Abstract
The objective of this thesis was to carry out a performance evaluation
between UDP and UDP Lite. The UDP measurements were performed in the wireless
802.11b environment using MPEG-4 audiovisual streams and the theoretical
performance analysis were made for the UDP Lite. The transport protocol test
environment, i.e. testbed, was build for performing the measurements in an
equal environment. A software was developed to produce measurement results for
the analysis.
As a result, the performance analysis proved that UDP Lite provides a more
efficient way to transport coded audiovisual content over the error-prone
networks than UDP. The used parameters were the throughput and packet loss at
the transport layer and the jitter between sequential packets. One of the
comparisons was the packet loss probability at different BER values.
The theoretical part of the thesis concentrates on describing the multimedia
streaming architecture, technologies, protocols and standards, which handle
the higher level tasks. The underlying network architecture, which is
constructed of the layered infrastructure for data transportation, is also
covered; including the network access technologies.
