Classification
Classifiers are the fundamental component of an OpenFlow switch. Each flow, or row, in the flow table contains a classifier. The first flow whose classifier matches a packet becomes the active flow entry for that packet. The flow entry also contains an action set which will be applied to all packets matched. A classifier is a sequence of partial or full field match elements from various protocols. Each subsequent version of OpenFlow expands the number of protocols and fields supporting classification.
Classifier Stack
This version of OpenFlow can classify against port ID and up to 6 protocols. It is important to note that support for classifying on ARP values is not mandatory. A controller will only know if a switch supports the optional classifier for ARP, based on a FeatureRes. The feature_capabilities will indicate ARP matching is supported if the switch is capable. Classifiers installed in a switch by the FlowMod message, which carriers the classifier in the Match Structure.

This version of OpenFlow can classify against port ID, metadata, and up to 7 protocols. It is important to note that support for classifying on ARP values is not mandatory. A controller will only know if a switch supports the optional classifier for ARP, based on a FeatureRes. The feature_capabilities will indicate ARP matching is supported if the switch is capable. Classifiers installed in a switch by the FlowMod message, which carriers the classifier in the Match Structure. Additionally, this version of Openflow allows for passing information between tables via the Metadata field. A classifier can match on a maskable metadata value, which can be used to partition classification between tables.
