So, for the moment time is not integrated in CI, but what if the cunning way
round? I want to compare some different configuration scenarios so couldn’t I
do it by taking real time measurements through System.nanoTime()? Of course
those measurements will include the time required from Ptolemy director but
since I am interested in comparative measurements the Ptolemy factor will be
–partially- excluded. Isn’t that correct?
For instance in the first scenario in the attached model packets leave IPInput,
then are pushed to the CMM (stands for configuration management module and is
responsible for installing new protocols to the terminal dynamically) and from
there are pushed to the MobilityProtocol actor (which implements mobility
protocols such as Mobile IP). In the second scenario the CMM is bypassed and
Mobility Protocol packets go directly to the MobilityProtocol actor. Can I
obtain reliable results for comparing average packet processing time between
the two scenarios if I employ packet timestamps through the System.nanoTime()?
