ADNS IPv6 Transition Architecture and Analysis

The Open Shortest Path First (OSPF) routing overheads were estimated for a 300-ship Navy network architecture, using both analytical methods and simulations on OPNET. In the modeling and simulation effort, a fine-grained analysis was conducted on simulated Cipher Text (CT) and Plain Text (PT) networks to quantify the bandwidth overheads for both IPv4 and IPv6 routing protocols. Various OSPF configurations and parameter settings were also simulated to compare the protocol overheads on the tactical data links. Based on the results of this study, this effort developed recommendations for an efficient IPv6 transition architecture to integrate resource-constrained SATCOM links and legacy networking devices with low bandwidth, high delay and high bit rate error. The results of this research effort provide insights for implementing IPv6 over resource-constrained networks to take full advantage of the next generation networking protocol.
