ICIN 2024 Tutorials

Tutorial #1

Title: Setting up a Reinforcement Learning pipeline for a Telco Core Network
Duration: 3.5 hours with break

Abstract: This tutorial aims to describe how to implement a Reinforcement Learning (RL) pipeline using an Open Source Core Network like the Magma project as the environment. It details the steps required for such an integration: framing the problem according to RL, automating the deployment of the platform on a Cloud Infrastructure using Infrastructure-as-Code, automation of the actions on the platform, collection of the state of the environment through the monitoring tools. The tutorial will use the autoscaling of network functions as a use case for demonstration, showing how a RL algorithm can learn how to scale in or out the number of deployed instances automatically according to the traffic.
The tutorial will show how to implement a RL algorithm such as Deep Q- Learning, how to run experiments and how to analyze the results. It will also detail lessons learned in the process.

Tutorial #2

Title: Recent advances in Container Orchestration: Network-Aware Scheduling in Container Clouds
Duration: 3.5 hours with break

Abstract: Containers have revolutionized application deployment and life-cycle management in current cloud platforms.
Applications have evolved from single monoliths to complex graphs of loosely-coupled microservices aiming to improve deployment flexibility and operational efficiency. Nonetheless, the efficient orchestration of containerized applications is still challenging due to their complex inter-dependencies. Scheduling policies in popular container orchestration platforms mainly aim to increase the resource efficiency of the infrastructure, which is insufficient for latency-sensitive applications demanding low latency between dependent microservices. This tutorial provides an overview of application scenarios and methodologies to address the efficient orchestration of containerized applications. After that, the tutorial provides a practical vision of network-aware scheduling via the developed Diktyo framework 1,2 for the popular Kubernetes (K8s) platform. Diktyo determines the placement of dependent microservices focused on reducing the application’s end-to-end latency. The tutorial includes a live-demo showing the benefits of Diktyo by deploying typical containerized applications. Diktyo is open-sourced and hosted in the K8s scheduling community as an alternative scheduler. Lastly, lessons learned alongside future trends in container scheduling are outlined.

Tutorial #3

Title: Green NFV: framework and enablers for energy savings in telecom network deployments
Duration: 1.5 hours

Abstract: Growing number of users and ever-increasing data-intensive mobile applications are causing continuous increase in the data traffic to be handled by telecommunication networks. This growth has a direct relation with carbon footprint of telecom network deployments. To meet the goals of carbon neutrality, it becomes paramount to make the network deployments greener and energy efficient.
Network functions virtualization (NFV) technology with its inherent properties, like virtualization, infrastructure sharing, demand-based scaling of network functions and services, can act as an enabling technology in reducing carbon footprint of large-scale telecom deployments. The sophisticated management and monitoring framework offered by the NFV Management and Orchestration (NFV- MANO) system can play a vital role in ensuring energy efficiency objectives of telecom network providers.

The goal of this tutorial is:
1. To describe NFV use cases showcasing energy saving potential in Telco deployments
2. To highlight the key issues and potential solutions related to energy consumption, energy-efficient design and management, metrics collection and monitoring
3. To explore the features and capabilities of NFV MANO system in view of energy efficiency requirements.

At the end of the proposed 90-minute tutorial, the audience is expected to have an effective understanding of energy efficiency support in NFV.

Tutorial #4

Title: Enabling Networking Technologies for High Performance Computing
Duration: 1.5 hours

Abstract: Two converging trends motivate this tutorial: the massive amount of data center computation and the scale of these operations, as well as the deployment of reliable distributed storage systems. Indeed, with machine learning and artificial intelligence workloads becoming ubiquitous, there is a strong need for data interconnects and networking protocols that allow these workloads to be distributed over multiple processing nodes, to query databases, process the results and then the results being aggregated back to the application. This has pushed some high-performance requirements and new solutions onto the networking layer. Virtualization, softwarization and containerization impact data center networks as well.
This tutorial provides a deep dive into the networking layer for these types of workloads. It will focus on the networking layer to support fast transport of data for time sensitive applications. We will survey the state of the art in networking technologies used for high performance computing, and will describe the most relevant ones.
The tutorial will describe the need and emerging use cases for networking technology to efficiently support RDMA, RPCs, and will describe other efforts such as DetNet for time-sensitive networking.
