The obvious one missing from your list is the Emulab NS file (based on
NS-2), which in addition to describing network topologies, can also
describe software to distribute, programs to run, packet traces to
gather, etc. and lets you script all this stuff as well. Some
documentation:
http://users.emulab.net/trac/emulab/wiki/nscommands
http://users.emulab.net/trac/emulab/wiki/AdvancedExample
There's also the "Expermenter's Workbench" on Emulab which extends the
above with notions like formal parameters to experiments, a more
complicated experiment structure (for example, breaking up experiments
into potentially multiple "runs"), as well as adding a bunch of other
abstractions:
