1. A method for assigning link bandwidth to a requesting user in a high speed digital network which interconnects network users through paths including high speed links which interconnect network nodes, said method comprising:

  • establishing pre-defined connection priorities among said users;

    splitting predefined reservable link bandwidth into a nominal bandwidth portion and common bandwidth portion, both of which are assignable to the same connections on a priority basis;

    each of common bandwidth priorities being individually related to a nominal bandwidth priority through a predefined relationship making said common bandwidth priorities lower than any nominal priority,whereby requested link connection bandwidth, whatever be its nominal priority, is preemptable primarily on said common bandwidth portion, thus avoiding the disruption of any already established network connection.
