NFV-TE: Automatic System to Generate Virtualized Network Functions for Traffic Engineering
Abstract
This work presents NFV-TE, a traffic engineering framework based on
NFV technology (Network Function Virtualization). The NFV paradigm brings
flexibility to networks by allowing the implementation of core functions on a
software plane. After the network operator enters a set of characteristics of the
desired traffic engineering mechanism, NFV-TE validates and consolidates the
data on a JSON configuration file, from which the corresponding virtual network
function is generated. NFV-TE is an extensible solution, designed to allow the
addition of arbitrary functions, which can be easily instantiated and configured.
This paper describes the various policers and shapers that are already present
in NFV-TE, describing their execution in different scenarios and under different
network traffic profiles.
