Projeto e desenvolvimento de um processador NSH para serviços encadeados de rede

Abstract

One of the major difficulties of the telecommunications industry is the dependence of physical resources for the execution of its services. Network Function Virtualization (NFV) has come up to solve this problem. The idea of NFV is to decouple physical network equipment from the functions they perform. With the advent of NFV, network service instances run on multiple clouds for performance and load balancing purposes. In this context, Service Function Chaining (SFC) is defined, which is a mechanism that allows multiple network functions to be interconnected to form a service, allowing operators to benefit from the infrastructure defined by virtualized software. To meet the needs of the SFC, the Network Service Header (NSH) emerge, a data-plane protocol that acts as an encapsulation for SFCs. Thus, this work aims at the development of an NSH Processor for Service Function Chaining. For this, a survey was made of the necessary requirements for the implantation followed by the choice of tools that met these requirements effectively. Finally, since there are no available implementations of NSH Processors up to the time of this work, the developed processor was evaluated and judged qualitatively.
