Optimizing Network Performance and Reliability with an Integrated SD-WAN and Satellite 6G Architecture
No full textAbstract—Integrating Software-Defined Wide Area Networking (SD-WAN) and Satellite 6G can provide a new architecture
offering improved performance and reliability for various applications. SD-WAN provides a flexible and efficient system to
manage network traffic across multiple locations. At the same
time, Satellite 6G aims to offer an intelligent network with
high-speed connectivity, global coverage, and ultra-reliability. By
integrating these two technologies, we propose an innovative
architecture that can support applications in remote areas or
high-latency environments. Furthermore, the proposed architecture can be optimized to meet the specific requirements of
different applications, enabling new use cases such as remote
medicine, precision agriculture, and autonomous vehicles. Our
work contributes to the emerging Satellite 6G and SD-WAN
integration field and provides a basis for further research.

A reparameterization and monitoring platform for energy efficient GPS trackers in behavioural analysis of wildlife
No full textIn this paper, we present the architecture of a platform designed to monitor wildlife behaviour. The idea starts from the need to monitor the behavioural habits of wildlife throughout the year, in large observation areas, and with regular monitoring phases (i.e., at specific day and night times and for a certain number of months), together with the possibility of modifying the time when a device sends the localization data through a remote adaptive reparameterization process. To have a cost-effective solution in the wide areas to be covered, the platform implementation aims to monitor wildlife in an adaptive way, in relation to the seasonality and anomalous animal behaviours, obtaining reliability and energy efficiency. The platform is composed of GPS tracker devices that send localization data to a Field Programmable Gate Array (FPGA) board that collects the data and uses them for making decisions about the reparameterization of the devices. Next, the data are forwarded to a Cloud application used for the monitoring and where specific algorithms identifies the optimal strategy for remote reparameterization of the devices in case of any anomalies in the behavioural wildlife. To achieve flexibility and scalability of the architecture, modern virtualization technologies have been proposed for the development of the monitoring application using a time series database running on a Cloud platform
Performance Analysis of the Control and Forwarding Plane in MPLS router
No full textMultiprotocol Label Switching (MPLS) was originally designed to provide higher packet forwarding rates in network equipment. Nevertheless, it was soon realized that it could also provide other advanced features, such as Traffic Engineering and Virtual Private Networks capabilities. The key feature of MPLS is a strict separation between control and forwarding operations, which reflects on the software and hardware architecture of the routers. The paper presents the results of an experimental study aimed at evaluating the performance of a Label Switching Router (LSR). In particular, the behaviour of the LSR control and forwarding planes has been analyzed in different working conditions as it concerns both the processing and computational effort due to the control plane and the data traffic to be forwarded

Design and development of MPLS-based recovery strategies in NS2
No full textIn a multi-service IP network, it is a key challenge to provide QoS to end-user applications while effectively using network resources. Traffic Engineering support in MPLS networks allows operators to carry traffic with strict QoS requirements by means of advanced network capabilities, such as resource reservation, fault-tolerance and optimization of transmission resources. To deliver a reliable service, MPLS exploits a set of procedures that protect the traffic flows carried on different paths. Therefore, Label Switching Routers have to support mechanisms for fault detection, notification and recovery, whereas MPLS has to enable the configuration of different recovery techniques. In this paper, we present the design and the development of some software modules for the simulation of different MPLS-based recovery strategies in the discrete event simulator NS2. Moreover, the paper discusses some simulation results that show a performance comparison between path protection and path restoration strategies in a simulation scenario matching the Géant networ
