## What I do
- Design and implement SDN architectures
- Program network behavior through controllers
- Separate control plane from data plane
- Implement network virtualization
- Create dynamic network policies
- Manage network through software APIs
- Deploy network automation with SDN
## When to use me
Use me when:
- Building programmable network infrastructure
- Implementing network virtualization
- Managing data center networks
- Creating dynamic network policies
- Requiring network-wide visibility
- Automating network operations at scale
## Key Concepts
### SDN Architecture
```
┌─────────────────────────────────────────────────────┐
│ Application Layer │
│ (Network Apps & Orchestration) │
└─────────────────────┬───────────────────────────────┘
│ Northbound API

### OpenFlow Protocol
Standard southbound protocol for SDN:
```python
# Ryu SDN Controller example
from ryu.controller import ofp_event
from ryu.controller.handler import MAIN_DISPATCHER, set_ev_cls
from ryu.lib.packet import packet, ethernet, ipv4
class SimpleSwitch(app_manager.RyuApp):
def __init__(self, *args, **kwargs):
super(SimpleSwitch, self).__init__(*args, **kwargs)
@set_ev_cls(ofp_event.EventOFPPacketIn, MAIN_DISPATCHER)
def packet_in_handler(self, ev):
msg = ev.msg
dp = msg.datapath
ofp = dp.ofproto_parser
# Install flow rule
actions = [ofp.OFPActionOutput(ofp.OFPP_FLOOD)]
self.add_flow(dp, 1, actions)
```
### SDN Use Cases
- **Data Center**: Network virtualization, tenant isolation
- **WAN**: SD-WAN for branch connectivity
- **Campus**: Centralized policy management
- **Service Provider**: Network slicing
### Controllers
- **OpenDaylight**: Enterprise, feature-rich
- **ONOS**: Carrier-grade, performance
- **Ryu**: Python, lightweight
- **ODL**: Vendor-neutral
