Hierarchical Quota Node Delegation for Throughput
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In hierarchical quota systems, the existing resource allocation methods lead to inter-node communication storms, resulting in slowed system throughput due to the need for multiple nodes to check and update resource allocation records across a network, especially when nodes are geographically distributed.
Innovation Solution
Implement a method where each quota node in a hierarchical system can independently manage resource allocation by granting quota delegations to lower-layer nodes, allowing them to determine if requested resources exceed their specified quotas without needing to communicate with upper-layer nodes for every allocation request.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If all quota nodes check and update resource allocation records across the network for every allocation request, then resource allocation accuracy is maintained, but system throughput deteriorates due to inter-node communication storms
Solution Approach 1:
The patent segments the centralized quota verification process into distributed autonomous verification at each quota node. Each node maintains its own quota database and independently verifies allocation requests against its local quota records, eliminating the need for all nodes to communicate with every other node for each allocation request. This segmentation resolves the contradiction by maintaining allocation accuracy through local verification while preventing communication storms.
Solution Approach 2:
The patent implements preliminary action by having quota nodes pre-fetch and cache quota-related data before allocation requests occur. Nodes proactively retrieve and store quota limits, usage statistics, and allocation rules in their local databases in advance, so that when allocation requests arrive, verification can proceed immediately using pre-prepared data rather than requiring real-time network queries to all nodes.
2Adaptability or versatility
If quota nodes are geographically distributed across different locations, then system scalability and accessibility are improved, but communication latency and network dependency increase
Solution Approach 1:
The patent segments the monolithic quota management system into geographically distributed autonomous nodes, each capable of independent operation. Each quota node maintains its own database and verification logic, allowing the system to scale across multiple locations without requiring centralized coordination for every operation. This segmentation enables geographical distribution while minimizing network dependency.
Solution Approach 2:
The patent implements self-service by enabling each quota node to independently verify allocation requests against its own local quota database without requiring external validation from other nodes. Nodes autonomously manage their own quota records, perform local verification, and enforce allocation rules independently, eliminating the need for inter-node communication during allocation operations and thus reducing communication latency.
3Reliability
If multiple nodes update resource allocation records simultaneously across the network, then resource allocation comprehensiveness is maintained, but network traffic and processing overhead increase
Solution Approach 1:
The patent segments the centralized update process into distributed independent update operations at each quota node. Each node maintains its own quota database and updates its local records independently based on allocation requests it receives. This segmentation maintains allocation comprehensiveness through local record-keeping while eliminating the need for coordinated network-wide updates, thus reducing network traffic and processing overhead.

AI summary
A method for managing resource allocation in a hierarchical quota system, comprising n layers of quota nodes, n being a positive integer greater than 1, and comprises at a first quota node in an ith layer of quota nodes, in response to receiving a resource allocation request from a user, determining whether an amount of requested resources exceeds a first quota; if the amount of requested resources does not exceed the first quota, determining whether the first node holds a quota delegation for the first quota node; if the first node holds the quota delegation, determining whether the amount of requested resources exceeds a second quota specified by the quota delegation for the first quota node; if the amount of requested resources does not exceed the second quota, allocating the requested resources to the user.
