[ns] time resolution in Gbps bandwidth




Hi,

When I use Gbps as links bandwidth, but I just
found the total delay of a packet is not exactly equal
to the sum of propagation delay and transmission delay
of the packet (I removed the queue delay from links,
so there is no queuing delay introduced).

My way to calculate delay is that received time at
the received substracts the time in time stamp of packet
header.  With Mbps bandwidth, results look reasonable
with the acceptable resolution.

Is that the problem of the resolution of ns scheduler?

Thanks a lot,
Bo Wen
