Abstract
In a multimedia streaming system,we need jitter-less bandwidth that satisfies playback
rate to transmitmedia data fromsupplying peers. There is a challenge to provide
high quality real-time streaming over wireless network. We have to know the available
resources of each client to provide QoS support. However, when the application
transmits data over wireless network, it is very difficult to know the available bandwidth
due to unstable physical carrier.
In this thesis, we investigate two problems: (1) how to efficiently estimate available
bandwidth and (2) how to efficiently manage bandwidth according to the given
QoS parameters for each connection. We develop a bandwidth management system
to solve these problems. The system is an underlying part of a peer-to-peer media
streaming system. It provides approximate bandwidth information and bandwidth
management service to upper layer QoS management. By managing bandwidth according
to available bandwidth dynamically, a peer-to-peer system can select appropriate
supplying peers dynamically to provide QoS support. It also prevents media
streaming being affected by other network traffic. Thus, high quality playback can be
achieved over wireless network.
