it took me a little bit longer, but you can find new features
description below. Please let me know your opinion and if there are any
issues with adding these features to the NDT.
1. Configurable Time-Based Test
Configurable test duration for each direction (upstream and downstream)
will be provisioned at the test server side. The existing revision of
NDT throughput test runs an upstream and downstream test both for
duration of 10 seconds. The new duration will be negotiated at the
beginning of each test.
2. Throughput snapshots
In addition once the duration, X, of the complete test is decided, the
test receiver (test server for the upstream test or user PC for the
download test) will measure throughput snapshots at each Y second
interval where Y < X. For example, if X = 30sec and Y = 5 sec, then the
throughput is measured at each 5 second increment during the 30 second
test. The value measured at each 5 second increment is collected and
reported at the test server. The throughput snapshots functionality will
be negotiated at the beginning of each test.
3. Multi-Threaded Test
The capability for the server to use multiple parallel TCP connections
(i.e. multi-threading) for running the NDT tests on both the server and
client sides. The existing NDT throughput test performs using a single
TCP connection for each test direction. When multiple threads are used
then the corresponding number of TCP ports should be used (one for each
thread) during the testing phase. The number of threads will be
negotiated at the beginning of each test.
