The deployment of modular virtual network functions (VNFs) in software defined infrastructures (SDI) enables cloud and network providers to deploy integrated network services across different resource domains. It leads to a large interleaving between network configuration through software defined network controllers and VNF deployment within this network. Most of the configuration management tools...
This demo showcases some of the capabilities foreseen for the security infrastructure designed by the H2020 SHIELD project. SHIELD exploits NFV for adaptive monitoring of an IT infrastructure and for feeding the data to an analytics engine to detect attacks in real time. An intelligent reaction system is then activated to reconfigure the SDN/NFV infrastructure so that the attacks are thwarted. The...
Cloud Data Center (DC) service orchestration and resource management are important applications of the Software Defined Networking (SDN) paradigm. In this paper, we introduce a novel dynamic allocation strategy for Virtual Machine (VM) allocation called Enhanced multi-objective Worst Fit (E-WF). E-WF combines the multi-objective Best Fit and Worst Fit allocation strategies, and it exploits the history...
Recent proposals enhances Wireless Sensor Networks (WSNs) with Software Defined Networking (SDN) practices, introducing new innovative network control strategies and protocols based on a central control logic, i.e., enabling WSNs as crucial facilities for the Internet of Things (IoT). In this direction, we demonstrate CORAL-SDN, an SDN solution for WSNs which: (i) uses intelligent centralized control...
Software Defined Networking (SDN) presents a unique opportunity to manage and orchestrate cloud networks. The educational institutions, like many other industries face a lot of security threats. We have established an SDN enabled Demilitarized Zone (DMZ) — Science DMZ to serve as testbed for securing ASU Internet2 environment. Science DMZ allows researchers to conduct in-depth analysis of security...
Residential networks are home to increasingly diverse devices, including embedded devices that are part of the Internet of Things phenomenon, leading to new management and security challenges. However, current residential solutions that rely on customer premises equipment (CPE), which often remains deployed in homes for years without updates or maintenance, are not evolving to keep up with these emerging...
Flexibility and extendibility of Software Defined Networks allows development of diverse network management and flow monitoring techniques. Yet, there are inherent tradeoffs between the quality of flow monitoring and the required network resources. In particular, collecting flow statistics, at the level of specific source-destination addresses (and, moreover, specific protocols and ports), requires...
Network Function Virtualization (NFV) shed new light for the design, deployment, and management of cloud networks. Many network functions such as firewalls, load balancers, and intrusion detection systems can be virtualized by servers. However, network operators often have to sacrifice programmability to achieve high throughput, especially at networks' edge where complex network functions are required...
Traditional network infrastructure is facing significant challenges to support the growing bandwidth, coverage, and latency requirements of users, and to support new 4G and 5G use-cases. As a solution, telecom operators are looking to implement Network Function Virtualization (NFV) in future networks. The placement of Virtual Network Functions (VNFs) plays a critical role in reducing latency to serve...
This demo presents an end-to-end hierarchical control of a multi-domain multi-technology integrated fronthaul and backhaul network where a parent controller coordinates the operation of a wireless and optical child controllers managing real wireless and optical data plane resources. The services offered by this hierarchical control infrastructure are accessed through the offered REST-based northbound...
Due to the abstraction of physical resources and heavy use of virtualization in the context of Service Function Chaining (SFC), verification of the processing and that forwarding of traffic is handled correctly is very challenging. Such verification requires explicit support from the physical cloud infrastructure and — more important — relies on correct configuration and operation of the Cloud Management...
In this paper, we propose two simple and practically feasible countermeasures to address the Route Spoofing and Resource Exhaustion attacks in Software Defined Networking (SDN) scenarios. For Route Spoofing attack, we introduce a new technique called “selective blocking” which blocks an adversary node to use a genuine user's active routes, and for Resource Exhaustion attack, we propose a “periodic...
The Ethernet VPN (EVPN) technology has emerged as a key solution for the interconnection of geo-distributed Data Centers (DCs) over provider-managed MPLS networks. Such interconnections need to satisfy service-level agreements, which can be achieved by enforcing Traffic Engineering (TE) policies. However, deploying an effective TE policy is challenging and complex. This stems from the fact that network...
