Abstract Quick handling of link failures remains a challenging issue in current communication networks, although it is crucial to many routing algorithms. Link are the leading cause packet losses and delays, therefore, failure recovery tied stringent requirements for certain services, such as sub-50 millisecond completion time carrier-grade which sometimes difficult achieve traditional schemes. For this reason, fast strategies key pillars modern networks. In paper, we demonstrate benefits...
The Platform-as-a-Service (PaaS) model, allows service providers to build and deploy their services following streamlined work-flows. However, platforms deployed through the PaaS model can be very diverse in terms of technologies involved subsystems (e.g. infrastructure, orchestration). Thus, means for deploying managing a significantly vary depending on platform. To address this issue, paper proposes policy-based framework designed Next Generation (NGPaaS). This define platform-wide...
Software-Defined Networking (SDN) has introduced ways to detect and manage potential vulnerabilities in Internet-of-Things (IoT) networks. On the IoT Edge, when Edge servers may be vulnerable attacks like Distributed Denial of Service (DDoS), fast feature extraction attack detection are vital for timely mitigation. The capabilities SDN networks, however, limited by latency imposed collection from control plane. In this paper, we present a DDoS method deploying programmable switches on Edge....
Global System for Mobile communication - Railway (GSM-R) is widely used operational communications between train and signaler.

While not difficult learn, Graph-to-P4 offers possibility first draw graphs, generate starter and finally let programmers develop specific data plane behavior (actions, tables, etc.). We have experienced smooth...
When Software-Defined Networks (SDN) gained popularity, different control plane applications could run together to manage vendor-agnostic OpenFlow data planes. With the adoption of P4, developers realized that P4 logic developed for one particular model and target not be modularly shared, preventing fast adoption. As a result, pipeline's specific functionality can exported incorporated into another pipeline without necessary manual adaptations. we present early work P4click, Next-Generation...

Distributed real-time systems often rely on time-triggered communication and task execution to guarantee end-to-end latency time-predictable computation. Such require a reliable synchronized network time be shared among end-systems. The IEEE 1588 Precision Time Protocol (PTP) enables such clock synchronization throughout an Ethernet-based network. While security was not addressed in previous versions of the standard, its most recent iteration (IEEE 1588-2019), several mechanisms...
In the last years, Software-Defined Networking (SDN) has provided a new approach to network programmability, first regarding control plane and later data plane.
