			***     PLEASE NOTE TIME AND VENUE CHANGES ***


> 		The next joint EEE/COSC Networking Group Seminar will be:
> 
> 
> "Improving TCP Performance in Wired-Wireless Environments "
> 
> Gustavo Da Costa
> M.E. student in Electrical Engineering
> University of Canterbury
> 
> Friday 23 February 2001
> 12:10 pm
> Level 3 Lecture Theatre (Room A309), EEE Building
> 
> While TCP can perform well in the conventional (wired) Internet, the
> fundamental assumptions under which TCP was developed cause dramatic
> performance degradation when a connection goes through a wireless link,
> due to the higher wireless link BER and  user mobility. The increasing
> demand for "Anytime-anywhere" Internet access and the widespread use of
> TCP as the reliable transport protocol in the Internet creates the need
> for modifications to TCP so that its performance is not severely penalised
> by a wireless link, while still providing adequate performance on wired
> links. 
> 
> This seminar will present an overview of the sources of TCP performance
> degradation in wireless environments, as well as the main considerations
> that should be observed when attempting to modify the protocol. Different
> approaches used for performance improvements, their strengths and
> drawbacks will then be briefly discussed. A summary of recommended
> approaches for TCP performance improvement in different situations will
> then be given.
