要約: Virtualization nodes, i.e., physical nodes with network virtualization functions, contain computational and networking components. Virtualization nodes called “VNodes” enabled mutually independent evolution of computational component called programmer and networking component called redirector. However, no methodology for this evolution has been available. Accordingly, a method for evolving programmer and redirector and developing new types of virtualized networking and/or computational functions in two steps is proposed. The first step is to develop a new function without updating the original VNode, which continues services to existing slices, using a proposed plug-in architecture. This architecture defines predefined interfaces called open VNode plug-in interfaces (OVPIs), which connect a data and a control plug-ins to a VNode. The second step is to merge the completed plug-ins into the original programmer or redirector. A prototype implementation of the above plug-in architecture was developed, tested, and evaluated. The prototype extends the redirector by adding new types of virtual links and new types of network accommodation. Estimated throughputs of a VLAN-based network accommodation and a VLAN-based virtual link using network processors are close to a wire rate of 10 Gbps.
