Logical Broker for Dynamic Message Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional messaging systems face inefficiencies and security risks when message consumers are mobile, as they require manual reconfiguration of communication routes, leading to unnecessary resource usage and increased security risks due to messages being forwarded to and stored on multiple servers.
Innovation Solution
Implementing a dynamic messaging routing system where brokers dynamically track the connection status and message acceptance criteria of consumers, routing messages only along paths leading to the consumer, and propagating these criteria throughout the network to ensure efficient and secure message delivery, effectively creating a single logical broker from the consumer's perspective.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If messages are distributed to all messaging servers in the network, then message consumers receive messages regardless of which server they are connected to, but system resources such as communication bandwidth, processing and storage resources are inefficiently and unnecessarily used
Solution Approach 1:
The system dynamically determines message routing based on the consumer's current connection status. The broker receives information about which servers the consumer is currently connected to and routes messages only to those specific servers, rather than distributing to all servers statically. This dynamic adaptation resolves the contradiction by making message delivery reliable (messages reach the consumer wherever connected) while avoiding unnecessary resource consumption (messages not sent to disconnected servers).
Solution Approach 2:
The routing parameters are changed from a static configuration (messages sent to all servers) to a dynamic configuration (messages sent only to currently connected servers). The broker continuously updates routing decisions based on real-time connection status information, changing the delivery parameters adaptively to match the consumer's actual location, thereby resolving the resource efficiency problem while maintaining delivery reliability.
2Adaptability or versatility
If messages are distributed to all messaging servers in the network, then message consumers receive messages no matter which server they are connected to, but security risks increase as messages traverse communications links between messaging servers and are stored on messaging servers that do not lead to the message consumer
Solution Approach 1:
The system dynamically adjusts message routing based on real-time connection information. The broker receives and processes connection status data to determine the optimal routing path, ensuring messages travel only through necessary communication links and are stored only on servers where the consumer is currently connected. This eliminates the security risks of static distribution while maintaining delivery reliability.
Solution Approach 2:
The harmful aspect of distributing messages to all servers is extracted and eliminated. The system extracts only the necessary routing information (which servers are currently connected to the consumer) and uses this to filter out unnecessary message transmissions. Messages are taken out of the distribution path for servers that don't need them, thereby removing the security risks associated with unnecessary message storage and transmission while preserving reliable delivery.
3Adaptability or versatility
If the messaging network is manually reconfigured to route messages to a non-home server, then the message consumer receives messages at the new location, but the reconfiguring process is complicated and time consuming
Solution Approach 1:
The messaging system performs self-service by automatically detecting when a consumer connects to a non-home server and dynamically adjusting the message routing accordingly. The broker receives connection status information and autonomously determines the appropriate routing configuration without requiring manual administrator intervention. This eliminates the complexity and time consumption of manual reconfiguration while maintaining full routing flexibility to support mobile consumers.
Solution Approach 2:
The system implements feedback mechanisms where the broker continuously receives information about consumer connection status and uses this feedback to automatically adjust routing decisions. When the consumer connects to a different server, this feedback triggers automatic routing reconfiguration. This closed-loop feedback system resolves the contradiction by providing routing flexibility through automatic adaptation while eliminating manual reconfiguration complexity.

AI summary
Systems and methods are disclosed that provide a single logical broker from the point of view of a message consumer connected to a messaging network. The messaging network implements dynamic routing that adapts to changes in the message preferences of the message consumer and the message consumer's availability throughout the messaging network. In various embodiments, the connection/disconnection of a message consumer and/or changes to message routing criteria at any broker in the network are propagated to all other brokers in the network until the entire network is adapted, such that a message consumer may connect to any broker node and receive the same network service and functionality regardless of connection point.
