1. End-to-End Programmability and Orchestration in 5G Networks
Monday, July 3, 14.00 – 18.00 / Room 4.1
This half-day lecture-format tutorial will explore end-to-end programmability and orchestration in 5G networks. We will provide a brief overview of enabling technologies such as 5G, SDN, NFV, P4, etc. We will then explore how programmability at different layers of the network – enabled by such technologies – can be orchestrated together to turn the networking infrastructure into an end-to-end programmable platform to better support new services and applications. We will present different aspects of orchestration across radio, transport, and cloud domains, and will overview various relevant research efforts. We will also discuss challenges and new research directions through several use cases and one demo [IEEE-NFV-SDN]. The tutorial targets researchers and industry practitioners interested in understanding the role of end-to-end programmability in 5G systems.

2. The ONOS and CORD projects
Friday, July 7, 9.00 – 12:30 / Room 0.5
This Tutorial will describe the ONOS and CORD projects. ONOS is an open source project started in 2014 at ON.Lab (Open Networking Laboratory) and hosted by The Linux Foundation. The goal of the project is to deliver a software-defined networking (SDN) OS for service providers that has scalability, high availability, high performance and APIs to make it easy to create apps and services that control the traffic in the network. Today the platform is based on a solid architecture written in Java, and has quickly matured to be feature rich and production ready. The talk will have a technical focus discussing the different aspects of the ONOS architecture, stat distribution, northbound APIs like intents, southbound protocols integration, performances, multiple use-cases and applications. During the talk there will be also a demo of the platform. The second part of the talk will cover the CORD (Central Office Re-Architectured as a Datacenter) open-source project. The CORD project brings datacenter economies and cloud agility to service providers for their residential, enterprise, and mobile customers using an open reference implementation with an active participation of the community. The reference implementation of CORD is built from commodity servers, white-box switches, disaggregated access technologies (e.g., vOLT, vBBU, vDOCSIS), and open source software (e.g., OpenStack, ONOS, XOS).This gives network operators the means to configure, control, and extend CORD to meet their operational and business objectives. The first part of the talk will outline the basic hardware and software platform of CORD and how different components of the project integrate together. The second part will describe the different use-cases, Residential-CORD, Enterprise-CORD and Mobile-CORD that focuses on 5G. The services added on top of the base platform will be outlined. The CORD reference implementation is sufficiently complete to support field trials, which will be discussed. The ONOS community has grown to include over 50 partners and collaborators (with AT&T, Verizon, Huawei, Cisco, and China Unicom among others). The newer CORD community has already more than 40 partners and collaborators (with AT&T, Verizon, Google, Radisys , Comcast, SK telecom and China Unicom among others) the partners and collaborators of both communities contribute to all aspects of the projects, from code development, to use cases and deployments.

3. Fast Packet processing in VNF using DPDK and fd.io
Friday, July 7, 9.00 – 12:30 / Room 0.6
Packet processing in the fast path involves looking up bit patterns and deciding on an actions at line rate. The complexity of these functions at Line Rate, have been traditionally handled by ASICs and NPUs. However with the availability of faster and cheaper CPUs and hardware/software accelerations, it is possible to move these functions onto commodity hardware. This tutorial will talk about the various building blocks available to speed up packet processing both hardware based e.g. SR-IOV, RDT, QAT, VMDq, VTD and software based e.g. DPDK, Fd.io/VPP, OVS etc and give hands on lab experience on DPDK and fd.io fast path look up with following sessions. 1: Introduction to Building blocks: Sujata Tibrewala 2: DPDK HASH Library Hands-on training: Saikrishna Edupuganti 3: DPDK IP Pipeline Hands-on: Muthurajan Jayakumar 4: FD.io VPP Architecture and Hands-on Training: Sergio Gonzalez Monroy
