Two network-virtualization architectures, namely, network segmentation and network paging, were investigated. They are analogical to two memory-virtualization architectures: segmentation and paging. Network paging, which is relatively new and is based on a type of Network-Address Translation (NAT), is focused on. This architecture requires smaller packet size and has several more advantages over the conventional architecture (i.e., network segmentation). Intranet- and extranet-type communication methods based on this architecture are described. An address translators is placed at each edge router in the WAN and used to evaluate client-server communication under wide-area Virtual-Machine (VM) live migration as a case of extranet-type communication.
