Eq Match

Read Match

Show Match

matchAny :: Match

A match that matches every packet.

isExactMatch :: Match -> Bool

Return True if given Match represents an exact match, i.e. no wildcards and the IP addresses' prefixes cover all bits.

getExactMatch :: PortID -> Get Match

Utility function to get an exact match corresponding to a packet (as given by a byte sequence).

frameToExactMatch :: PortID -> EthernetFrame -> Match

frameToExactMatchNoPort :: EthernetFrame -> Match

ofpVlanNone :: Integer

matches :: (PortID, EthernetFrame) -> Match -> Bool

Models the match semantics of an OpenFlow switch.
