Abstract

"PROCESSO E DISPOSITIVO DE OTIMIZAçãO DIN MICA DA QUALIDADE DE SERVIçO EM UMA REDE DE TRANSMISSãO DE DADOS". A presente invenção se refere a um processo de otimização dinâmica da qualidade de serviço em uma rede de transmissão de dados (2) em modo pacote, a dita rede (2) possuindo uma pluralidade de fontes Si e uma pluralidade de destinações Di ligadas a uma rede de trânsito (4) via uma pluralidade de redes de acesso (6), cada fonte sendo suscetível de enviar uma vazão máxima L~ max,s,x~, e cada destinação sendo suscetível de receber uma vazão máxima L~ max,x,d~, as ditas fontes possuindo cada uma delas um meio de classificação (8) e de controle (10) da vazão de dados emitidos, processo caracterizado pelo fato de que ele compreende as seguintes etapas: a) medir o retardo absoluto de transferência a instabilidade, a vazão dos ditos dados trocados e as perdas entre cada fonte S e cada destinação D, e efetuar as sub-etapas seguintes em função das medições obtidas nessa etapa a: a1) para cada destinação D, distribuir a vazão máxima L~ max,x,d~ entre as diferentes fontes; a2) para cada destinação D, determinar dinamicamente o limite do ponto de congestão da rede de acesso (6) que otimiza a vazão máxima L~ max,x,d~; a3) para cada fonte S, determinar dinamicamente o limite do ponto de congestão da rede de acesso (6) que otimiza a vazão máxima global L~max,s,x~ e a vazão máxima na direção de cada destinação L~ max,s,d~; a4) para cada fonte S, determinar o efeito da congestão da rede de trânsito (4); e b) comandar os meios de classificação (8) e de controle (10) de vazão em função dos resultados das sub-etapas a1, a2, a3 e a4.
