| Abstract | Real-time broadcasting over Mbone on the Internet has become common over these
past few years. One problem found in this environment is due to the differing time zones in
viewing the broadcasted materials. To overcome the inconveniences caused by the time zone
problem, a scheme to cache the real-time data from the Mbone for subsequently viewing among
members within the same time zone is proposed.
This thesis demonstrates a design of relay station which temporarily stores and
retransmits the real-time data to the users in the same time zone. From the proposed design, all
of the cached data is stored on the hierarchical multi-disk storage from which the
retransmission of the cached data takes place by both scheduled multicasting and on-demand
mode. The multiple retransmission rates will be set according to the capability of the users'
connection lines and their current available bandwidth.
Experiments on a prototype relay station implemented in this study have verified the
functionalities of the proposed design. It has been shown that if high speed disk drives can be
provided at the relay station then high quality of services can be achieved where the final
transmission rate is selected appropriately to accommodate the capacity of the connectivity
from the relay station to the end receiver. However, with low capacity stations, it has been
shown that various adjustments to the buffer sizes could be made to ensure that the broadcast
sessions can be received at the relay station with some data loss. |
