Abstract
A system and method are provided in which communication adapters, which are used for the transfer of message packets from and amongst a plurality of data processing nodes, are provided with internal storage which is used to indicate the status of a particular adapter as a master, as a slave or as a backup up adapter. This information provides the adapters with the ability to be called into service to take over the operations of another adapter in the event of node or adapter failure.
