摘要
Proper allocation of network bandwidth is a crucial issue in rendering certain performance guarantees to meet the growing customer demands. Hence, allocation methodologies must explicitly be carried out for these guarantees to be given as efficiently as possible since the shared resources are limited. This invention presents methods and systems for Dynamic Bandwidth Management (DBM) and Quality of Service (QoS) in packet-based networks. DBM is an algorithm that dynamically adjusts the resource allocation in the IP Access Networks based upon measured QoS at the IP Core Network through an implementation of a Feedback Control Mechanism to manage available core transport bandwidth. Such a Feedback Control Mechanism is capable of maintaining a condition of non-congestion, a sufficient and necessary condition to meet end-to-end QoS requirements in a Next Generation Network (NGN). The emphasis is given on the system implementation of QoS policies for the fair distribution of network resources through a scalable architecture comprising key Resource and Admission Control Functional (RACF) entities, namely: a Network Management System (NMS), a QoS Manager, an Access Controller Manager (ACM), the Access Controllers, and the active probes.
