Recent developments show a progressing convergence of networks, services, and applications, which results in the necessity for new approaches to provide a ubiquitous experience on converged networks for specialized high data-rate services. A fundamental diversifying attribute for the future physical network convergence paradigm is pressing. In this paper, we make researches on converged resource reconfiguration model of substrate physical network based on hardware virtualization and provide a service oriented network architecture as a network convergence primitive. Based on the idea of hardware virtualization which is performed by platform deformation and component processing with reconfiguration (here, they are realized as reconfigurable routers (RR)), the substrate converged network, which inter-connects various access networks by reconfigurable routers, could be mapped into multiplex service oriented logical networks, supports dynamic reconfiguration due to diversified quality of services under heterogeneous environment, and therefore provides more flexible and high- speed multiple services. In addition, to demonstrate the generality of our model, we provide a prototype of reconfigurable router. The design, implementation and task scheduling as well as both hardware and software reconfiguration process of reconfigurable router are discussed in detail. Our evaluation shows that reconfigurable router is transparent for upper service-providing networks and results in little performance impact on the service delivery when both hardware and software reconfiguration are used.
