[2-day course, Euro 2,350.- (net) per participant]

Course Description

Chapter 1: IT meets Telecom

  • The Ideas of NFV (Network Function Virtualization)
    COTS-Hardware / Network Elements as Software / Virtualization in-between the two

  • The Ultimate Target of NFV on the Radio Side: C-RAN
    Concept / State of Implementation / ssues

  • Network Function Virtualization in Context
    … with SDN, cloud operation and virtualization in the PC-world / NFV vs SDN (Software Defined Networking)

  • Hands in the Mud: SDN in Practice
    Mininet Virtual Network Setup on your UBUNTU-Machine / Setting up this Network in UBUNTU / Reviewing the Network Configuration / Generating HTTP-Traffic / Reaction of the vSwitch upon the HTTP-Traffic / Wireshark Logfile of the OpenFlow Traffic

  • Virtualization in the PC-World
    Virtual Machines and Hypervisors / Application of Virtualization on a PC

  • The Cloud Business
    IaaS (Infrastructure as a Service) / SaaS (Software as a Service) / PaaS (Platform as a Service)

  • Targets, Consequences and Challenges of NFV
    Commercial Targets / Other (still monetary-driven) Targets / Challenges and Consequences

Chapter 2: NFV Architecture explained

  • The ETSI-based ISG (Industry Specification Group)
    Introduction / Time Table and History


  • Example: The EPC as virtualized Network
    The VNF as basic Entity / Virtualization Layer / Hardware Resources

  • NFV Reference Architecture
    VNF-Domain / MANO-Domain / NFVI-Domain

  • More Details on the VNF-Domain
    VNF with single VNFC / VNF with multiple VNFCs / The VNF-Descriptor (VNFD) / Hardware Dependencies

  • Communication between VNFCs
    Option 1: Serial Bus / Option 2: Hardware Switch / Option 3: Vswitch / Option 4: Through (v)NICs and across Networks

  • More Details on the VNFI-Domain
    General Remarks / The Hypervisor Domain / The Compute and Storage Domains / The Network Domain / Virtual Networking Resources (not SDN) / Operation of vSwitch

  • More Details on the MANO-Domain
    Orchestrator / Repositories / VNFM (VNF Manager) / VIM / WIM / VIM: Tasks and Functions / Example: Instantiation of a VNF / Practical Exercise: Relating Messages to Interfaces

Chapter 3: Setup and Operation of virtualized Networks

  • Configuration Virtualized Network Setup (C-RAN and EPC)
    From Network Service (NS) to VNFFG and NCT

  • Introducing the Codex of NFV
    NS (Network Service) and NSD / (VNF, VNFC, PNF, VNFD VNFCD, and PNFD) / Virtual Links and VLD / Connection Points (CP) / VNFFG

  • VLD-Examples
    E-TREE, E-LAN and E-LINE

  • NFPD- and VNFFGD-Examples
    Control Plane / User Plane

  • VNF Scaling and Load Balancing
    Scale Up/Down vs Scale Out/In / Auto Scaling and On-demand Scaling / Management based Scaling

  • Implementation Example
    KVM (Kernel-based Virtual Machine) / DPDK (Data Plane Development Kit) / SR-IOV and PCIe (Single Root Input/Output Virtualization / Peripheral Component Interconnect express) / OpenStack / OpenDaylight / Open vSwitch

Chapter 4: Optimization and Acceleration

  • Reviewing Interrupt Methods and their Impact on Virtualization
    Interrupt types, virtual interrupts, interrupt issues with virtualization, interrupt operation using hypervisors, ...

  • Memory Access and NUMA

    General description of memory access and memory sharing, influence on processing speed, NUMA and the related benefits, ...

  • Acceleration Options

    VNFD options for acceleration, typical examples like , ...

  • MANO-Descriptors with Acceleration Descriptors

    Examples of VNFD, VDU with different acceleration descriptors

Chapter 5: Scenarios and KPI-Measurements

  • Scaling Up/Down and Out/In Scenarios

  • KPI-Communication between VNF and EMS

  • SW/HW Outage VNF: Reaction of the System
