Solution Overview

Problem

Service providers in dynamic networks face challenges in manually monitoring and tracking dynamically changing network capacity, leading to cumbersome and expensive processes, as well as inaccurate reporting and system modifications, which can result in incorrect activation of new services and failure to meet Service Level Agreement (SLA) requirements.

Innovation Solution

A system that includes an auto capacity evaluation component to calculate available network capacity, a service activation component to determine if new services can be activated based on SLA requirements, and a feedback mechanism to update capacity changes, allowing for automatic monitoring and tracking of network topology and capacity, enabling efficient activation or rejection of new services and expansion of network capacity as needed.

AI summary

A capacity aware system that facilitates activation of a new service in a dynamic network is provided. The system calculates the available capacity of the network, at a given time, and determines if sufficient capacity is available for new service activation as per the SLA (Service Level Agreement) requirements. If SLA conditions are satisfied, the system can active a new service and update the network capacity, else, if the conditions are not satisfied the system can provide means to extend network capacity or reject the service. Thus, the system activates a new service only if the specified bandwidth is available and ensures that the SLA being promised to a customer is met.
