The Test Traffic Measurement Service (TTM) was shut down on 1 July 2014. This information is available for historical reference.
This page very briefly describes how you can access the data taken with the test box at your site. The data formats are still preliminary and may chance without notice.
There are two ways to access the data:
Before you can access the data, your machine(s) has to be added to a local configuration file. There is no official procedure for this (yet), for the time being, simply email us the IP address (range) of your machine(s).
A server will be started as soon as the machine starts data-taking. To listen to the server, type:
telnet test-box 9142
where test-box is the name or IP-number of your test-box.
If the test-box is taking data, then you will see something like this appear on your screen, updated about once a second:
RCDP 10 2 188.8.131.52 1197 184.108.40.206 6000 892652515.866538 0.009550 0X107 0X107 892652515
Lines can either start with a 4-letter identifier followed by one or more numbers and a carriage return to terminate it, or by 2 numbers, a fixed IP address (127.127.20.0) and a string. The formats are explained here for the lines starting with a 4 letter identifier and here for the other strings. Data will appear on your screen until you type control-].
If the test-box isn't taking data, then you will see something like:
telnet: Unable to connect to remote host: Connection refused
Lines starting with a four-letter keyword are generated by one of the data-taking processes on the machine. The keyword is followed by an integer indication the number of fields that will follow and 0 or more data fields. Fields are separated by spaces. A new line will be written whenever a data collection process produces output. Currently three keywords have been defined:
Please note that this is a preliminary format and that fields may be dropped or added on short notice.
Lines starting with two numbers and an IP-address (usually 127.127.20.0 or 127.127.31.0) are produced by the GPS receiver. They give the current status of the GPS receiver and are produced about once every 64 seconds. The format depends on the type of receiver that you have:
