* This structure refers to one physical device shared among parties (logical devices represented by

* It allows storing information on the common resources in one place and is shared among participants.
* There is only one copy that is constructed by the first participant and destroyed by the last.
* A participant knows it is the first or last by checking the lists of buddies (Rx + Tx).
