SDN Architecture

Control plane software is running on a general purpose server controller)The control plane is not just for network devices, but for the whole network.

The data plane is the forwarding table which is programmable. OpenFlow is the protocol between the controller and network devices.

SDN + APP Network APP

Learning Bridge: Legacy NetworkLearning Bridge Algorithm:

If the address is in the tables, forwarding.

If the address is in the tables, broadcasting except the input port.

32

Learning Bridge: SDN

33

Ryu: Simple Switch

34

Spanning Tree Protocol The Spanning Tree Protocol (STP) is a network protocol that ensures a

loop-free topology for any bridged Ethernet local area network. Broadcast storming.

Redundant links for automatic backup paths.

Protocol Operation: 1. Select a root bridge.

2. Determine the least cost paths to the root bridge.

3. Disable all other root paths.

35

Ryu: STP Lib

36

Notification of the OpenFlow message reception from the Stp class instance. STP calculation of the Bridge class instance. Status change of the port of the Port class instance and send/receive of BPDU

packets.

Ryu: FirewallUse flow entries to forward/drop the packets.
