Re: Publish or (gulp) Perish

One of the downsides of peer reviewed journals is that it takes an awfully long time from submission to publication - 
typically a minimum of a year.  In a quick moving area like network operations this can be especially problematic.  

One great intermediary to this are pre-print archives, especially the Arxiv archive run jointly between Cornell and Los 
Alamos - http://arxiv.org/ .  They have a big computer science section with lots of good stuff.  Also as far as 
journals the new Internet Mathematics is good if a bit more academically geared than operational.
