ABSTRACT:
Nodes in a datagram network are arranged to route datagrams in dependence on a batch start time parameter contained in the header of datagrams belonging to a batch. A network operator is thus able to offer a service that is connection-oriented at the batch level, without necessarily being connection-oriented at the message level. This is advantageous to the network operator since it allows the packet flow generated by the user to be re-routed during the transmission of the message. The user can arrange those datagrams which are required to be delivered from the network in the same order as they are supplied to the network into batches. In that way, the user is not adversely affected by route changes made by the network operator in order to improve the performance of the datagram network.
