Abstract
As part of a research effort to provide enhanced communications capabilities in a maritime tactical network, a Policy-Based Traffic Management System was developed to dynamically control link usage and perform end-to-end QoS. A desirable management service in the maritime network is end-to-end guaranteed QoS for critical application flows. This type of service is most commonly useful for real time applications (such as VOIP or video), but can also be used for critical data transfers (such as a specific image transfer or chat session). By entering a service request, an operator can specify the application flow to be considered, the desirable treatment (currently in terms of bandwidth only), as well as any other pertinent information including the priority of the request. A policy-based resource reservation service has been developed that guarantees bandwidth for an application flow by per-hop admission control. This document describes the resource reservation service (RRS) including the design decisions and the algorithms developed to support it. The RRS is organized around a main admission control algorithm that consists of four phases. In the first phase, global link information is used to generate potential routes between the source and destination of the requesting flow. The second phase probes the potential routes to determine if sufficient resources are available on all links. In the third phase, an acceptable path is selected and committed. Finally in the fourth phase t
