As a promising technology for the future Internet, network virtualization makes it possible to reshape currently ossified network architecture. This paper proposes a limited scale-free model for construction of virtual networks topologies, aiming to reduce network average path length and achieve a simplified virtual network. In the progress of constructing, new links are added into the initial network...
Mobile Edge Computing (MEC) aims to provide mobile and cloud computing capabilities within the radio access network, and emphasizes the openness of the internet which can transfer the real-time radio network information into context-related services. In this article, we research the state-of-the-art technology of mobile and cloud convergence, then propose WiCloud, a MEC platform, which integrates...
In the last two years, ETSI's NFV Management and Orchestration working group has defined the NFV reference architecture. Network Function Virtualization (NFV) intends to decouple the network function from dedicated network appliance through virtualization technologies. As security is an important issue in the context of NFV environments, but the ETSI NFV architecture didn't involve much about security...
In order to reduce cost and complexity, fiber-wireless (FiWi) networks emerge, combining the huge amount of available bandwidth of fiber networks and the flexibility, mobility of wireless networks. However, there is still a long way to go before taking fiber and wireless systems as fully integrated networks. In this paper, we propose a network virtualization based seamless networking scheme for FiWi...
The fiber-wireless (FiWi) access network combines plenty of available bandwidth of the fiber network and the ubiquity and mobility of the wireless network, with the purpose to reduce their cost and complexity. The FiWi network is thought by many as a very promising architecture for the future network. From the standpoint of the Internet service provider (ISP), though the FiWi network has the advantages...
