Abstract
A technique for reducing ATM call blocking is provided that splits wideband connections into multiple low-bandwidth sub-connections and routing them independently through the network. Fragmented network bandwidth is used for supporting calls which are otherwise blocked by conventional routing. A detailed cell-level design for the split scheduling algorithms is provided. A system for implementing splitting without requiring any protocol changes within the network is provided. Such a system modifies the control plane protocols only within the end-stations.
