“…This is mostly related to the advances in SDN technology and the need for timely network monitoring and configuration. A number of studies on INT realization for different host environments and networks have been performed [18]- [21]. A number of demos have been shown too, illustrating how INT can be used to diagnose network problems as well as to improve network performance [22], [23].…”

Most industrial applications demand determinism in terms of latency, reliability, and throughput. This goes hand in hand with the increased complexity of real-time network programability possibilities. To ensure network performance low-overhead, high-granularity, and timely network verification techniques need to be deployed. The first cornerstone of network verification ability is to enable end-to-end network monitoring, including end devices too. To achieve this, this article shows a novel and low overhead in-band network telemetry and monitoring technique for wireless networks focusing on IEEE 802.11 networks. A design of in-band network telemetry enabled node architecture is proposed and its proof of concept implementation is realized. The PoC realization is used to monitor a real-life SDN-based wireless network, enabling onthe-fly (re)configuration capabilities based on monitoring data. In addition, the proposed monitoring technique is validated in terms of monitoring accuracy, monitoring overhead, and network (re)configuration accuracy. It is shown that the proposed inband monitoring technique has 6 times lower overhead than other active monitoring techniques on a single-hop link. Besides this, it is demonstrated that (re)configuration decisions taken based on monitored data fulfill targeted application requirements, validating the suitability of the proposed monitoring technique.

“…The term "in-band" refers to the fact that telemetry data is carried within data packets rather than being sent within specifically dedicated packets. Therefore, it does not need for artificial probing packets or dedicated middle-boxes, and the network state is obtained at the exact point in time the real user traffic passes through [12]. Also, the insertion of inband information does not change the forwarding behavior of the packet.…”

“…Although INT is not yet a widely used industry standard, it has already been applied to a number of non-constrained networking platforms; e.g. SDN, Cloud [12], [27], [28]. However, INT operations, data models, header formats, encoding and data types defined by P4 (as defined in [29]) were not designed by considering the limitations and characteristics of the wireless and/or constrained networks and the needs of Industrial WSNs and 6TiSCH Networks.…”

“…In this regard, the key research problem of this work is the design of more intelligent and efficient monitoring solutions and flexible management architectures for wireless industrial networking technologies, more specifically the 6TiSCH Network stack [4]. For this purpose, the recently proposed concept of In-Band Network Telemetry (INT), by the P4 Language Consortium [11], is adopted, which allows the collection and reporting of network state without any need for artificial probing packets and at the exact moment when real user traffic traverses them [12]. Since the state-of-the-art INT techniques are only being explored for wired networks [11], these mechanisms need to be redesigned in order to meet the aforementioned key requirements.…”

With the emergence of the Internet of Things (IoT) and Industry 4.0 concepts, industrial applications are going through a tremendous change that is imposing increasingly diverse and demanding network dynamics and requirements with a wider and more fine-grained scale. Therefore, there is a growing need for more flexible and reconfigurable industrial networking solutions complemented with powerful monitoring and management functionalities. In this sense, this paper presents a novel efficient network monitoring and telemetry solution for Industrial Wireless Sensor Networks mainly focusing on the 6TiSCH Network stack, a complete protocol stack for ultrareliable ultra-low-power wireless mesh networks. The proposed monitoring solution creates a flexible and powerful in-band network telemetry design with minimized resource consumption and communication overhead while supporting a wide range of monitoring operations and strategies for dealing with various network scenarios and use cases. Besides, the technical capabilities and characteristics of the proposed solution are evaluated via a real-life implementation, practical and theoretical analysis. These experiments demonstrate that in-band telemetry can provide ultra-efficient network monitoring operations without any effect on the network behavior and performance, validating its suitability for Industrial Wireless Sensor Networks.

“…Permite-se, por meio da programação de dispositivos de encaminhamento, a inclusão de informações de monitoramento (por exemplo, tamanho da fila de um dispositivo, tempo de processamento de um pacote) nos próprios pacotes dos tráfegos de rede ativos. Essas informações fornecem maior cobertura sobre o estado da rede, auxiliando no gerenciamento da infraestrutura de rede e suas aplicações [Tammana et al 2018, Jianzhe Liang 2018, [Gulenko et al 2018].…”

A telemetria in-band surgiu recentemente como uma alternativa ao monitoramento tradicional e permite encapsular informações de monitoramento com uma granularidade mais fina a partir do plano de dados permitindo aumentar o nível de visibilidade fornecido ao operador. Nesse sentido, pouco ainda foi feito para orquestrar a coleta de dados relacionados a telemetria in-band. Neste artigo, propõe-se duas heurísticas online para coletar informações de telemetria baseadas nas estratégias round-robin e least recently collected. Resultados mostram que as heurísticas projetadas conseguem coletar os dados de telemetria com 30% a mais de frequência e com maior uniformidade ao longo do tempo que as abordagens existentes.
