Decentralized Control-Plane Messaging for Disconnected Node State Sync
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing control plane protocols for isolated or disconnected environments in information handling systems fail to effectively manage communication and reconcile states across nodes due to imperfect connectivity, leading to conflicts and delays, especially in large and distributed systems with varying authority levels and inconsistent data replication.
Innovation Solution
A decentralized control plane protocol that uses stateful, idempotent messaging to decouple message delivery from network connectivity, employing cryptographically signed requests and certificates to authenticate and validate message states, allowing secure communication and request resolution across nodes with varying trust levels and connectivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing control plane protocols are used in isolated or disconnected environments, then basic communication can occur, but conflicts and delays arise due to imperfect connectivity and inability to reconcile states across nodes
Solution Approach 1:
The patent applies preliminary action by embedding the complete desired end state directly into the request message before transmission. This allows the receiving node to execute the request without needing real-time communication or state reconciliation, resolving conflicts proactively by defining the target state upfront. The stateful, idempotent messaging ensures that even in disconnected environments, requests can be queued and executed reliably without causing conflicts.
2Reliability
If cryptographic verification and state validation are implemented, then message authenticity and security are improved, but processing time and computational overhead increase
Solution Approach 1:
The patent applies preliminary action by performing cryptographic signing of request messages at the source node before transmission. This pre-verification ensures that when the message arrives at the receiving node, authentication is immediate and does not require time-consuming verification processes. The state validation is also prepared in advance by embedding the desired state in the request, allowing for efficient comparison rather than complex reconciliation processes.
Data Source
AI summary
An information handling system of a multiple node environment includes a memory and a processor. The memory stores one or more variables associated with a state of the information handling system. The processor receives a cryptographically signed message. A source of the cryptographically signed message is considered as an untrusted source within the multiple node environment. The processor verifies the cryptographically signed message as an authoritative message. In response to the cryptographically signed message being verified as an authoritative message, the processor determines the state described in the cryptographically signed message matches the state of the information handling system stored in the memory. In response to the state described within the cryptographically signed message matches a current system state, the processor executes a request associated with the cryptographically signed message.
