Distributed Node Management via System View Information Exchange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In distributed computing systems, limited knowledge among compute nodes hinders efficient communication and resource management, particularly when external nodes attempt to access services, leading to inefficiencies and security concerns.
Innovation Solution
Implementing a system where internal compute nodes maintain and exchange system view information using epidemic protocols and natural interactions, with an entry point node managing access and authentication for external nodes, and using this information for decision-making and resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If compute nodes maintain limited knowledge about other nodes, then system security and privacy are improved, but communication efficiency and resource management deteriorate
Solution Approach 1:
The system segments information into two categories: system view information (public, shared knowledge about node locations, services, and capacities) and private node information (confidential operational details). This segmentation allows nodes to share sufficient information for efficient communication while maintaining security and privacy boundaries.
Solution Approach 2:
The patent introduces an intermediary mechanism where nodes exchange system view information through controlled interactions rather than direct full-information sharing. This intermediary layer of system view information enables efficient decision-making without exposing sensitive private information between nodes.
2Productivity
If compute nodes exchange more system view information, then resource allocation and workload balancing improve, but information management complexity and communication overhead increase
Solution Approach 1:
System view information serves multiple functions simultaneously: it enables node discovery, service location, workload assessment, and communication routing. This multi-functionality reduces the need for separate information exchange mechanisms for each purpose, thereby reducing overall complexity while improving resource allocation efficiency.
Solution Approach 2:
Nodes maintain system view information in advance of actual resource allocation decisions. This preliminary information gathering allows nodes to quickly make informed decisions about workload distribution and resource allocation without requiring complex real-time information exchange during critical operations.
3Adaptability or versatility
If external nodes are granted access to the distributed system, then system versatility and service availability improve, but security risks and access management complexity increase
Solution Approach 1:
The system applies different security qualities to different nodes: internal nodes receive full system view information and have unrestricted access, while external nodes receive limited system view information and have controlled access. This local differentiation of information quality and access rights enables service availability for external nodes while maintaining security through information asymmetry.

AI summary
Techniques for distributed computing system node management are described herein. In some cases, internal compute nodes (i.e., compute nodes that are allocated to the distributed system) may be mutually trusted such that they may freely establish communications with one another. By contrast, external compute nodes (i.e., compute nodes that aren't allocated to the distributed computing system) may be untrusted such that their access to the distributed system may be regulated. In some cases, one or more of the compute nodes within the distributed computing system may maintain respective collections of system view information. Each respective collection of system view information may include, for example, information associated with the corresponding compute node's view of the distributed computing system based on information that is available to the corresponding compute node.
