Survivable routing procedures for circuit-switched satellite-terrestrial networks
Abstract
New routing algorithms, designed for the Defense Switched Network, are presented for circuit-switched networks which include both broadcast and point-to-point transmission media. Two classes of routing procedures are examined: (1) mixed-media routing and (2) adaptive mixed-media routing. Procedures from both classes are evaluated using a steady-state network analysis program, and both 20 and 40 node satellite-terrestrial networks. The procedures are compared to a simple modified forward routing algorithm used in AUTOVON and to primary-path only routing. Evaluations were carried out with traffic overload, chaotic offered traffic, and different amounts and types of network damage. The new routing procedures were found to substantially enhance network performance after damage; they improved the service provided to the most poorly served group of users, and they denied the possibility of call completion to the fewest users.
