Practical Software-Defined Networking: 2 SDN and OpenFlow Foundations

Learn the fundamentals of software-defined networking and OpenFlow, the SDN communications protocol.

1. SDN and OpenFlow Flows

• SDN fundamentals: OpenFlow theory
• OpenFlow forwarding
• Proactive versus reactive flow entries
• Demo: OpenDaylight (ODL) and Mininet
• Demo: OpenFlow flow tables
• Demo: OpenFlow, LLDP, Layer 2 learning switch
• Demo: Four-switch topology
• Demo: Single switch with 10 hosts
• Demo: Single switch, four hosts, OpenFlow 1.3
• Demo: HPE VAN SDN Controller, Flow Maker Deluxe
• Demo: SDN HP Flow entries

2. SDN and OpenFlow Architectures

• SDN architecture
• OpenFlow switch
• Traffic matching
• Demo: Add flows
• OpenFlow ports
• Packet ingress port
• OpenFlow physical ports
• OpenFlow logical and reserved ports
• OpenFlow-only switches versus OpenFlow-hybrid switches
• NORMAL port: OpenFlow and normal forwarding a VLAN
• Demo: Hybrid OpenFlow

3. What Happens When a Controller Fails?

• What happens when a controller fails?
• Demo: NORMAL forwarding in OpenFlow network, controller failure
• Demo: Fail secure, controller failure
• Demo OpenDaylight and Mininet fail secure
