New advances in future network technologies

Nowadays, Internet has became an indispensable part of our daily life. The network keeps expanding in scales, and the network technologies develop rapidly. From the network architecture to the network application, new technologies emerge constantly. For example, Software Defined Networking (SDN) introduces the programmability of network to achieve more flexible network management. Device-to-device (D2D) communication provides the promising solutions for social applications and content sharing applications in mobile network. Cloud computing and fog computing make it possible to maximize the utilization of network resources. This special issue is intended to introduce some new advances in the above future network technologies, in which eight high-quality papers are presented. There are three papers about SDN including the synchronization of multidomain controllers, the placement of SDN controller, and the traffic scheduling in SDN. Three papers focus on cloud computing, whose topics include the IaaS cloud broker, the fog computing, and the architecture of virtual machine storage. Other two papers are about D2D network and multicast network, respectively. The general objective of this special issue is to show the state-of-the-art in future network technologies and to point out the directions of the research on future network.
