Service-Oriented Architecture for Command and Control Systems with Dynamic Reconfiguration

摘要

Command and Control (C2) systems are evolving as warfighting is changing. Modern warfighting needs a dynamic, adaptable and agile force supported by rapidly changing technology. Three important C2 system characteristics are: survivability, rapid development and evaluation, and interoperability. This paper proposes a Service-Oriented Architecture with Dynamic Reconfiguration (SOADR) for the DoD enterprise C2 system. The proposed SOADR is an extension of the existing Web Services (WS) architecture popularized by Microsoft's NET platform. In addition, the proposed SOADR includes a framework for the dynamic reconfiguration of services thus the C2 system can continue to operate in spite of attacks or service malfunction. With the dynamic reconfiguration framework, individual service can be added, removed, and replaced at runtime without interruption of the system operations. The dynamic reconfiguration policy is governed by the C2 policies that may be obtained through the real-time COIs at runtime based on the information collected by situation-aware monitoring agents. The services are specified with scenario/ACDATE model and policies are specified using a formal specification language PSEL. A variety of service constraints such as survivability, security and performance can be verified and enforced at runtime through the proposed SOADR dynamic reconfiguration framework. This framework is also based on the standard protocols.
