Deterministic operation of rapid spanning tree protocols for proper propagation of a “cut”

A method for ensuring a proper propagation of a cut within a bridged network, said method comprising the steps of:

• for each bridge within said bridged network,
• entering an X_PROPOSED state upon satisfying a first condition to transit into said X_PROPOSED state;
• and
• entering an X_AGREED state upon satisfying a second condition to transit into said X_AGREED state,
• wherein said first condition and said second condition are both defined to ensure that the X_PROPOSED state is entered before the X_AGREED state.

A network comprising:

• a plurality of bridges which are coupled to one another by links, each bridge configured to ensure propagation of a cut by:
• entering an X_PROPOSED state upon satisfying a first condition to transit into said X_PROPOSED state;
• and
• entering an X_AGREED state upon satisfying a second condition to transit into said X_AGREED state, wherein said first condition and said second condition are both defined to ensure that the X_PROPOSED state is entered before the X_AGREED state.
