A Highly-Available Multiple Region Multi-access Edge Computing Platform with Traffic Failover

One of the main challenges in the Multi-access Edge Computing (MEC) is steering traffic from clients to the nearest MEC instances. If the nearest MEC fails, a failover mechanism should provide mitigation by steering the traffic to the next nearest MEC. There are two conventional approaches to solve this problem, i.e., GeoDNS and Internet Protocol (IP) anycast. GeoDNS is not failover friendly because of the Domain Name System (DNS) cache lifetime. Moreover, the use of a recursive resolver may inaccurately translate the IP address to its geolocation. Thus, this thesis studies and proposes a highly available MEC platform leveraging IP anycast. We built a proof-of-concept using Kubernetes, MetalLB, and a custom health-checker running on the GNS3 network emulator. We measured latency, failure percentage, and Mean Time To Repair (MTTR) to observe the system's behavior. The performance evaluation of the proposed solution shows an average recovery time better than one second. The number of failed requests and latency overhead grows linearly as the failover time and latency between two MECs increases. This thesis demonstrates the effectiveness of IP anycast for MEC applications to steer the traffic to the nearest MEC instance and to enhance resiliency with minor overhead

Imagining the Internet in Future

In this paper, we imagining the Future Internet (ICN and NDN architecture). We discuss examples of edge computing and IoT. We chose these areas because they are very important topics in today research. We also discuss provider mobility, P2P architectures, sync, and simulation tools. We discuss open questions for research

Resource virtualisation of network routers

There is now considerable interest in applications that transport time-sensitive data across the best-effort Internet. We present a novel network router architecture, which has the potential to improve the Quality of Service guarantees provided to such flows. This router architecture makes use of virtual machine techniques, to assign an individual virtual routelet to each network flow requiring QoS guarantees. We describe a prototype of this virtual routelet architecture, and evaluate its effectiveness. Experimental results of the performance and flow partitioning of this prototype, compared with a standard software router, suggest promise in the virtual routelet architecture

Real Time Control for Intelligent 6G Networks

The benefits of telemetry for optical networking have been shown in the literature, and several telemetry architectures have been defined. In general, telemetry data is collected from observation points in the devices and sent to a central system running besides the Software Defined Networking (SDN) controller. In this project, we try to develop a telemetry architecture that supports intelligent data aggregation and nearby data collection. Several frameworks and technologies have been explored to ensure that they fit well into the architecture's composition. A description of these different technologies is presented in this work, along with a comparison between their main features and downsides. Some intelligent techniques, aka. Algorithms have been stated and tested within architecture, showing their benefits by reducing the amount of data processed. In the design of this architecture, the main issues related to distributed systems have been faced, and some initial solutions have been proposed. In particular, several security solutions have been explored to deal with threats but also with scalability and performance issues, trying to find a balance between performance and security. Finally, two use cases are presented, showing a real implementation of the architecture that has been presented at conferences and validated within the project's development

Ethernet - a survey on its fields of application

During the last decades, Ethernet progressively became the most widely used local area networking (LAN) technology. Apart from LAN installations, Ethernet became also attractive for many other fields of application, ranging from industry to avionics, telecommunication, and multimedia. The expanded application of this technology is mainly due to its significant assets like reduced cost, backward-compatibility, flexibility, and expandability. However, this new trend raises some problems concerning the services of the protocol and the requirements for each application. Therefore, specific adaptations prove essential to integrate this communication technology in each field of application. Our primary objective is to show how Ethernet has been enhanced to comply with the specific requirements of several application fields, particularly in transport, embedded and multimedia contexts. The paper first describes the common Ethernet LAN technology and highlights its main features. It reviews the most important specific Ethernet versions with respect to each application field’s requirements. Finally, we compare these different fields of application and we particularly focus on the fundamental concepts and the quality of service capabilities of each proposal
