Abstract(s)
Um Internet Service Provider (ISP) tem a seu cargo a gestão de redes compostas por milhares de clientes, onde é necessário haver um controlo rígido da largura de banda e evitar o congestionamento da mesma. Para isso os ISPs precisam de sistemas capazes de analisar os dados de tráfego e atribuir a qualidade de serviço (QoS) adequada com base nesses dados.
A NOS Madeira é o ISP líder na ilha da Madeira, com milhares de clientes por toda a Região. O sistema de controlo de largura de banda existente nesta empresa era obsoleto e levou à necessidade da criação de um novo sistema de controlo de largura de banda.
Este novo sistema, denominado IP Network Usage Accounting, é composto por três subsistemas: IP Mapping System, Accounting System e Policy Server System. Este relatório, fala sobre o desenho, a implementação e testes do primeiro subsistema, IP Mapping System.
O IP Mapping System é responsável por realizar a recolha de dados de tráfego realizado pelos clientes da NOS Madeira e a fornecê-los ao segundo subsistema, (Accounting System). Este, por sua vez, realiza uma análise desses mesmos dados e envia os resultados ao terceiro subsistema (Policy Server System) que aplica o QoS correspondente a cada IP dos clientes.
An Internet Service Provider (ISP) is responsible for the management of networks made up of thousands of customers, where there must be strict control of bandwidth and avoid congestion of it. For that ISPs need systems capable of analyzing traffic data and assign the Quality of Service (QoS) suitable in reliance thereon. NOS Madeira is the leading ISP in Madeira, with thousands of customers throughout the region. The existing bandwidth control system in this company was obsolete and led to the need to create a new bandwidth control system. This new system, called IP Network Usage Accounting, consists of three subsystems: IP Mapping System, Accounting System and Policy Server System. This report talks about the design, implementation and testing of the first subsystem, IP Mapping System. The IP Mapping System is responsible for performing the collection of traffic data held by customers of NOS Madeira and provide them to the second subsystem (Accounting System). This, in turn, performs an analysis of these data and sends the results to the third subsystem (Policy Server System) applying QoS corresponding to each of the clients IP.
