WiMAX offers unwired broadband access with high capacity of data transmission for dispersed areas. WiMAX network with high bandwidth and suitable speed of transfer can be considered as a solution for public access. This technology with production in considerable volumes from fixed to portable versions shows notable progress in wireless connectivity. Capability of Quality of Service (QoS) support provides user satisfaction in real-time and interactive services over WiMax networks. This network allows the interconnection of MetroEthernet networks with connection up to 10Gbps. The study herein presented deals with a proposal of an end-to-end Quality of Service (QoS suitable not only for voice and video traffics but also for data traffic). The purpose of this study is to investigate WiMAX network performance over a Metro-Ethernet backhaul. Until the elaboration of this work, as far as we know, there is not a theoretical and practical study of the characteristics of real time traffic in WiMAX interconnecting Metro-Ethernet networks
