Hi
Sorry for the cross-post, I would believe that it is best to reply to tsv-area
only.
I have previously asked people regarding the support of ECN especially for UDP
flows.. There seems to be a lot of uncertanities around this and in general it
is difficult to get any clear view (if there is
Ingemar,
This particular response may be best for the ICCRG list and its
research view of things, but would it be possible to accomplish some
of what you want to do directly or indirectly through PlanetLab? I
don't recall the connectivity requirements and layout for PlanetLab,
but to avo
Hi Ingmar,
I found that one could do some quite useful tests using (on Linux)
traceroute -t hostname. Linux machines seem to reflect the TOS
byte contents even in ICMP error responses and ICMP echos. Though DSCP
bits are usually reset the the ECN bits are more resilient... Since
traceroute uses U

modified ToS field does not stick, it could be some Windows specific feature
that simply clears the ToS field. I will try some traceroute

Hi
I tried the netsh command but still it does not seem to work.
The problem is also that the test app seems to do a SYN with ECE and CWD set,
this is correct, according to RFC3168 the server should respond a SYN-ACK with
ECE, this does not happen however, still the test app marks the test as
