Ring Analysis for Mesh Network Service Feasibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Service providers face challenges in determining whether their network has the capacity to maintain a requested service level, especially in complex mesh network topologies, where multiple links with different capacities are involved, and need to assess both normal and failover modes to ensure service level agreements are met.
Innovation Solution
A computer-implemented method evaluates the utilization of a mesh network by recording and predicting link utilization in both directions, determining the maximum utilization for each ring in both clockwise and counterclockwise directions, and calculating the predicted utilization based on these maxima to assess the network's capacity for new connections and potential failover scenarios.

Engineering Contradiction Analysis
1Reliability
If the service provider evaluates network capacity in complex mesh topologies considering multiple links and failover modes, then the reliability of service level agreement determination is improved, but the complexity of the evaluation process increases
Solution Approach 1:
The patent segments the complex mesh network evaluation into distinct components: identifying multiple paths between endpoints, evaluating primary and secondary paths separately, and assessing link capacities independently. This segmentation allows the system to manage complexity by breaking down the overall evaluation into manageable segments that can be processed systematically
Solution Approach 2:
The patent performs preliminary actions by pre-identifying multiple paths and potential failover routes before actual service deployment. The system proactively evaluates capacity constraints and determines feasibility in advance, allowing service providers to make informed decisions about service level agreements before commitments are made
2Reliability
If the network evaluates multiple paths and failover modes for each connection request, then the reliability of capacity determination is improved, but the time required for evaluation increases
Solution Approach 1:
The system performs preliminary path identification and capacity evaluation before service deployment. By pre-assessing multiple paths and their capacities, the network can quickly determine feasibility without time-consuming evaluations at the moment of service request
Solution Approach 2:
The evaluation process is segmented into independent path evaluations, allowing parallel processing of multiple routes. Each path's capacity and feasibility are assessed separately and independently, enabling simultaneous computation that reduces overall evaluation time

AI summary
A mesh network (such as a mesh Ethernet network) is subdivided into rings. For each ring, a network utilization is assessed in both the clockwise and counter-clockwise directions around the ring. A user requests a particular network service. The network rings that would be utilized by the network service are determined. A maximum utilization of all the network rings utilized by the network service in both clockwise and counter-clockwise is determined. The determined maximum utilization is used to determine the feasibility of provisioning the requested network service.
