    摘要: The present invention deals with the capability of high speed network nodes to establish new connections by preempting existing ones when insufficient bandwidth is available in the loaded network. More particularly, it discloses the arrangement of numerous preemption priorities in a limited number of groups and the definition of a median priority level within each group. This median, stored in the topology database of each node of the network allows a better bandwidth utilization per group while consuming very little memory space and generating very low traffic overhead.

    摘要: A spanning tree organized architecture within a data communication network including a number of nodes interconnected by bi-directionnal links, wherein each said node is provided with means for dynamically setting and storing within the node a full topology database including full parent node relationship references. The system is also provided with means for fast path determination and fast spanning tree recovery, based on said topology databases contents.
