Abstract:
A method in a network switching system having multiple switching units controlled by respective host processing units, the method comprising:generating a data frame by a first of the host processing units, configured as a master unit, by including a destination address of a selected one of the switching units controlled by a corresponding selected one of the other host processing units; outputting the data frame from the master unit to the corresponding switching unit controlled by the master unit; transferring the data frame from the switching unit having received the data frame from the master unit to the selected one switching unit via a backbone link; and forwarding the data frame from the selected one switching unit to the corresponding selected one other host processing unit, for execution of a processing operation specified in the data frame, based on the selected one switching unit detecting the destination address matching an assigned address of the selected one switching unit.
