Solution Overview

Problem

Existing network services face inefficiencies due to static network parameters, leading to high costs and limited flexibility, especially for networks with dynamic needs, and hinder the ability to identify and defend against network threats like DDoS attacks.

Innovation Solution

Implementing blockchain-as-a-service (BaaS) to manage and enforce network parameters across administrative domains, allowing dynamic adjustments and secure communication, enabling on-demand provisioning of network resources and enhanced security measures.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If static network parameters are used, then network stability is maintained, but network flexibility and adaptability deteriorate

Engineering Contradiction:

Improvenetwork stabilityVSAvoidnetwork flexibility

Core Design Contradiction:

Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The patent implements dynamic network parameter adjustment by allowing administrative domains to modify bandwidth and other network parameters in real-time based on actual traffic demands and service requirements, transforming the static configuration model into a dynamic one that adapts continuously to changing conditions

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system establishes feedback mechanisms where network performance metrics and traffic patterns are continuously monitored, and this information feeds back into the parameter adjustment process, enabling automatic optimization of network resources without manual intervention while maintaining stability through controlled adaptation

Inventive Principle:

Principle #23Feedback

2Productivity

If network parameters are upgraded by altering subscription, then network performance is improved, but cost and time consumption increase

Engineering Contradiction:

Improvenetwork performanceVSAvoidtime consumption

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The system pre-establishes parameter adjustment capabilities and authorization frameworks within the blockchain infrastructure, so that when performance upgrades are needed, they can be executed immediately through automated smart contracts rather than requiring time-consuming subscription alteration processes

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

Administrative domains are empowered to autonomously adjust their own network parameters based on predefined policies and actual needs, eliminating the need to contact service providers or go through manual subscription changes, thus achieving rapid performance optimization without external intervention delays

Inventive Principle:

Principle #25Self-service

3Device complexity

If administrative domains cannot communicate to coordinate changes, then system simplicity is maintained, but collaboration efficiency and threat detection capability deteriorate

Engineering Contradiction:

Improvesystem simplicityVSAvoidcollaboration efficiency

Core Design Contradiction:

Device complexityVSProductivity

Solution Approach 1:

The patent introduces a blockchain-based intermediary layer that enables secure communication and coordination between administrative domains without requiring complex direct integration between each domain. The blockchain acts as a neutral mediator where domains can publish and retrieve parameter changes and security information in a standardized manner

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The blockchain infrastructure serves multiple functions simultaneously: it stores network parameter configurations, enables inter-domain communication, provides security information sharing, and facilitates coordinated changes across administrative domains, replacing multiple separate systems with a single universal platform

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

Managing policies for a chain of administrative domains, from end-to-end, includes receiving, at a network device associated with an administrative domain that is part of a chain of administrative domains provisioning an Internet-based application or an Internet-based service to a network, a root block for a blockchain. The root block is generated by a network device in the network and includes a request for a specific network parameter over a specific time period. The network device associated with the administrative domain appends a first block to the blockchain including the root block to accept the request and configures the administrative domain in accordance with the specific network parameter when an end-to-end path in the chain of administrative domains accepts the request. The network device associated with the administrative domain also generates blockchain transactions that append network status updates to the blockchain during the specific time period.
