Management of QoS Provisioning Architectures

摘要

Provisioning of QoS guaranteed services in current installed networks is an important issue, but only the deployment of QoS services is not enough to guarantee the success of those services: QoS management also must be provided. Nowadays, police-based management addresses this need, but such management is not enough either. Network managers often deal with QoS tasks that cannot be performed using only police-based management. This paper describes six important QoS management related tasks (QoS implantation, operation maintenance, discovery, monitoring, analysis and visualization) and shows solutions that can help managers proceeding with these tasks. Unfortunately, these solutions are independent each other, leading to a scenario where integration is difficult. To solve the lack of integration the QAME (QoS-Aware Management Environment) was developed. QAME provides support to allow the execution of the defined QoS tasks in an integrated fashion.
