Solution Overview

Problem

Conventional resource allocation technologies in virtualized communication networks do not consider the importance of policies applied to each domain, leading to suboptimal resource allocation decisions that may prioritize total resource usage over domain-specific policy importance.

Innovation Solution

A resource allocation device that splits resource requirements by domain-specific policies, calculates resource allocations for each domain, evaluates solution candidates based on policy conformance, and selects the best solution by weighting evaluation values according to policy importance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If a single policy is applied to the entire network to minimize total resource consumption, then overall resource efficiency is improved, but domain-specific policy requirements cannot be satisfied

Engineering Contradiction:

Improvetotal resource consumptionVSAvoiddomain-specific policy satisfaction

Core Design Contradiction:

Quantity of substanceVSAdaptability or versatility

Solution Approach 1:

The patent divides the network into multiple domains, each with its own policy requirements. The resource allocation is segmented into domain-specific allocations that satisfy local policies while being coordinated to achieve overall optimization. This allows different parts of the network to have tailored resource allocation strategies.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent applies different policies to different domains based on their specific requirements. Each domain can have customized resource allocation priorities (e.g., some domains prioritize reliability, others prioritize resource efficiency). This local quality approach ensures that domain-specific policy requirements are met while maintaining overall network efficiency.

Inventive Principle:

Principle #3Local quality

2Adaptability or versatility

If multiple policies are applied to different domains without considering policy importance, then domain-specific requirements are satisfied, but the degree of policy conformance varies without prioritization

Engineering Contradiction:

Improvedomain-specific policy applicationVSAvoidpolicy conformance priority

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent introduces a policy importance parameter that quantifies the degree of conformance required for each policy. By changing this parameter, the system can dynamically adjust the priority of different policies during resource allocation. This allows the system to satisfy domain-specific requirements while prioritizing critical policies based on their importance values.

AI summary

A resource allocation method includes splitting requirements into split requirements for each subsection of a physical network. The subsections of the physical network each have one of a plurality of policies applied to them. The method includes calculating a resource allocation for each of the subsections based on the split requirements, integrates a result of the allocations to determine a plurality of solutions candidates for resource allocations based on the split requirements, evaluates, for each solution candidate, compliance with the one of the plurality of policies, and selects one of the solution candidates based on the evaluation.
