Single- and Multi-Node Datastore Architecture for Network Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network computing systems face challenges in efficiently storing and managing network routing information, particularly in large networks, where manual construction of routing tables is unfeasible, and dynamic routing can be computationally expensive and lacks safeguards against system failures.
Innovation Solution
Implementing a datastore architecture that offloads network routing information to a centralized database, which can be deployed as a single node or multiple nodes, allowing for flexible storage and processing of structured and unstructured data, and supports publish-subscribe messaging for efficient data distribution.

Engineering Contradiction Analysis
1Extent of automation
If dynamic routing is used to automatically construct routing tables, then the network can act autonomously in avoiding failures and blockages, but the computational overhead and complexity increase significantly
Solution Approach 1:
The patent extracts the routing table construction and storage functionality from the network devices themselves and places it in an external centralized database. This separation removes the computational burden of dynamic routing from individual devices while maintaining autonomous routing capabilities through the centralized system that collects and distributes routing information to the network.
2Ease of operation
If routing information is stored in a centralized database, then data management and distribution are simplified, but the system becomes vulnerable to single point of failure
Solution Approach 1:
The patent segments the centralized database into multiple distributed database nodes that work together as a cluster. This segmentation maintains the ease of centralized data management while eliminating the single point of failure vulnerability by distributing the data storage and management across multiple independent nodes, ensuring system reliability even if individual nodes fail.
3Reliability
If multiple alternative paths are used for routing, then network reliability and load distribution improve, but the complexity of path selection and management increases
Solution Approach 1:
The patent introduces an intermediary centralized database system that manages multiple routing paths. Instead of individual devices managing complex path selections, the intermediary database collects routing information from multiple sources, processes it, and distributes appropriate routing paths to devices. This simplifies path management at the device level while maintaining multiple alternative paths for improved reliability and load distribution.

AI summary
Systems, methods, and devices for offloading network data to a datastore. A system includes a plurality of instances of a datastore node in a single networking device, each of the plurality of instances of the datastore node comprising: a datastore; a publisher independent of the datastore for publishing data to the datastore; a subscriber independent of the datastore for receiving information from the datastore; a replicator agent configured to connect to the datastore as a publisher or a subscriber; and a persistent storage agent configured to connect to the datastore as a publisher or a subscriber.
