With the growing demand for openness, scalability, and granularity, mobile network function
virtualization (NFV) has emerged as a key enabler for the most of mobile network operators …

The exponential growth of mobile applications and services during the last years has
challenged the existing network infrastructures. Consequently, the arrival of multiple …

Virtual network embedding arranges virtual network services onto substrate network
components. The performance of embedding algorithms determines the effectiveness and …

The introduction of the Internet of Things (IoT) and massive machine-type communications
has implied an increase in network size and complexity. In particular, there is already a huge …

Network slicing allows mobile operators to offer, via proper abstractions, mobile
infrastructure (radio, networking, computing) to vertical sectors traditionally alien to the telco …

5G-and-beyond networks are designed to fulfill the communication and computation
requirements of various industries, which requires not only transporting the data, but also …

With the increasing trend in softwarization and virtualization of network functions and
systems, NFV management and orchestration (MANO) solutions are being developed to …

Abstract Network Function Virtualization (NFV) is an approach to virtualizing network
services that traditionally run on proprietary hardware, such as firewalls, routers, and load …

The last decade has witnessed important development of network softwarization that has
revolutionized the practice of networks. Virtualized networks bring novel and specific …

Networks can now process data as well as transporting it; it follows that they can support
multiple services, each requiring different key performance indicators (KPIs). Because of the …
