Could you explore one thing regarding NS2? The thing is, how you will explain the EVENT (::expire(e)) when you think it in microprocessors instruction-pointer level?
Is putting an event after certain amount of delay is setting an interrupt after certain amount of delay? And the instruction pointer jumps to the ::expire (*e) routine. pls discuss. --- On Sat, 3/6/10, Teerawat Issariyakul <teera...@ece.ubc.ca> wrote: > From: Teerawat Issariyakul <teera...@ece.ubc.ca> > Subject: Re: [ns] Implementing a new protocol in NS2 > To: deeptisabnani.i...@pec.edu.in, ns-users@ISI.EDU > Date: Saturday, March 6, 2010, 9:24 AM > > > Hi, > > I don't mean to discourage you.
