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.

A shared computing infrastructure includes a plurality of computing engines, applications servers, and computing domains. A broker component executes a method for dynamically allocating the computing engines among the computing domains. The allocation method begins with the step of determining an expected number of computing engines to be allocated to each of the computing domains as a function of a predetermined service policy and a predicted demand for the domain While fewer than the expected number of computing engines has been allocated to each domain, the computing domains are sequentially selecting as a function of predetermined domain priorities. Unallocated computing engines are identified, and the unallocated computing engines are allocated to each selected computing domain according to predetermined selection rules for the domain. During an allocation improvement step, allocations among the computing domains are further adjusted to maximize a fitness statistic computed for the allocations.
