Distributed interplanetary Delay/Disruption Tolerant Network (DTN) Monitor and Control system

The main purpose of Distributed interplanetary Delay Tolerant Network Monitor and Control System as a DTN system network management implementation in JPL is defined to provide methods and tools that can monitor the DTN operation status, detect and resolve DTN operation failures in some automated style while either space network or some heterogeneous network is infused with DTN capability. In this paper, “DTN Monitor and Control system in Deep Space Network (DSN)” exemplifies a case how DTN Monitor and Control system can be adapted into a space network as it is DTN enabled. Also a “DTN Status Diagnose and Treatment Creator” tool is devised to provide a platform for network operator to compose failure treatment methods according to the received DTN BSR (bundle status report), DTN implementation specific log message and the network specifically produced monitor and control data. This innovative interplanetary DTN Monitor and Control system was created and installed in the mission administrative node as a multi-tiered internet-based web application to support DTN system by monitoring the data delivery and analyzing the delivery statistics from ION (Interplanetary Overlay Network), JPL originally implemented DTN or other DTN implementation. This monitor and control system includes modules related to the DTN bundles status report receiving, health monitoring, DTN operation failure diagnosing, failure treatment composing and failure treatment to GUI conversion. Moreover, a GUI system is designed to provide visual interfaces to display the operation status and DTN topology lively, query the DTN status stored in the database, and guide the designated user to fix the DTN failure.
