Detailed Description

Stores an active flow entry.

This class stores and controls an active flow entry on the attached datapath element. A flow entry is unidirectional and consists of a source and a destination host identified by their respective ethernet hardware addresses. The installed flow entry on the datapath element forwards frames via the specified outgoing port. Class cflowentry_env defines the environment expected by an instance of class cflowentry. A flow entry is a soft-state entity and installs a timer upon creation
