Hi Christian I you may want to look at the iccrg archive for a discussion on the issues with too high packet rate. I posted some very similar questions ~a month ago http://oakham.cs.ucl.ac.uk/pipermail/iccrg/2010-September/000847.html Regards /Ingemar > -----Original Message----- > From: dccp-bounces@xxxxxxxx [mailto:dccp-bounces@xxxxxxxx] On > Behalf Of Christian Hoene > Sent: den 28 oktober 2010 10:32 > To: dccp@xxxxxxxx > Subject: Re: Sending packets out of schedule? > > Hi, > > I forgot one question.
