Half Day: Understanding and Deploying Virtual Networks
Instructor: Srini Seetharaman, Technical Lead for Software-Defined Networking, Deutsche Telekom
Analogous to server virtualization, Network Virtualization decouples and isolates virtual networks (i.e., tenants) from the underlying network hardware. One of the key value propositions of Software-defined Networking (SDN) is to enable the provisioning and operation of virtual networks. There are several ways of achieving this, including these two popular modes:
- Overlay-mode, where edge servers are programmed to form intelligent overlays;
- Fabric-mode, where SDN-enabled top-of-rack physical switches are controlled.
This tutorial provides an overview of both ways, and then proceeds to give hands-on experience in deploying a real overlay-based virtual network using solution from a SDN vendor.
1. Introduction to SDN
- What is SDN?
- Why SDN? — Primary value propositions
- Types of SDN solutions and key players
2. Network Virtualization theory
- What and why?
- Network overlays and Encapsulation
- OpenStack Neutron: Introduction and Integration
- L4-L7 integration and orchestration
3. SDN-based Network Virtualization
- Solution classification and deployment modes
- L2-L4 solution architectures for overlay and physical
- L4-L7 solution architectures
- Overview of solutions from popular vendors like Nicira/VMware, PLUMgrid, Big Switch, NEC, Cisco vPath, Embrane Heleos.
4. Hands-on investigation into Overlay-based Virtual Networks
- Instructor–led walk through of solution from PLUMgrid – Setup, Provisioning, Management, Integration to OpenStack
- Attendees self-walkthrough of PLUMgrid AWS – Provisioning, Management, Integration to OpenStack
5. Q&A, Open Discussion
