Physical Ports

Ingress

OpenFlow packets are received on an ingress port, processed by the OpenFlow pipeline. The packet ingress port is a property of the packet throughout the OpenFlow pipeline and represents the OpenFlow port on which the packet was received into the OpenFlow switch

Y

Y

Y

Y

Output

The OpenFlow pipeline can decide to send the packet on an output port using the output action (see 5.9), which defines how the packets goes back to the network

Logical Ports

Logical ports are switch defined ports that don't correspond directly to a hardware interface of the switch

Logical ports are higher level abstractions that may be defined in the switch using non-OpenFlow methods

LOCAL

Represent the switch's local networking stack. Can be used as an ingress port or as an output port

Y

Linux networking stack

The local port enables remote entities to interact with the switch via the OpenFlow network, rather than via a separate control network. it can be used to implement an in-band controller connection
