+This case study concerns the Tree Identify Protocol of the IEEE 1394 High Performance Serial Bus (called ``FireWire'').
+
+These are MDP models, manually constructed from probabilistic timed automaton (PTA) models,
+using the "digital clocks" semantics [KNPS06]. You can also find the PTA models, in the directory ../pta/firewire.
+
+We consider the following probabilistic timed automata models of the root contention part of the 
+tree identify protocol, which are based on probabilistic I/O automata models presented in [SV99].
