Mitigating Satellite Link Variability in SD-WAN using Constellation-Aware Edge Routing
No full textLow Earth Orbit (LEO) satellite constellations are rapidly expanding global Internet access, offering increasingly cost-effective connectivity. Compared to geostationary systems, LEO networks provide the potential for significantly higher bandwidth and lower latency, making them technologically attractive. This performance potential, combined with ubiquitous coverage extending to remote and underserved areas, positions LEO as a compelling underlay technology for Software-Defined Wide Area Networks (SD-WAN), promising enhanced enterprise connectivity. However, recent network measurements have highlighted a critical challenge: LEO's highly dynamic topology induces significant latency variability and packet reordering, straining traditional reactive SD-WAN path selection mechanisms and impacting applications with strict performance requirements. To unlock LEO's full potential for SD-WAN, we propose a novel Constellation-Aware architecture. Our approach embeds a lightweight predictive satellite simulator within the edge Customer Premises Equipment (CPE). By leveraging ephemeris data to anticipate path changes and predict delay variations, the system enables proactive routing insights, allowing traffic steering before significant degradation occurs. This edge-centric design mitigates LEO link variability, enhancing SD-WAN reliability over satellite without requiring satellite network modifications
Software Defined Wide Area Networking (SD-WAN)
No full textA reliable Wide Area Network (WAN) has become a necessity for businesses
to transmit critical data across multiple branches and to increase their revenues. Many
solutions and dierent network structures have been proposed over years such as leased
lines, Frame Relay or Multi-Protocol Label Switching Virtual Private Networks (MPLS
VPN). Each solution is intended to be better than its predecessors in terms of reliabil-
ity and Quality of Service (QoS). Software-Dened Wide Area Networking (SD-WAN)
is an emerging paradigm that introduces the advantages of software dened networking
(SDN) into enterprise networking. SD-WAN can support dierentiated services over pub-
lic WAN by dynamically changing the
ow forwarding rules over an overlay network based
on monitoring data and service requirements. Thanks to these capabilities, it is possible to
overcome high cost of guaranteed QoS services such as MPLS. Most of the SD-WAN so-
lutions commercially available today are based on proprietary controllers and proprietary
Customer Provider Edge (CPE) devises. In this chapter, we present an implementation
of SD-WAN based on open source components such as OpenDaylight SDN controller and
Open Virtual Switch (OvS). This work targets the monitoring features of an SD-WAN
solution and explores active and passive monitoring approaches to understand their ad-
vantages and limitations. Our implementation provides an overlay WAN with controlled
performance in terms of delay and losses over low-cost Internet connectivity
Student Expectations in the New Millennium
No full textHigher education has experienced vast changes as a result of global political and economic developments. Cultural and social changes in the last decade have also added to the continuing evolution of higher education. These changes inevitably lead to changing expectations of students entering higher education. An adequate understanding of student expectations is crucial in ensuring a good fit between higher educational institutions and their students. This study attempts to carry out a baseline descriptive-quantitative research on student expectations in the higher education of Hong Kong. Four scales have been developed to measure students’ attitude toward: 1. job-oriented curriculum design, 2. user-friendly course delivery method, 3. opportunities for lifelong learning, and 4. student consumerism. Students’ priority of what makes a good university, their reasons for going to university, and their self-perception of ability to cope with university life are also explored. The Student Expectations Questionnaire (developed by the author) was used to gather data from 857 first-year undergrads from nine institutions of higher education in Hong Kong. Analyses include, among others, gender, age, major of study as well as institution comparisons
Towards an Intelligent and Satellite-Integrated SD-WAN: A High-Performance and Availability-Aware Approach
No full textSoftware-Defined Wide Area Networks (SD-WANs) provide flexibility and cost-efficiency but still face significant challenges in guaranteeing high availability and consistent performance, particularly when utilizing diverse internet access networks, especially if best-effort like broadband connectivity. Furthermore, reliance on centralized controllers can introduce bottlenecks and single points of failure. This paper outlines a PhD research roadmap aimed at developing a resilient, performant, and extensible SD-WAN framework. The proposed research starts with robust modeling of service-oriented availability considering control plane impacts and quality of service requirements. This will guide us through an availability-aware SD-WAN modular architecture with the function of simplifying the development and test of new features such as: strategies to enhance edge autonomy by reducing real-time controller dependency; integration of predictive awareness tailored to specific internet access networks as LEO satellite based; and experimenting advanced monitoring for intelligent and reactive edge-based traffic engineering. We present the research context, state-of-the-art limitations, core research questions, the methodology combining modeling, simulation, and prototype development, and the expected contributions towards next-generation SD-WAN architectures suitable for research and demanding enterprise applications
Resilience of Delay-sensitive Services with Transport-layer Monitoring in SD-WAN
No full textToday, more and more enterprises are embarking on a digital transformation where most of their applications are hosted in the Cloud. As a result, a reliable Wide Area Network (WAN) has become a primary need to interconnect their distributed branch offices and data centers that accommodate those applications. Software-Defined Wide Area Network (SD-WAN) represents the most promising technology solution for next-generation enterprise networks, being able to increase network agility and reduce costs. In this paper, we present an experimental SD-WAN solution capable of running and optimizing delay-sensitive high-priority services, such as real-time video streaming, while minimizing downtime caused by network failures. This solution comprises a monitoring and a traffic engineering system for SD-WAN. The first consists of a Transport-layer Passive Monitoring (TPM) system based on extended Berkeley Packet Filter (eBPF) technology with the goal of monitoring TCP flows; the second consists of an application, running inside the SD-WAN controller, with the goal of orchestrating the network traffic in consideration of the monitoring measurements by ensuring rapid recovery and resilience in case of unexpected congestion events. We validate our solution over two SD-WAN testbeds: the first is hosted in our laboratory at Politecnico di Milano, while the second is deployed in a municipal network of an Italian city. Results show that our SD-WAN solution can increase the overall service availability while meeting the stringent QoS requirements of delay-sensitive services
