Josh, others,
I am interested in hearing how/if TTM (Test Traffic Measurements) is currently being used in North American networks.
At the moment, there are 8 sites participating in the measurements and a 9th ordered its test-box this morning. The 8 boxes are located in Palo Alto, Denver (2), Chicago, Fermilab (near Chicago), Austin, Washington DC and Ann Arbor. The 9th box will be installed in the Bay area as well. Besides that, 3 big ISP's have shown interest in deploying boxes for 2 different projects, this would involve something between 5 and 15 boxes all over the US.
Practical experiences, gotcha's,
The biggest problem so-far was the installation of the GPS antenna. In order for GPS to work, it requires a view of the sky, preferably from the outside of the building. That is not always possible in the US, with its buildings where windows cannot open and PoP's are frequently located in the basements of buildings. This problem has now been solved. We now support CDMA based clocks units that use the carrier signal from CDMA based cell-phones. These units work inside buildings, everywhere where a cell-phone works. Geographic coverage of the USA is about 99%. Installation costs of these units are 0.
value proposition, support, etc.. would be of interest.
We recently did a user survey of TTM and our customers rated both value for money and support as excellent.
