Abstract In this paper we describe P4-SFC to support service function chaining (SFC) based on a single P4-capable switch and off-the-shelf components. It utilizes MPLS-based segment routing for traffic forwarding in the network and SR-IOV for efficient packet handling on hosts. We describe the P4-SFC architecture and demonstrate its feasibility by a prototype using the Tofino Edgecore Wedge 100BF-32X as P4 switch. Performance test show that L2 throughput for VNFs on a host is significantly larger when connected via SR-IOV with the host’s network interface card instead of over a software switch.

The designs of highly scalable intelligent sensory application—Ethernet-based communication architectures—are moving toward the integration of a fault recovery and fault-detection algorithm on the automotive industry. In particular, each port on the same network interface card design is required to provide highly scalable and low-latency communication. In this article, we present a study of intelligent sensory application for the Ethernet-based communication architecture and performance of multi-port configuration which is mainly used in safety-enhanced application such as automotive, military, finance, and aerospace, in other words, safety-critical applications. Our contributions and observations on the highly scalable intelligent behavior: (1) proposed network interface card board design scheme and architecture with multi-port configuration are a stable network configuration; (2) timing matrix is defined for fault detection and recovery time; (3) experimental and related verification methods by cyclic redundancy check between client–server and testing platform provide comparable results to each port configurations; and (4) application program interface–level algorithm is defined to make network interface card ready for fault detection.

Há diferentes dispositivos para facilitar o acesso ao computador, porém, poucos estudos para verificar a eficácia dos mesmos. O objetivo deste estudo foi comparar o desempenho de jovens ao utilizarem dispositivos de acesso ao computador. Participaram do estudo cinquenta jovens saudáveis com idades entre 15 e 25 anos. Para a coleta de dados foi utilizado computador com tela sensível ao toque, mouse e o Camera Mouse. Foram utilizados três softwares para avaliar tempo de reação e acurácia dos participantes: Discrete Aiming Task, Tracking Task e Single Switch Performance Test. Para conhecer o grau de satisfação de uso dos dispositivos, foi utilizado o Quebec User Evaluation of Satisfaction with Assistive Technology. O resultados demonstraram que nas atividades de precisão e tempo de reação, o mouse e a toque na tela foram os dispositivos que geraram os melhores desempenhos. Conclui-se que, o Camera Mouse foi o dispositivo que gerou os piores desempenhos.
