Real-Time Inter-domain routing Disruption Detection Tool (RDDT) is a tool for UNIX operating systems. To detect Inter-domain routing disruptions as AS-level, RDDT is peered with the intended AS to detect disruptions.

RDDT tool save inter-domain routing features and the detected disruptions in plot.txt file located in <anomaly_timestamp> directory. RDADT needs many parameters which can be changed in configuration.txt file. BGP session and message handling are done by Net::BGP v0.16,a Perl module that implementsBGP-4 inter-domain routing protocol. This tool helps ISPs operators to detect BGP anomalies at an early stage.
