The increasing need for high-precision monitoring and network-wide observability has spurred significant interest in In-Band Network Telemetry (INT), which empowers the collection of monitoring data directly from the dataplane, thus, alleviating the various shortcomings of passive monitoring…

IoT-enabled applications benefit from various forms of digital twinning, such as the so-called Virtual Objects (VOs). A crucial requirement in the communication among IoT devices and their associated VOs is low latency. In this respect, we showcase a software platform for Time-Sensitive Networking…

Over the last years, we have seen the emergence of (hyper-)distributed applications, which tend to be provisioned over resources that span IoT devices, IoT gateways, and compute nodes from edge computing infrastructures. The deployment and orchestration of such services benefits from types of IoT…

5G and cloud computing are set out to address various business needs, often related to the deployment of IoT-enabled applications across the compute continuum. However, the provision of such hyper-distributed applications is far from trivial, due to various interoperability and convergence aspects…

Network Function Virtualization (NFV) opens us great opportunities for network processing with higher resource efficiency and flexibility. In this respect, there is an increasing need for intelligent orchestration mechanisms, such that NFV can exploit its potential and live up to its promise.…

Network Function Virtualization (NFV) has paved the way for the migration of Virtual Network Functions (VNFs) into multi-tenant datacenters, lowering the barrier for the introduction of new processing functionality into the network. Recent trends for resource orchestration across the entire compute…

In-band network telemetry (INT), empowered by programmable dataplanes such as P4, comprises a viable approach to network monitoring and telemetry analysis. However, P4-INT as well as other existing frameworks for INT yield a substantial transmission overhead, which grows linearly with the number of…

Time-Sensitive Networking (TSN) aspires to provide a solid underpinning for meeting latency guarantees across traffic classes with diverse requirements. Despite the emergence of various specifications from the TSN family of standards, there is a shortage of prototype implementations with support…
