One of the critical problems in maritime tactical networks is how to maximize the Quality of Service (QoS) achieved by critical traffic while dealing with mobile and limited-capacity links. As part of a research effort to provide enhanced communications capabilities in a maritime tactical network, a number of traffic-engineering techniques have been investigated using the OPNET discrete-event simulation (DES) tool. In this paper, we describe the model developed to simulate the maritime environment and the impact on network traffic of three traffic-engineering based management services: first, a traffic-monitoring service matches the amount of traffic it produces with its knowledge of the current load of the network; second, a traffic-prioritisation service uses weighted fair queuing (WFQ) to prioritize critical traffic; and finally, an adaptive-routing service uses multi-path labelled switching (MPLS) to divert traffic from overloaded links. The effect of these services on network traffic has been simulated and the results are described in this paper.
