Blockchain Node QoS Control for Lower-Latency Data Appending
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing blockchain systems experience latency issues when appending additional data, leading to delayed timing in data finalization.
Innovation Solution
A management apparatus that provides quality of service (QoS) control by issuing one-time passes to nodes within a network to enhance communication quality, reducing latency in data appending to a blockchain.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional data is forwarded within the plurality of nodes to be appended to the blockchain, then the blockchain database is updated with new transaction data, but the timing of appending the additional data is delayed due to forwarding time
Solution Approach 1:
The management apparatus preliminarily sets quality of service parameters for communication paths between nodes before data forwarding occurs. By pre-configuring QoS policies, bandwidth allocation, and priority levels for blockchain-related communication, the system ensures that data can be appended to the blockchain with minimal latency when the actual forwarding occurs, while maintaining data integrity
2Loss of time
If quality of service control is implemented to reduce latency in data appending, then the timing of appending additional data to the blockchain is accelerated, but the system complexity increases due to QoS management requirements
Solution Approach 1:
The management apparatus serves as an intermediary that centralizes QoS control functions. Instead of each node implementing complex QoS management independently, the management apparatus receives QoS control requests, determines appropriate quality parameters, and enforces them across the network. This mediator approach reduces overall system complexity while achieving the goal of reduced latency in data appending

AI summary
A management apparatus includes: a provider configured to, upon receiving a first request to control quality of communication within a group constituted by a first node and second nodes, which have a blockchain and which are configured to execute the communication for appending additional data to the blockchain, from the first node, provide the first node with first information corresponding to the first request; and a quality controller configured to set quality of communication related to a control target node that is one of the second nodes to quality better than or equal to a first quality upon receiving the first information in addition to a second request to control the quality of the communication related to the control target node from a receiving node, which has received the first information during forwarding of the first information within the group, among the second nodes.
