Abstract
Maritime at sea networks are particularly difficult to manage due to their dynamic and heterogeneous low-bandwidth environment. Four traffic management services of interest to maritime networks have been identified: access control, traffic prioritization, trunk usage, and resource reservation. The first three of these ensure efficient use of bandwidth and effective exchange of information. The fourth, a policy-based resource reservation protocol, provides a precedence-based guaranteed QoS service to critical traffic flows in mobile networks. The policy-based approach offers techniques to automate network management. It allows operators to dynamically change the behaviour of managed systems in response to evolving operational needs without requiring per device intervention. A service-oriented policy-based network management system has been designed to be distributed, secure, flexible, and support the automation of the four identified traffic management services in a maritime tactical network. This document describes the design and architecture of the policy-based traffic management (PBTM) system and management services developed to provide enhanced communication capabilities in maritime tactical networks. The work described in this report can be seen as a contribution towards an overall maritime network management capability and providing some development input to aid in the formulation of a next generation network management architecture.
