A connection is the interface of a conversation to the dagents. Information comes into a conversation over a connection and information is returned to dagents over a connection. The particular dagents, at any one time, talking or listening on a connection, may be dynamic. A connection is bi-directional and may have performance requirements governed by a contract.
