Rendezvous Abstraction for Protocol-Independent Message Correlation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication protocols require protocol-specific mechanisms for correlating messages within message exchanges, which can be complex and vary widely, making it difficult to manage message correlations across different protocols and patterns.
Innovation Solution
A rendezvous abstraction is introduced to correlate messages independently of underlying communication protocols, allowing for a standardized approach to message exchange correlation that works across various message exchange patterns and protocols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If protocol-specific correlation mechanisms are used, then message correlation can be achieved for each protocol, but device complexity and difficulty of operation increase due to the variety of mechanisms
Solution Approach 1:
The patent introduces a universal rendezvous abstraction that can correlate messages across multiple different communication protocols and message exchange patterns. Instead of requiring separate correlation mechanisms for each protocol, the system uses a single standardized abstraction layer that handles correlation for request-reply, solicit-response, and full-duplex patterns alike, thereby reducing complexity while maintaining reliable message correlation.
Solution Approach 2:
The rendezvous abstraction acts as an intermediary between the application layer and the underlying communication protocols. It receives messages from various protocols, correlates them using the standardized abstraction, and forwards them appropriately. This mediator approach allows protocol-specific correlation details to be hidden while providing a unified correlation mechanism at the abstraction layer.
2Reliability
If protocol-specific correlation mechanisms are used, then each protocol can be optimized for its specific needs, but ease of operation deteriorates due to the need for protocol-specific customization
Solution Approach 1:
The rendezvous abstraction provides a universal interface for message correlation that works across all protocols. Application developers can use the same standardized API and correlation mechanisms regardless of whether they are working with request-reply, solicit-response, or full-duplex protocols, significantly improving ease of operation while maintaining protocol-optimized correlation behavior.
Solution Approach 2:
The system creates a standardized copy of the correlation mechanism through the rendezvous abstraction. Instead of requiring developers to implement different correlation logic for each protocol, the abstraction provides a template that can be instantiated and used uniformly across all protocols, simplifying operation while preserving the necessary correlation functionality.
3Adaptability or versatility
If multiple correlation mechanisms are supported, then adaptability to different protocols is improved, but device complexity increases
Solution Approach 1:
The rendezvous abstraction is designed to be universally applicable across all communication protocols and message exchange patterns. It provides a single standardized mechanism that adapts to handle different protocols internally, thereby improving protocol support versatility while avoiding the complexity of maintaining separate correlation mechanisms for each protocol.

AI summary
A rendezvous abstraction that is used to correlate messages within message exchange. The rendezvous abstraction may be instantiated to correlate messages regardless of the type of message exchange pattern, and regardless of the underlying protocols used to communication message. Messages exchanges of primitive protocols are modeled as unilateral message exchanges. The rendezvous abstraction is used to correlate messages of the unilateral message exchange, and serves as an abstraction that is used to represented the rendezvous point where the message of the message exchange pattern are handled. Accordingly, instead of focusing on the protocol-specific mechanisms for correlation, if even available, the application author may simply work with a standard rendezvous abstraction.
