Para fornecer garantias de QoS para cada conexão, foram propostos algoritmos de escalonamento eficientes, como o WFQ. Esses algoritmos assumem que uma certa quantidade de buffer é alocada para cada conexão para fornecer transmissão de pacotes sem perdas. Esta política de alocação de buffer, entretanto, requer muito espaço de buffer, especialmente quando muitas conexões compartilham um link. Neste artigo propomos o uso de política de compartilhamento parcial de buffer (PBS) combinada com controle de parâmetros de uso (UPC) para gerenciamento eficiente de buffer e controle flexível de QoS em switches ATM. Avaliamos a viabilidade do método proposto resolvendo um modelo de Markov. Mostramos também que usando o método proposto, podemos controlar a taxa de perda celular (CLR) independentemente do atraso. Avaliações numéricas são apresentadas, o que indica que o PBS combinado com o UPC reduz significativamente o tamanho do buffer necessário para satisfazer determinadas taxas de perda celular.

Abstract: To provide QoS guarantees for each connection, efficient scheduling algorithms, such as WFQ, have been proposed. These algorithms assume a certain amount of buffer is allocated for each connection to provide loss free transmission of packets. This buffer allocation policy, however, requires much buffer space especially when many connections are sharing a link. In this paper we propose the use of partial buffer sharing (PBS) policy combined with usage parameter control (UPC) for efficient buffer management and flexible QoS control in ATM switches. We evaluate the feasibility of the proposed method by solving a Markov model. We also show that using the proposed method, we can control the cell loss ratio (CLR) independently of the delay. Numerical evaluations are presented, which indicates the PBS combined with UPC significantly reduces the buffer size required to satisfy given cell loss ratios.
