Dalam rangkaian Mod Pemindahan Asynchronous (ATM), kesesakan boleh disebabkan oleh turun naik statistik yang tidak dapat diramalkan aliran trafik dan keadaan kerosakan dalam rangkaian. Jika kesesakan berlaku, maka prestasi rangkaian untuk sambungan yang telah ditetapkan akan berkurangan. Rangkaian ATM menggunakan mekanisme kawalan kesesakan pencegahan seperti Kawalan Parameter Penggunaan (UPC) dan Kawalan Kemasukan Sambungan (CAC) untuk mengelakkan keadaan sesak. Mengetahui bahawa banyak sumber dalam rangkaian ATM mempunyai aliran trafik berubah-ubah dengan ciri QoS yang berbeza, fungsi pengurusan trafik menjadi perlu untuk mengawal aliran trafik dalam rangkaian. Dengan menggunakan prosedur isyarat pada fasa persediaan panggilan, rangkaian dan sumber mencapai persetujuan untuk beberapa parameter ciri trafik. Jika sumber melanggar parameter trafik, maka kebarangkalian kesesakan meningkat. Jadi rangkaian mesti mengawal aliran trafik sumber dan mengesan dengan baik sel yang melanggar. Oleh itu, pengesanan pantas mana-mana sumber yang melanggar adalah salah satu ciri terpenting seorang polis trafik yang baik. Dalam makalah ini kami mencadangkan polis trafik kabur dengan keupayaan tinggi dalam mengesan sumber yang melanggar. Pengawal kabur kami yang dicadangkan mempunyai dua input, anggaran kadar sel min lulus dan keadaan semasa kaunter. Jika output pengawal kabur ialah 1, maka sel input dikesan sebagai sel yang melanggar, jika tidak ia adalah sel yang tidak melanggar. Hasil simulasi yang diperoleh daripada dua sumber trafik, menunjukkan bahawa polis trafik yang dicadangkan mempunyai selektiviti yang lebih baik daripada baldi bocor konvensional. Adalah diperhatikan bahawa polis trafik kami yang dicadangkan mempunyai keupayaan yang lebih baik untuk kawalan kadar sel purata, kawalan kadar sel puncak dan kawalan tempoh pecah. Tambahan pula, adalah diperhatikan bahawa polis trafik yang dicadangkan mengatasi baldi bocor konvensional terutamanya apabila tingkah laku dinamik dipertimbangkan.

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.
