SDN Resource Quota Management for Dynamic Network Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing Software-Defined Networking (SDN) technology fixes resource allocation to each Network Service Provider (NSP), leading to insufficient resource sharing and inefficient use of network resources.
Innovation Solution
A resource management device that converts total network resources into a standardized value, assigns these values to each communication service type, and dynamically allocates requested resources based on a reference rate, allowing for sharing between NSPs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the SDN controller fixedly assigns resources in the network to each NSP, then each NSP can provide communication services using assigned resources, but the resources in the network are not shared between NSPs and resource use efficiency is insufficient
Solution Approach 1:
The patent implements dynamic resource allocation by introducing a resource quota management mechanism where the SDN controller converts physical network resources into standardized resource quota units (RQUs), assigns quotas to NSPs based on service types, and dynamically allocates resources within the quota limits. This allows resources to be flexibly shared among multiple NSPs while maintaining efficient utilization through real-time monitoring and adjustment.
2Productivity
If resources are dynamically shared between NSPs, then resource use efficiency improves, but resource management complexity increases
Solution Approach 1:
The patent simplifies resource management by changing the parameter representation of resources from diverse physical units (bandwidth, storage, computing power) to a unified standardized parameter (RQU). This parameter transformation enables the SDN controller to manage heterogeneous resources through a single metric, reducing management complexity while enabling dynamic allocation and sharing across multiple NSPs.
3Ease of operation
If fixed resource assignment is used, then resource management is simple, but resource equity among NSPs cannot be maintained when consumption varies
Solution Approach 1:
The patent implements a feedback mechanism where the SDN controller continuously monitors resource consumption by each NSP against their assigned quotas, dynamically adjusts allocations based on actual usage patterns and service priorities, and enforces quota limits to prevent excessive consumption. This feedback loop maintains resource equity among NSPs while preserving management simplicity through automated control.

AI summary
A resource management device provides a communication service in a network in response to a service request. The resource management device includes a processor. The processor executes a process. The process includes converting a total resource amount in the network into a first value. The process includes assigning a second value to each type of the communication service from the first value. The process includes second converting a resource requesting amount of the service request into a third value. The process includes setting, determining that the third value is equal to or less than the second value that is assigned to the type of the communication service of the service request, a communication service associated with the service request for a communication device on the network.
