“…The application plane consists of the network applications (e.g., monitoring and security) and communicates with the control plane through the northbound interface. The control plane consists of the SDN controllers (e.g., Open Network Operating System (ONOS) [14] and OpenDayLight [15]) which govern the network devices. The devices are resided in the data plane.…”

Achieving the fifth-generation (5G) vision will introduce new technology innovations and substantial changes in delivering cutting-edge applications and services in current mobile and cellular networks. The Cloud Radio Access Network (C-RAN) concept emerged as one of the most compelling architectures to meet the requirements of the 5G vision. In essence, C-RAN provides an advanced mobile network architecture which can leverage challenging features such as network resource slicing, statistical multiplexing, energy efficiency, and high capacity. The realization of C-RAN is achieved by innovative technologies such as the software-defined networking (SDN) and the network function virtualization (NFV). While SDN technology brings the separation of the control and data planes in the playground, supporting thus advanced traffic engineering techniques such as load balancing, the NFV concept offers high flexibility by allowing network resource sharing in a dynamic way. Although SDN and NFV have many advantages, a number of challenges have to be addressed before the commercial deployment of 5G implementation. In addition, C-RAN introduces a new layer in the mobile network, denoted as the fronthaul, which is adopted from the recent research efforts in the fiber-wireless (Fi-Wi) paradigm. As the fronthaul defines a link between a baseband unit (BBU) and a remote radio unit (RRU), various technologies can be used for this purpose such as optical fibers and millimeter-wave (mm-wave) radios. In this way, several challenges are highlighted which depend on the technology used. In the light of the aforementioned remarks, this paper compiles a list of challenges and open issues of the emerging technologies that realize the C-RAN concept. Moreover, comparative insights between the current and future state of the C-RAN concept are discussed. Trends and advances of those technologies are also examined towards shedding light on the proliferation of 5G through the C-RAN concept.

“…In fact, the dynamic nature of spontaneous networks (if compared with traditional datacenters) prevents from the adoption of a unique truly centralized MANET SDN controller in charge of monitoring and managing hundreds or thousands of nodes. Each distributed MANET SDN controller has the primarily goal of enforcing QoS in its spontaneous island, i.e., a subset of nodes residing at relatively small multi-hop distance and sharing common interests (thus, with a relevant difference if compared with Open Network Operating System-ONOS [54], where a logically centralized SDN controller is distributed mainly to increase scalability and fault tolerance). Moreover, distributed SDN controllers of neighbor spontaneous islands eventually coordinate one each other to also support (as a secondary goal) QoS of inter-island traffic flows, generated by sender/receiver nodes residing in different spontaneous islands (additional details in [7]).…”

Traditionally, mobile ad hoc networks (MANET) and hybrid optical-wireless networks, also known as fiber-wireless (FiWi), have been considered disjointly and independently, with no synergic management solutions. The former has primarily focused on dispatching packets among mobile nodes in infrastructure-less and very dynamic environments, the latter on offering high-bandwidth and low-latency access to cellular-equipped mobile nodes. The recent advancements and penetration of software-defined networking (SDN) techniques have stimulated the adoption of SDN-based flexible monitoring and control also for the MANET and FiWi domains. In this perspective, the paper originally proposes a model and an architecture that loosely federate MANET and FiWi domains based on the interaction of MANET and FiWi controllers: the primary idea is that our MANET and FiWi federated controllers can seldom exchange monitoring data and control hints the one with the other, thus mutually enhancing their capability of packet management over hybrid FiWi-MANET networks. Our model is applied to several relevant use cases to practically point out the benefits of the proposal in terms of both load balancing and fairness improvements.

“…An intent is an abstraction used by the applications to specify their high-level desires in form of policies. The ONOS network controller [3], used in our prototype implementation, is the first open-source controller that provide such feature to its applications. The intent is then split by the core into device-specific flow rule requests dispatched to the proper software drivers of the underlying devices.…”

This paper describes a framework application for the control plane of a network infrastructure; the objective is to feature end-user applications with the capability of requesting at any time a customised end-to-end Quality-of-Service profile in the context of dynamic Service-Level-Agreements. Our solution targets current and future real-time applications that require tight QoS parameters, such as a guaranteed end-to-end delay bound. These applications include, but are not limited to, health-care, mobility, education, manufacturing, smart grids, gaming and much more. We discuss the issues related to the previous Integrated Service and the reason why the RSVP protocol for guaranteed QoS did not take off. Then we present a new signaling and resource reservation framework based on the cutting-edge network controller ONOS. Moreover, the presented system foresees the need of considering the edges of the network, where terminal applications are connected to, to be piloted by distinct logically centralised controllers. We discuss a possible inter-domain communication mechanism to achieve the end-to-end QoS guarantee.Copyright c 201x Institute of Advanced Engineering and Science.All rights reserved.Corresponding Author: Name: Francesco Lucrezia Affiliation: Polytechnic of Turin, Italy Address.

Digital contents are consumed by smart phones and sophisticated terminal stations that continuously evolve together with the applications they host. Interestingly enough, the evolution of the OverThe-Top (OTT) services is mainly happening without the aid of network service providers, within the best-effort data traffic channel in the access networks. Recently, a new plethora of applications requiring a RTT delay of around 1ms have been grouped under the hat of tactile-internet applications: a tactile sensor reads information and a connected system reacts with actuators seen by a human within 1 ms [1]. Although we are still far from achieving end-to-end RTT of around 1ms with wireless communications, ISPs need to be ready to re-architect their software control-plane in order to fully exploit the enormous potentials offered by their infrastructures. The goal of this paper is to present the design and a prototype implementation of a control-plane network application for provisioning dynamic end-to-end QoS profiles to end-user applications. The current adoption of distributed control algorithms forces the use of the same signaling protocol (e.g. RSVP, BGP-LS) in all the data-path nodes, not taking into account the resistances inevitably present between device vendors and between administrative domains. For this reason the Service-Level-Agreements (SLAs) between a service provider and its customers or between providers are still mainly static. Moreover, the experience has shown that the scal...
