Solution Overview

Problem

Network bandwidth oversubscription leads to packet drops and service degradation due to inadequate monitoring of historical and peak utilization times, as existing methods only check utilization at the time of deployment without considering varying peak times throughout the day.

Innovation Solution

A system and method for automated steering of network traffic over a least latency path, utilizing a hardware-based processor and modules such as a service request module, process train module, and connection admission control module to identify and configure the network to steer traffic on the least latency path, while checking against historical maximum bandwidth utilization and generating notifications for threshold exceedance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If bandwidth utilization is checked only at the time of deployment, then the network configuration process is simple and fast, but bandwidth oversubscription occurs leading to packet drops and service degradation

Engineering Contradiction:

Improvenetwork configuration speedVSAvoidservice quality

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The system performs preliminary analysis of historical bandwidth utilization data before admitting new traffic flows. The CAC module queries the performance management system for historical peak utilization data and evaluates whether the network can accommodate additional traffic without oversubscription, preventing service degradation before it occurs.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system establishes a feedback loop where the CAC module continuously monitors historical bandwidth utilization data from the performance management system and uses this information to make admission decisions. This feedback mechanism ensures that new traffic flows are only admitted when they will not cause oversubscription during peak periods.

Inventive Principle:

Principle #23Feedback

2Reliability

If historical maximum bandwidth utilization is monitored and checked, then bandwidth oversubscription is prevented, but the system complexity and data processing requirements increase

Engineering Contradiction:

Improvebandwidth management accuracyVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The performance management system acts as an intermediary that collects, stores, and provides historical bandwidth utilization data to the CAC module. This intermediary component centralizes the complex data collection and analysis functions, keeping the CAC decision-making logic relatively simple while maintaining high reliability through comprehensive historical data analysis.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A system and method perform automated steering of network traffic over a least latency path. A service request module receives traffic parameters from a user, a process train module generates a service identification (ID) in response to a request from the service request module, and a connection admission control module generates a service ticket including the service ID and the traffic parameters, communicates with a network controller to gather information about a network, determines the least latency path through the network from the gathered information, and generates a command in the service ticket. Activation of the command configures the network to steer the traffic flow of communications of the user on the least latency path. The method implements the system.
