Re: Bandwith consumption

Hi Martin,

I'm testing a videoconferencing system and I would like to estimate the
maximum number of active conference rooms at the same time. My question is
about the maximum number of conference room that Fast Ethernet connection
can supply?

I know that Wireshark calculates the bandwidth at IP level and I would know
how much is different from the bandwidth at ethernet level.

> From here http://en.wikipedia.org/wiki/IPv4 I know the fragmentation and
reassembly of IP packets (IP header 20 byte Ethernet header 18 byte MTU 1500
byte)


For example if all IP packets are of the maximum length about 64 kByte, they
are fragmented in 45 ethernet packets of 1500 byte. The overhead is low

I expect little difference between the two bandwidth.

Thank you
