Abstract-The fifth generation (5G) wireless networks are expected to offer high capacity and accommodate numerous overthe-top (OTT) applications, relying on users' Internet connectivity, thus involving different stakeholders, i.e., network service providers (NSPs) and OTT service providers (OSPs). For the efficient management of OTT application flows, the implementation of service functions and their interconnection in service chains, namely the network service chaining (NSC), should consider the OSPs' performance goals and user management strategies. However, in current wireless network deployments, the NSPs have full control of NSC. Considering that user satisfaction from the offered services is common interest for both types of stakeholders, the OSPs need to participate in NSC and apply QoS and user prioritization policies to NSC resource management, which involves users connected in different network points, in a distributed manner. In this article, we describe 5G network management architectures and propose virtualization components that enable OSP-oriented NSC. We also outline the arising issues for OSPs in NSC and we introduce a distributed prioritization NSC management scheme for OTT application flows, based on matching theory. The evaluation results indicate the performance gains in OSPs' service levels that stem from the proposed scheme, demonstrating the benefits of introducing prioritization in NSC deployment.

Abstract-Proliferation of the number of smart devices and user applications has generated a tremendous volume of data traffic from/to a cellular network. With a traditional cellular network, a user may experience many drawbacks such as low throughput, large latencies and network outages due to overload of data traffic. The software defined networking (SDN) and network function virtualization (NFV) rise as a promising solution to overcome such issues of traditional network architecture. In this paper, we introduce a new network architecture for LTE and WiFi slicing networks taking into account the advantage of SDN and NFV concepts. We propose an IP-Flow management controller in a slicing network to offload and balance the data traffic flow. By utilizing the P-GW and Wireless Access Gateway, we can handle the IP-Flow between LTE and WiFi networks. The P-GW works as an IP-Flow anchor to maintain the flow seamlessly during the offloading and balancing IP-Flow. Within WiFi networks, we leverage the Light Virtual Access Point (LVAP) approach to abstract the WiFi protocol stack for a programming capability of centralized control of WiFi network through the WiFi controller. By creating a client virtual port and assigning a specific Service Set Identifier (SSID), we give a capability to slice an operator's network to control over his clients within a WiFi coverage area network.

“…C-RAN implementation is often associated to other complementary architectures, such as, e.g., NFV and SDN (see e.g. [55], [43], [56]). The C-RAN provides benefits to operators and end-customers by enabling improved interference control, and thereby improved throughput, and by providing higher elasticity and scalability thanks to centralisation of BBUs.…”

Abstract-Due to the increasing dependence on network services of our society, research has recently been concentrating on enhancing traditional protection strategies to withstand largescale failures, as in case of disaster events. The recently-formed EU-funded RECODIS project aims at coordinating and fostering research collaboration in Europe on disaster resiliency in communication networks. In particular, the Working Group (WG) 2 of the RECODIS project focuses on developing new networkresiliency strategies to survive weather-based disruptions. As a first step, WG2 members have conducted a comprehensive literature survey on existing studies on this topic. This paper classifies and summarizes the most relevant studies collected by WG2 members in this first phase of the project. While the majority of studies regarding weather-based disruptions deals with wireless network (as wireless channel is directly affected by weather conditions), in this survey we cover also disasterresiliency approaches designed for wired network if they leverage network reconfiguration based on disaster "alerts", considering that many weather-based disruptions grant an "alert" thanks to weather forecast.
