    Dynamic bandwidth allocation in ATM networks
    (2002) Ashibani, Majdi Ali Atoomi; Mashao, Daniel; Nleya, Bakhe
    This thesis investigates bandwidth allocation methodologies to transport new emerging bursty traffic types in ATM networks. However, existing ATM traffic management solutions are not readily able to handle the inevitable problem of congestion as result of the bursty traffic from the new emerging services. This research basically addresses bandwidth allocation issues for bursty traffic by proposing and exploring the concept of dynamic bandwidth allocation and comparing it to the traditional static bandwidth allocation schemes.

    Supporting real time video over ATM networks
    (2003) Shija, Benedict; Mashao, Daniel; Nleya, Bakhe
    In this project, we propose and evaluate an approach to delimit and tag such independent video slice at the ATM layer for early discard. This involves the use of a tag cell differentiated from the rest of the data by its PTI value and a modified tag switch to facilitate the selective discarding of affected cells within each video slice as opposed to dropping of cells at random from multiple video frames.
