In this paper, we present gAUDIT, a novel group communication
middleware for auditing in request-response manner. With gAUDIT, an
auditor is able to implement reliable request-response communication for
a group of respondents. But, relying on transport layer retransmission
only will not guarantee the delivery of responses, e.g. if respondent
applications are allowed to operate unreliable, application layer
retransmissions are unavoidable. Additionally, a request-response
capable group communication middleware must be able to handle changes in
the composition of the group of respondents during an ongoing
request-response transaction. gAUDIT is based on application
layer retransmission and handling of group members during an ongoing
request-response transaction. In this paper we describe the gAUDIT
design and use cases. Furthermore, we present a prototypical
implementation and evaluation results.
