Design and implementation of a generic connection management and service level agreement monitoring platform supporting the virtual private network service

In this paper we address the design of a generic and scalable architecture for connection management and SLA (service level agreement) monitoring of VPNs (virtual private networks). Layer-based design ensures that the architecture is independent of the network technology. Use of advanced software techniques such as run time compilation and intelligent agents allow easy integration of new monitoring and routing algorithms. The architecture offers advanced features such as VPN edge device capability matching, XML-based SLS (service level specification) language, load balancing of computational tasks, and programmable components. The architecture is compliant with the TINA (telecommunication information network architecture) recommendations and its implementation is based on CORBA (common object request broker architecture). In addition, a sample VPN setup and monitoring scenario will be detailed
