    Software based traffic separation at the access layer
    (Scholastic Scientific Publishing, 2014) Andegelile, Yona; Mtonyole, Nixon
    Access Network is the subscriber part of the telecommunications network or the network connecting the subscribers to the Internet Service Providers (ISP) [1]. In many countries including Tanzania access network is still predominantly made up of the copper cable based or other point to point wireless connections. This has kept the network in large proportions passive, inflexible and relatively unreliable [2]. This traditional network has long been tailored to the services generally provided i.e. voice, leased lines, Internet, corporate data and video conference, sometimes each provided by separate equipment and networks. This paper presents the study on approaches used by ISP in Tanzania to separate traffic in the access network. The paper also presents the effective way of traffic separation, whereby multiple hardware used to separate traffic currently has been replaced with single hardware. The traffic separation technique is based on creating logical links (software based) for each traffic type inside single physical link, providing a differentiated QoS support for each type of traffic according to its individual QoS requirements

    Voice quality analysis for software based traffic separation at the access layer of hierarchical design model
    (Taylor and Francis Ltd, 2014) Mtonyole, Nixon; Andegelile, Yona
    In many countries including Tanzania access network is still predominantly made up of the copper cable or point to point wireless connections. This has kept the network in large proportions passive, inflexible and relatively unreliable. Software based traffic separation at the access layer is a technique that is used to reduce the number of physical links to customer premises. This paper performs quality analysis for voice transmitted through such links (i.e. logical links) and it is observed that there is no major difference as to when dedicated physical links are used.
