails
Solution Approach 1:
A standby service processing unit is configured in advance and kept in a ready state before any failure occurs. The control center continuously monitors the primary unit's status and pre-establishes the switching mechanism, so that when failure happens, the standby unit can immediately take over without requiring complex real-time decision-making or reconfiguration
Solution Approach 2:
The control center acts as an intermediary between the primary service processing unit, the standby service processing unit, and the physical interface card. It monitors the primary unit's health status, detects failures, and manages the switching process by directing the physical interface card to redirect service data from the failed primary unit to the standby unit, thereby isolating the complexity of failure management from the data path
2Reliability
If service data is redirected to standby unit upon failure, then service continuity is improved, but the switching response time increases
Solution Approach 1:
The standby service processing unit is pre-configured with all necessary processing capabilities and connection parameters before any failure occurs. The control center maintains continuous monitoring of the primary unit's status, and the physical interface card is pre-programmed with switching rules, enabling immediate redirection of service data to the standby unit upon failure detection without requiring time-consuming reconfiguration or analysis
Solution Approach 2:
The control center continuously receives feedback signals from the primary service processing unit regarding its operational status. When the primary unit sends a failure signal or stops responding, the control center immediately detects this through the feedback mechanism and triggers the switching process, ensuring minimal detection and response time while maintaining service continuity

AI summary
A system for implementing service switching includes a primary service processing unit, a physical interface card, a control center, a switching unit and a standby service processing unit, to guarantee that the physical interface card connected to the failed primary service processing unit transmits the service data that should be processed by the primary service processing unit to the standby service processing unit, and to control the control switching unit to transmit the service data that should be transmitted to the primary service processing unit to the standby service processing unit. A method for implementing service switching includes: managing the physical interface card to transmit the service data that should be processed by the primary service processing unit to the standby service processing unit, and managing the switching unit to transmit the service data that should be transmitted to the primary service processing unit to the standby service processing unit.
