Aligning the Tactical GIG Server Hierarchy with HAIPE Dynamic Discovery Protocol

This paper explains how the tactical Global Information Grid server hierarchy approach needs to be aligned with the High Assurance Internet Protocol Encryption tunnel formations. With the commercial Internet, server reachability is based on the Internet Protocol routes, With the strategic networks of the Global Information Grid (e.g., the Defense Information Systems Network), extending continental US services to a teleport is straight forward through the encryption tunnels over static topology, With the tactical Global Information Grid, the encrypted core with dynamic links should lead us to select server locations based on how encryption tunnels are formed. This paper ties server locations to the dynamic discovery protocol of the High Assurance Internet Protocol Encryption such that information dissemination and computing resources can be optimized based on encryption tunnel formation regardless of the underlying topology. We show with analysis and simulation results that compared to leaving services centralized at the teleport, creating hierarchical servers and aligning server locations with encryption tunnel formation, results in better utilization of the network core resources, and improvements in client/server activities, both in terms of message download time and reliability (availability of information to the end user).
