Dynamic Subscription Management for Reducing Network Traffic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In group-based communication platforms, the increasing number of objects monitored by users leads to high processing burdens and network traffic on client devices, with many updates being irrelevant to user interests, causing unnecessary data transmission.
Innovation Solution
A dynamic subscription management system that adjusts subscriptions based on user interactions, using trigger events to generate subscribe and unsubscribe requests, ensuring only relevant object updates are transmitted to client devices via a websocket connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all object updates are transmitted to client devices, then users receive complete information, but network traffic and processing burden increase significantly
Solution Approach 1:
The system extracts and transmits only the relevant subset of object updates that match user subscriptions, rather than transmitting all updates. The server identifies which objects a user is subscribed to and selectively sends updates only for those specific objects, filtering out irrelevant data to reduce network traffic while maintaining information completeness for subscribed content.
Solution Approach 2:
The system segments the broad category of 'object updates' into individual object-specific update streams. Each object maintains its own update notification mechanism, allowing the server to send updates for specific objects only to users who have subscribed to those particular objects, rather than broadcasting all updates to all users.
2Loss of energy
If subscriptions are dynamically adjusted based on user interactions, then network traffic is reduced, but system complexity increases
Solution Approach 1:
The subscription system is designed to be dynamic rather than static. Users can subscribe to and unsubscribe from objects at any time based on their changing interests or needs. The server continuously monitors subscription status and automatically adjusts which update streams are active, allowing the system to adapt to user behavior without requiring complex manual reconfiguration.
Solution Approach 2:
The system implements feedback mechanisms where user interactions (such as viewing, liking, or sharing objects) are monitored and used to automatically adjust subscription status. When users interact with objects in certain ways, the system interprets this as interest and automatically subscribes them to relevant update streams, reducing the need for explicit user configuration while maintaining relevance.
3Loss of energy
If trigger events are used to generate subscription requests, then relevant updates are transmitted, but processing burden on client devices increases
Solution Approach 1:
Instead of having client devices continuously monitor for trigger events and generate subscription requests, the system inverts the approach by having the server push updates proactively when objects change. The server monitors object state changes and automatically notifies subscribed clients, reversing the traditional pull-based model to reduce client-side processing requirements while maintaining real-time update delivery.

AI summary
Updating object subscriptions based on trigger events is described. An indication of a trigger event, associated with an object, can be received from a client of a user. The object can be associated with current object data that is stored in a storage area of a subscription management system. The storage area can maintain the current object data for at least the object and a subscription list for client(s), wherein the subscription list for each of the client(s) comprises object identifiers corresponding to subscribed objects for each of the client(s). Based at least partly on receiving the indication of the trigger event and determining that the trigger event is associated with a modification to a subscription, the subscription list can be updated to generate an updated subscription list for the client and current object data for the subscribed objects identified within the updated subscription list can be provided thereto.
