| Popis: | 87 In recent years, the number of Internet people grows rapidly. Internet applications are ranging from non-real time data services to real-time audio and video service, which need different quality of service (QoS) requirements. Asynchronous transfer mode (ATM) has been proposed as one of the techniques to integrate diverse application services for high speed networks. Because of diverse traffic sources and associated QoSs, an ATM network requires a sophisticated and real-time traffic controller to guarantee QoSs for existing calls and to achieve high system utilization. Recently, intelligent techniques (e.g. neural network, fuzzy logic) have been widely applied to deal with traffic control related problems in ATM networks. Research results showed that intelligent techniques had better performance than conventional schemes. In this thesis, we propose an intelligent traffic controller (ITC) with multiple QoSs including cell loss ratio (CLR) and cell delay variation (CDV). The ITC mainly consists of connection admission control (CAC) and congestion control (CC). In addition, we propose an on-line learning scheme to improve robustness of the ITC. Due to providing multiple QoSs and robustness, the ITC can support all existing network applications as well as those with yet unknown characteristic that would emerge in future. |
