Network Virtualization: Details, Theory & Practice

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

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
