Abstract: On the network virtualization platform that consists of multiple virtualization nodes (VNodes), multiple slices (virtual networks) can be operated simultaneously while isolated from other slices. Virtual nodes (node slivers) can be connected freely by using virtual links (link slivers) at up to 10-Gbps, and arbitrary protocol, which is not constrained by Ethernet or IP, can be used on the slice. VNodes implement virtual links on IP networks by using GRE tunnels. In addition, by using a network accommodation equipment (NACE, NC) that translates the packet data format to an external format, slices can be connected to external VLAN networks at up to 10-Gbps. This paper describes how such connections are referenced and defined by slice developers and how they are translated and physical communication is realized.
