“…8c shows the β (2) estimates obtained based on Eq. (14). Although the input and estimated values follow the same trend, a relatively higher variance (and hence, errors) are observed inβ (2) stemming from the fact that the starting point was the busy times (i.e., Eq.…”

“…Other ways for reducing the virtualization overhead regard the handling of network I/O. A number of works in the scientific literature (e.g., [14]- [16], among others) consider technologies like Single Root I/O Virtualization (SR-IOV) and Intel's Data Plane Development Kit (DPDK), which bypass the OS network stack. However, this entails building a specialized network stack on applications that require one, and the device cannot be shared with other applications [13].…”

Network Functions Virtualization (NFV) has recently gained much popularity in the research scene for the flexibility and programmability that it will bring with the software implementation of network functions on commercial offthe-shelf (COTS) hardware. To substantiate its roll out, a number of issues (e.g., COTS' inherent performance and energy efficiency, virtualization overhead, etc.) must be addressed, in a scalable and sustainable manner. Numerous works in the scientific literature manifest the strong correlation of network key performance indicators (KPIs) with the burstiness of the traffic. This paper proposes a novel model-based analytics approach for profiling virtualized network function (VNF) workloads, towards real-time estimation of network KPIs (specifically, power and latency), based on an M X /G/1/SET queueing model that captures both the workload burstiness and system setup times (caused by interrupt coalescing and power management actions). Experimental results show good estimation accuracies for both VNF workload profiling and network KPI estimation, with respect to the input traffic and actual measurements, respectively. This demonstrates that the proposed approach can be a powerful tool for scalable and sustainable network/service management and orchestration.

<span>Multiprotocol Label Switching (MPLS) is a promising packet switching technology in the field of communication network, allowing router to forward the packets based on labels. However, off-the-shelves routers are made to be non-configurable, making it less suitable for academic research purposes. The aim of this paper is to explore the possibility of developing a configurable MPLS router by reviewing embedded system-based router, software-based router and commercial MPLS router itself. The architecture of the routers will be described in detail and their performances will be compared. From the analysis, we found that the development of reconfigurable MPLS router testbed is achievable by using embedded system-based hardware due to its freedom of reconfigurability.</span>

“…Also, it is important to keep in mind that providing and maintaining a highly dependable configuration will be the responsibility of the network operator, which in a transition phase may constitute a challenge with respect to the available competence. • The need to meet the performance requirements in the data plane has pushed the introduction of acceleration modules, such as DPDK, which provide more autonomy in the user space and reduce the load of the kernel space [13], [14]. At the same time, these improvements introduced new dependability dimensions that need to be considered.…”

The introduction of Network Function Virtualisation (NFV) represents a significant change in networking technology, which may create new opportunities in terms of cost efficiency, operations, and service provisioning. Although not explicitly stated as an objective, the dependability of the services provided using this technology should be at least as good as conventional solutions. Logical centralisation, off-the-shelf computing platforms, and increased system complexity represent new dependability challenges relative to the state of the art. The core function of the network, with respect to failure and service management, is orchestration. The failure and misoperation of the NFV Orchestrator (NFVO) will have huge network-wide consequences. At the same time, NFVO is vulnerable to overload and design faults.Thus, the objective of this paper is to give a tutorial on the dependability challenges of the NFVO, and to give insight into the required future research. This paper provides necessary background information, reviews the available literature, outlines the proposed solutions, and identifies some design and research problems that must be addressed.
