Stateless Message Routing via Volatile Memory and Active Connections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional message routing systems face performance bottlenecks due to slow reading and writing speeds in nonvolatile memory, leading to potential message loss and system crashes, especially in high-performance environments.
Innovation Solution
Implementing stateless message routing that avoids storing messages in nonvolatile memory by confirming delivery only after the message reaches the destination, using volatile memory for message storage and employing protocols like SMTP to manage active connections for efficient data transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If messages are stored in nonvolatile memory for recovery, then reliability is improved, but speed deteriorates due to slow read/write operations
Solution Approach 1:
The patent extracts the message storage function from nonvolatile memory by implementing stateless routing where messages are not stored in NVM. Instead, the system uses volatile memory and active connections to forward messages directly, eliminating the slow read/write operations to NVM while maintaining reliability through confirmation mechanisms.
Solution Approach 2:
The patent introduces dynamic stateless routing where the system adapts its behavior based on connection status and delivery confirmation. The router dynamically establishes active connections, forwards messages in real-time, and confirms delivery, replacing the static store-and-forward model with a dynamic approach that improves speed while maintaining reliability.
2Reliability
If traditional store-and-forward routing is used, then reliability is improved through message storage, but productivity deteriorates due to performance bottleneck
Solution Approach 1:
The patent implements continuous message forwarding through active connections without interruption for storage operations. The router continuously receives, processes, and forwards messages through established connections, eliminating the interruptions caused by NVM read/write operations and achieving high transaction throughput while maintaining delivery assurance through confirmation mechanisms.
Solution Approach 2:
The patent replaces the mechanical store-and-forward process with a stateless forwarding mechanism. Instead of physically storing messages in NVM and then retrieving them, the system uses virtual active connections to forward messages directly, substituting the storage mechanism with a connection-based transmission approach that eliminates the performance bottleneck.
3Loss of information
If nonvolatile memory storage is implemented, then data loss is prevented, but device complexity increases due to storage and retrieval operations
Solution Approach 1:
The patent removes the NVM storage component from the system by implementing stateless routing. The message forwarding function is extracted from the storage mechanism, allowing the system to forward messages through active connections without requiring NVM for persistence, thereby reducing device complexity while maintaining information integrity through confirmation protocols.
Solution Approach 2:
The patent uses confirmation messages as copies of delivery verification rather than storing actual message content in NVM. The system maintains information integrity by exchanging confirmation copies between sender and receiver, eliminating the need for complex NVM storage operations while preventing message loss through verification mechanisms.
Data Source
AI summary
Systems and methods of processing incoming data provide for receiving incoming data and determining whether to employ stateless routing of the incoming data based on one or more destination hosts associated with the incoming data. In one approach, stateless routing involves storing the incoming data only in volatile memory and withholding confirmation of receipt of the incoming data until confirmation of delivery is received from either the destination host or a downstream router. The determination as to whether stateless routing should be employed can take into consideration historical data for the destination host as well as control data. The determination can also be based on the number of destination hosts.
