Abstract
Abstract Methods, systems and computer program products for controlling scheduling in an ATM node in a network are provided which aggregate connection information for connections to the ATM node to provide a set of aggregate connection information for the ATM node. The set of aggregate connection information is distributed to other ATM nodes in the network and may be used in accepting connections to the ATM network based on the aggregate connection information. Scheduling may be provided by associating a timestamp value in each cell associated with an accepted connection as it is received by the ATM node. Received cells are grouped into a plurality of cell groups in timestamp order based upon characteristics of the cells and cells are selected from each group so as to transmit the cells in earliest deadline first order.
