The integration of Time-Sensitive Networks (TSN) with 5G cellular networks requires a defined architecture for network configuration and management. Although 3GPP specifications provide necessary means for the TSN-5G integration, the operation of such converged TSN-5G network remains an open challenge for the research community. To address this cha...

Novel industrial applications are leading to important changes in industrial systems. One of the most important changes is the need for systems that are capable to adapt to changes in the environment or the system itself. Because of their nature many of these applications are distributed, and their network infrastructure is key to guarantee the cor...

The Time-Sensitive Networking (TSN) Task Group has standardised different mechanisms to provide Ethernet with hard real-time guarantees and reliability in layer 2 of the network architecture. Specifically, TSN proposes using space redundancy to increase the reliability of Ethernet networks, but using space redundancy to tolerate temporary faults is...

In recent years the Time-Sensitive Networking (TSN) Task Group (TG) has been working on proposing a series of standards to provide Ethernet with hard real-time guarantees, online management of the traffic and fault tolerance mechanisms. In this way the TG expects to create the network technology of future novel applications with real-time and relia...

The IEEE Audio Video Bridging (AVB) Task Group (TG) was created to provide Ethernet with soft real-time guarantees. Later on, the TG was renamed to Time-Sensitive Networking (TSN) and its scope broadened to support hard real-time and critical applications. The Stream Reservation Protocol (SRP) is a key work of the TGs as it allows reserving resourc...

Industry 4.0 and Autonomous Driving are emerging resource-intensive distributed application domains that deal with open and evolving environments. These systems are subject to stringent resource, timing, and other non-functional constraints, as well as frequent reconfiguration. Thus, real-time behavior must not preclude operational flexibility. Thi...

In the above article [1] , the last funding acknowledgment “[…] and in part by the Research Centre Instituto de Telecomunicações under Grant UID/EEA/50008/2013.” is incorrect and outdated. The correct acknowledgment is “[…] and in part by FCT/MCTES through national funds and when applicable co-funded EU funds under the project UIDB/50008/ 2020-UI...

Many industrial systems have specific requirements derived from the applications they execute. Specifically, the interaction of a distributed embedded control system (DECS) with the real-world imposes strict real-time (RT) and reliability requirements. For a system to be RT, it has to produce a proper result in a bounded time. On top of that, for a...

Time-Sensitive Networking (TSN) is a set of technical standards that is being developed to provide Ethernet with hard real-time, reliability and flexibility services. In the last years, there has been a growing interest in increasing the connectivity of all kind of devices. This trend has reached industrial environments, where the demanding timing...

Comparación de los mecanismos de Control de Admisión de los protocolos Flexible Time-Triggered y Audio Video Bridging; desde el punto de vista de las vulnerabilidades presentes en la arquitectura y en el diseño del mecanismo; la flexibilidad que ofrece a la red en cuanto a la conexión y desconexión de usuarios y a la gestión de la calidad de servic...

There is a growing interest in developing embedded systems capable of being deployed in dynamic environments that may change in unpredictable manners. When such systems are Distributed Embedded Systems (DESs) they must exhibit flexibility at all levels of their architecture, including the network. On the other hand, there is a clear trend in indust...

Distributed embedded systems typically have real-time and dependability requirements. Moreover, they must also be flexible to changing conditions when they are deployed in dynamic environments. The FT4FTT project aims at providing a switched Ethernet architecture that can support distributed control applications that are predictable, highly-reliabl...

The communication subsystem of distributed embedded systems (DES) that must operate continuously and satisfy unpredictable requirement changes must be reliable and flexible. Recently the Flexible Time-Triggered Replicated Star for Ethernet (FTTRS) has been proposed as a communication subsystem that satisfies these two attributes. It is based on the...
