Latency Measurement as a Virtualized Network Function using Metherxis

Abstract

Network latency is critical to the success of many highspeed, low-latency applications. RFC 2544 discusses and defines a set of tests that can be used to describe the performance characteristics of a network device. However, most of the available measurement tools cannot perform all the tests as described in this standard. As a novel approach, this paper proposes Metherxis, a system that can be implemented on general purpose hardware and enables Virtualized Network Functions (VNFs) to measure network device latency with micro-second grade accuracy. Results show that Metherxis achieves highly accurate latency measurements when compared to OFLOPS, a well known measurement tool.

“…To measure network with micro-second grade accuracy, we used a tool named Metherxis [15]. A workload is configured to send a traffic at rate of 100Mbps during 30 seconds from host 1 to host 16 for 30 rounds.…”

“…O uso de microsserviços baseados em containers para implementação de ferramentas de medição e monitoramento tem se mostrado uma tendência na literatura, especialmente me função da possibilidade de transformação destas ferramentas em Funções Virtuais de Monitoramento de Redes (VNMFs, ou Virtual Network Monitoring Functions) [7]. O Metherxiś e uma VNMF para medição de latência de dispositivos de rede, com precisão de microssegundos, implementada com a tecnologia de microsserviços usando Linux Containers como infraestrutura de desenvolvimento.…”
