Network Mapping and Protocol Analysers

["Talisker" <offthecuff () lineone net>]

Hi
I'm looking for a protocol analyser and some good network mapping software,
anyone got any favorites?  I apologise for the text below reading like an
advert in a personals column, though GSOH optional.

Protocol Analyser
Must have a good  range of covered protocols, session reassembly and replay

What other nice features do people make good use of?  I do like different
colors for different protocols

Network Mapping
Looking for a fast tool with minimal bandwidth consumption, suited to
mapping remote networks over thin low bandwidth pipes. Capable of
identifying hosts etc.  Needs to have a good visualisation package

Any help in narrowing down the field would be greatly appreciated
