A framework of network connectivity management in multi-clouds infrastructure
The network function virtualization (NFV) transformation
is gaining an incredible momentum from mobile
operators as one of the significant solutions to improve the
resource allocation and system scalability in fifth-generation
(5G) networks. However, the ultra-dense deployments in 5G
create high volumes of traffic that pushes the physical and
virtual resources of cloud-based networks to edge limits. Consider
a distributed cloud, replacing the core network with virtual
entities in the form of virtual network functions (VNFs) still
requires efficient integration with various underlying hardware
technologies. Therefore, orchestrating the distribution of load
between cloud geo-datacenters starts by instantiating a virtual
and physical network typologies that connect involved front haul with relevant VNFs. In this article, we provide a framework to manage calls within 5G network clusters for efficient utilization of computational resources and also to prevent unnecessary signaling. We also propose a new scheme to instantiate virtual tunnels for call forwarding between network clusters leading to new logic networks that combine geo-datacenters and fronthaul. To facilitate service chaining in cloud, we propose a new enhanced management and orchestration (E-MANO) architecture that brings network traffic policies from the application layer tothe fronthaul for instant monitoring of available resources. We provide analysis and testbed results in support of our proposals.

Mobile Oriented Future Internet (MOFI)
This Special Issue consists of seven papers that discuss how to enhance mobility management and its associated performance in the mobile-oriented future Internet (MOFI) environment. The first two papers deal with the architectural design and experimentation of mobility management schemes, in which new schemes are proposed and real-world testbed experimentations are performed. The subsequent three papers focus on the use of software-defined networks (SDN) for effective service provisioning in the MOFI environment, together with real-world practices and testbed experimentations. The remaining two papers discuss the network engineering issues in newly emerging mobile networks, such as flying ad-hoc networks (FANET) and connected vehicular networks
