Overview

Software-defined Networking (SDN) is a new approach to designing, building and managing networks. The goal of Network Virtualization (NV) is to simplify, optimize, and enhance the network by creating logical networks that are decoupled from the underlying physical hardware. Network Functions Virtualization (NFV) simulates hardware platforms, such as firewall or storage, using software components. This allows the usage of “off the self” computing platforms and therefore cost savings.
The course outlines the key building blocks, interfaces, practical approaches and applicable solutions for SDN, network virtualization and NFV, how these principles, architectures and protocols may be used to deploy, monitor and manage Virtual Machines and Containers to host Virtual Network Functions (VNFs).
We discuss key use cases and Network Transformation strategies for Tier-1 and Tier-2 Operator environment, and architecture considerations.
Finally, the course will provide a 2/3 day workshop utilising a number of the key SDN & NFV components discussed during the week, including: Hypervisors, Network Virtualisation, SDN Controllers; and a variety of south-bound interfaces for Operator environments focusing on NETCONF / YANG, with introductions to other South-bound Interfaces including: OVSDB, OpenFlow, and PCEP.

Objectives

  • Understand the fundamental building blocks and technology, northbound, southbound, east and west.
  • Investigate the standards ecosystem, and how it is relevant to your or your customers' networks, as we explain the work from SDOs such as ONF, IETF, ETSI NFV ISG, MEF, TM Forum, Open Daylight. Understand why standardization is shaping the future and which are the key alliances you need to build.
  • Explore current uses such as SD-WAN, vCPE, vEPC, load balancers, virtualized Firewalls, BGP routing.
  • Compare and contrast differing vendor solutions from Cisco, Juniper, Huawei, Nokia Networks and more. Who is more Open, who is less Open, why might you choose one approach over another based on your or your customers legacy network and future services you want to deploy.
  • Get detailed information on REST, NETCONF and YANG modelling.
  • Review deep level detail on OpenFlow.
  • Understand hypervisors and the various virtualization approaches in the market.
  • Consider how use cases will change on roadmap towards full-blown SDN.
  • Consolidate your new knowledge with a Hands-On workshop implementing an SDN Controller (POX, but can be swopped for ODL/ONOS) from scratch using Open components.
  • Examine how a Python script populates network elements
  • Perform protocol analysis on the OpenFlow exchanges you have just created!

Target Audience
