To avoid the need for all the nodes of a network to know the load status of all other nodes and links in the network, the nodes (101....303) are organized in node groups (10, 11, 12, 20, 30). Each group has a master node (104, 124, 113, 201, 301) which is incorporated in a logical higher order group. By recursively grouping the units of each preceding group, a logical hierarchical structure is formed in which the number of units at each level (A, B, C, D), decreases. Each node informs the other nodes of its load status, and each higher level unit also exchanges information with the other units. The recursive, hierarchical structure greatly reduces the amount of load status information exchanged across the network. |
