Gateway-to-gateway protocol issues in a tactical environment

Winkelmann, C.A.

Due to the nature of the threat in future tactical environments, deployable systems must be survivable, secure, interoperable, reliable, flexible and transportable. The systems architecture that will be necessary to operate in the future tactical environment will be mobile and modular with functions distributed among physically dispersed elements. In this future architecture, local area networks (LANs) will play a vital role. Some of these LANs could be connected together via homogeneous gateways to form an autonomous system. As a deployment expands, these autonomous systems then could be connected via another set of homogeneous gateways to form an internetwork. Due to the nature of the tactical environment, the topology of the internetwork will be dynamically reconfigured. The dynamics of the topology present a challenge to routing algorithms. To assist the routing algorithms in their task, a set of gateway-to-gateway protocols is used to pass routing and connectivity information among gateways.
