摘要：Quality of Service (QoS) is regarded as one of the most important factors to improve the performance ofthe network. The QoS can be improved in the Telecommunication Network (TN)by improving the ability to handle thetraffic heterogeneous type and its requirements, which is what this paper tackles. In modern TN, optimizing the routingmechanism improves the QoS significantly because the routing methods orientation is used in the hybrid network,ensures an adaptability of routing process according to the change in system operation conditions, and in theimplementation of the hierarchical management strategy. Applying the routing protocols that are used in practical TNand the required mathematic formulas are deduced and compared with the relative results, taking into consideration thatthe optimized routing processes by developing the appropriate hierarchical-coordination methods. The results show thatthe implementation of the adaptive strategy in accordance with the proposed models allows to increase the networkproductivity by 10-30% and to significantly reduce the possibility of overload which positively is reflected over theguaranteed QoS desired. Moreover, the experimental study of hybrid routing with QoS-support demonstrated thatduring a joint use of various packet switching modes, increases the network performance from 30% (with only thevirtual connect mode) to 80% (with the introduction of the datagram exchange) on average is achieved.
