Nas redes de modo de transferência assíncrona (ATM), o congestionamento pode ser causado por flutuações estatísticas imprevisíveis dos fluxos de tráfego e condições de falha na rede. Se ocorrer congestionamento, o desempenho da rede para a conexão já estabelecida diminuirá. As redes ATM usam mecanismos preventivos de controle de congestionamento, como Controle de Parâmetros de Uso (UPC) e Controle de Admissão de Conexão (CAC) para evitar condições de congestionamento. Sabendo que muitas fontes em redes ATM possuem fluxo de tráfego variável com diferentes características de QoS, funções de gerenciamento de tráfego tornam-se necessárias para controlar os fluxos de tráfego dentro da rede. Ao utilizar os procedimentos de sinalização na fase de configuração da chamada, a rede e a fonte chegam a um acordo para alguns parâmetros característicos do tráfego. Se a fonte violar os parâmetros de tráfego, a probabilidade de congestionamento aumenta. Portanto, a rede deve controlar os fluxos de tráfego de origem e detectar bem as células violadoras. Portanto, a detecção rápida de qualquer fonte de infração é uma das características mais importantes de um bom policial de trânsito. Neste artigo propomos um policial de trânsito fuzzy com alta habilidade na detecção de fontes infratoras. Nosso controlador fuzzy proposto tem duas entradas, a taxa média de célula passada estimada e o estado atual do contador. Se a saída do controlador fuzzy for 1, então a célula de entrada é detectada como célula violadora, caso contrário é uma célula não violadora. Os resultados de simulação obtidos de duas fontes de tráfego mostram que o policial de trânsito proposto tem melhor seletividade do que o balde furado convencional. Observa-se que nosso policial de trânsito proposto possui melhor capacidade de controle da taxa média de células, controle da taxa de pico das células e controle da duração do burst. Além disso, observa-se que o policial de trânsito proposto supera o balde furado convencional principalmente quando o comportamento dinâmico é considerado.

Abstract: In Asynchronous Transfer Mode (ATM) networks, congestion can be caused by unpredictable statistical fluctuations of traffic flows and fault conditions within the network. If congestion happens, then the network performance for the already established connection will decrease. ATM networks use the preventive congestion control mechanisms such as Usage Parameter Control (UPC) and Connection Admission Control (CAC) to avoid congested conditions. Knowing that many sources in ATM networks have variable traffic stream with different QoS characteristics, traffic management functions become necessary to control the traffic flows within the network. By using the signaling procedures at the call setup phase, the network and source reach an agreement for some traffic characteristic parameters. If the source violates the traffic parameters, then the probability of congestion increases. So the network must control the source traffic streams and detect well the violating cells. Therefore, fast detection of any violating source is one of the most important characteristics of a good traffic policer. In this paper we propose a fuzzy traffic policer with high ability in detection of violating sources. Our proposed fuzzy controller has two inputs, estimated passed mean cell rate and the current state of the counter. If the output of fuzzy controller is 1, then the input cell is detected as violating cell, otherwise it is a non-violating cell. Simulation results obtained from two traffic sources, show that the proposed traffic policer has better selectivity than the conventional leaky bucket. It is observed that our proposed traffic policer has better ability for mean cell rate control, peak cell rate control and burst duration control. Furthermore, it is observed that the proposed traffic policer outperforms the conventional leaky bucket specially when the dynamic behavior is considered.
