Program slicing is a technique for identifying a subprogram from an original program. The subprogram, called a slice, is an executable program which maintains the eeect of the original upon a chosen set of variables at some point within the Control Flow Graph (CFG) of the original. The variable set, CFG node pair is called the slicing criterion. Slices nd applications in debugging, testing, par...

Communication systems are used not only by voice or file exchange applications, but also other types of applications due to the coexistence multiple and different verticals. Each vertical has its own requirements in terms key performance indicators (KPIs) for their applications. Mapping verticals KPIs into network quality service (QoS) parameters enforcing it at level is a complex procedure. Ne...

5G mobile networks are envisioned to substantiate new vertical services with diverse performance requirements. Slicing in the radio access network (RAN) promises an efficient solution for these diversified needs of networks, which foresees separation base station functionality between central unit (CU) and distributed remote heads. In this article, we formulate a mixed integer programming (MIP)...

Developing specialized cloud-based and open-source testbeds is a practical approach to investigate network slicing functionalities in the fifth-generation (5G) mobile networks. This paper provides comprehensive review of most existing cost-efficient small-scale that partially or fully deploy slicing. First, we present relevant software packages for three main functional blocks ETSI NFV MANO fra...
