Hello Martin,

Many thanks for the reply and the help. You've cleared a few of my
queries and I now understand where the LSR value is derived from (Thank
you) and I have made sure that RTCP is captured in both directions (I
attach a capture file as an example) - We just have two more queries
which I hope you don't mind helping us with:

To calculate the delay the formula A-LSR-DLSR is used. A simple drawing
is usually provided in examples

 Sender                receiver
 |                        |
 |  SR: NTP timestamp     |
 | ---------------->      |
 |                        |
 |                        |  DLSR
 |                        | 
 |                        | 
 |  RR:LSR, DLSR          |
A|  <----------------     |
 |                        |
 |                        |                       
 |                        |
 |                        |


This looks very simple and I understand this. My problems are this:

1) This diagram is too simplistic because in reality the packet going
from sender to receiver would be a compound packet (CP1)containing a SR
AND RR (not just a SR as shown here) and the return packet from the
receiver to the sender would also be a compound packet (CP2) with SR and
RR. Therefore given the capture file, would I simply take the LSR and
DLSR values from the receiver report in the second compound packet and
the timestamp on the sender side for the A value? i.e. (ignore the RR in
the CP1 and the SR in CP2?)

2) In this diagram we know who the sender and receiver are, however it
is my understanding that in a two way phone call either party can be the
sender or receiver depending on who's speaking (so really its nothing
got to do with who initiated the call). You will see from the capture
file that phone B (157.190.70.65) sends a RTCP compound packet to phone
A (157.190.74.153)first even though phone A initiated the call.
Therefore at the beginning does this make phone b the sender and phone A
the receiver? And if this is the case must I check the source and
destination fields every time first before carrying out the delay
calculation to figure out who is the sender and who is the receiver?

Many thanks for the advice so far - It is much appreciated,
Aisling.

Aisling,  I've written some answers below prefixed by [Martin].

Hello Martin,

My name is Aisling and I am helping David Grau with his project (his
project as part of an undergraduate degree but this also interests me
as part of my postgraduate degree).

I have read rfc 3550 with particular emphasis on the part detailing
how the round trip time (RTT) should be calculated.  The formula
"A-DLSR-LSR" is provided and an example "46864.500 - 5.250 -
46853.125 = 6.125 seconds" is given. We are working from a tethereal
capture file - This was running on the same pc as one of the
softphones involved in the call but as the two softphones calling
each other are on the same LAN segment we should have captured all
the necessary RTCP sender and receiver reports anyway.I have attached
the sample capture file.

[Martin]  Note that within the same LAN segment you are unlikely to see
any
interesting roundtrip delays.  You can set the RTCP preference 'Minimum
rountrip calculations to report'
to 0 milliseconds.



Myself and David are not clear on a few things:

1) The A field is when the receiver report block is received. Is this
referring to the NTP timestamp? I am struggling to identify this from
the tethereal capture (perhaps the capture format is slightly
non-standard?)and if you could point this out from the attached
capture file we would greatly appreciate it.

[Martin]  'A' seems to be the middle 32 bits from the NTP timestamp,
whose units would be 1/65536th seconds. 
All 3 quantities in the formula you quote are in these units, though
they are converted into seconds to make it easier to read.



2)The LSR field is said to be the middle 32 bits of the NTP timestamp
and the NTP timestamp is made up of the MSW and LSW. So if the
figures are MSW=3350115113 and LSW=493921239 I still fail to
understand why the LSR=3005816176...this is based on the figures from
the attach capture file.

[Martin]  MSW and LSW are being displayed as decimals, it is easier to
look at them as hex.
MSW = 0xC7AEB329,   LSW = 0x0x1D70A3D7

The middle word in this case from this would be 0xB3291D70 = 3005816176

However, remember that the LSR in a frame refers to the timestamp seen
in a message seen in the opposite direction
(i.e. in a received message it refers to the middle-bytes from the time
of a frame you previously sent).



3)the DLSR does appear to be 1 for all captures but as you said this
could be for the reasons that you described before.

[Martin] As in the other example I looked at, there appears to be only
RTP/RTCP in one direction, so these values looke made up / default to
me.
You maybe need to make sure that someone is speaking in both directions
to that RTP and SRs are sent.  No calculation can be done until a SR in
one direction
refers to an SR in the previous direction (by matching its LSR and
having a sensible DLSR filled in).



4)Based on the above points and the attached capture file could you
give an example with figures (from the file) of using A-DLSR-LSR?

[Martin]  Sorry, I don't have ready access to my old capture collection
at the moment.  I realise that the way this calculation is done is a bit
complex.
I notice that RFC 3611 allows non-senders to calculate roundtrip delays,
but I've never seen it used in a real client.

I really do hope this helps you.
Best Regards,
Martin
