Companies nowadays are approaching towards an all IP paradigm by subscribing to different access technology links from several service providers for reliability, redundancy and availability while providing good Quality of Service (QoS). A framework for rule-based converged hybrid network manage- ment in multihoming environment is presented. Diversity and dimensionality of the platform's service, control, transport and access planes along with multiple objectives over the platform has led us to use Multi Criteria Decision Making (MCDM) technique. A simple use-case involving the dynamic decision-based routing at private-public network border is presented to validate the proposed solution. The decision engine takes multiple criteria into account while computing the routing decisions (attributes from context of the request, platforms latest conditional parameters, business objectives of the company etc.). The system supports outsourcing and provisioning decision computation and enforcement modes. The system gives higher throughput and lower call dropping probability with an add-on susceptible delay offering good QoS.
