Alert Notification System with Priority-Based Throttling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing notification systems face challenges in delivering real-time alert messages across multiple channels while ensuring security, cost control, and customization based on user preferences, which are essential for maintaining strong customer relationships in segmented markets.
Innovation Solution
A multi-channel service platform that includes a throttler for managing alert message processing, an alert notification module for secure and priority-based transmission, and a token system for authentication and authorization, which customizes messages based on subscriber preferences and delivery channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If alert messages are transmitted through multiple channels simultaneously, then message delivery coverage is improved, but system complexity and processing overhead increase
Solution Approach 1:
The system segments alert messages into different priority levels (high, medium, low) and routes them through appropriate channels based on priority. The notification service divides message handling into separate processing threads for different priority levels, allowing simultaneous multi-channel transmission while managing complexity through structured segmentation of processing logic.
Solution Approach 2:
The notification service acts as an intermediary layer between the alert originator and multiple delivery channels. It receives alert messages, determines appropriate channels based on priority and subscriber preferences, and manages transmission across email, SMS, push notifications, and other channels. This intermediary structure simplifies the overall system by centralizing channel management logic.
2Speed
If priority-based message processing is implemented, then critical alert delivery speed is improved, but processing logic complexity increases
Solution Approach 1:
The system applies different processing qualities to different message priorities. High-priority messages receive immediate processing with elevated thread priority and are routed through fast channels first. Low-priority messages are processed after higher priority messages are handled. This local differentiation of processing quality achieves fast critical alert delivery without requiring complete reprocessing of all messages.
Solution Approach 2:
The notification service maintains continuous processing of alert messages through a queue-based system where messages are processed in priority order without interruption. The system continuously monitors the message queue and processes messages as they arrive, ensuring that critical alerts are handled immediately while maintaining steady processing flow for all message types.
3Reliability
If message customization based on subscriber preferences is performed, then customer relationship quality is improved, but processing time and resource consumption increase
Solution Approach 1:
Subscriber preferences and channel selections are pre-configured and stored in the system before alert messages are generated. When an alert message arrives, the notification service quickly retrieves the pre-stored preferences for the target subscriber and applies them immediately. This preliminary preparation of customization data eliminates the need for real-time preference analysis, significantly reducing processing time while maintaining personalized message delivery.
Data Source
AI summary
A system and method for providing real-time alert message to one or more subscribers in a service provider network is provided. The service provider network may be an enterprise, a communication service provider or a hosted service. A throttler application receives request for alert message generated by an alert originator application and relays the request to a gateway of an alert notification module. A token associated with the request is validated. Based on token parameter values which includes subscriber identities, delivery channel specifications, alert originator application priorities and end point identities, the alert message is customized and is presented to one or more appropriate delivery channel servers. The alert message is then delivered to the one or more subscribers.
