A Multi-level Policy Representation for Management Services in Maritime Networks

摘要

A Policy-Based Traffic Management (PBTM) prototype was developed to investigate the effective management of communication resources in a tactical maritime environment. The system design includes a combination of Web Services (WS) and policy-based network management (PBNM) techniques. The paper describes a multi-level XML-based policy representation developed for use in the PBTM prototype. Three levels of policies are defined: the high level, the specification level and the low level. The policy representation for each level is given. Aspects that are particular to the system are also discussed. These aspects include hierarchical policy scopes, a rule engine and conflict resolution mechanisms developed specifically for use in the maritime environment.
