Performance Analysis of Triple play Services for IP Over WiMaX and DSL Networks

Abstract

In telecommunications, Triple Play service is a marketing term for provisioning of two bandwidth-intensive services, high-speed Internet access and television, and a less bandwidth-demanding (but more latency-sensitive) telephone service, over a single broadband connection. In this thesis, a Triple Play system performance over IP network is studied with possible techniques and mechanisms such as DSCP QoS algorithms, IP Multicast, IP Unicast techniques and VLAN mechanism, which are proposed to provide efficient Triple Play network management and improved application. Initial applications presented are entertainment video (video on demand VoD and multicast video IPTV), voice (VoIP), and best-effort data (e.g. web browsing, File sharing /downloading).

The performance of the proposed techniques and mechanisms with different broadband access network that support Triple Play services on the last mile are evaluated with simulation scenarios built using OPNET 14.5. The broadband access network used in the simulation of the proposed scenarios is composed of ADSL network to deliver Triple Play services with scalability at an optimal cost by using (IP DSLAM), and WiMax network to deliver adequate QoS to voice, video and data applications represented with a connectivity of 3.5GHz frequency bands with different radio channels bandwidth and with different path loss and multipath channel models. It explores how technologies differ and how can they be combined to provide a total last-mile access solution at the present time and in the future. Simulation results from the previous networks show that such networks can support Triple Play services including demanding real time services with the required QoS. From the results, ADSL has exhibited behavior that approach the ideal values for the performance metrics of the Triple Play services, while WiMax and wireless network have demonstrated promising behavior within the bounds of the defined metrics.
