    Description copied from class: Protocol
    
    An event is to be sent down the stack. A protocol may want to examine its type and perform some action on it, depending on the event's type. If the event is a message MSG, then the protocol may need to add a header to it (or do nothing at all) before sending it down the stack using down_prot.down().

    Description copied from class: Protocol
    
    A message is sent down the stack. Protocols may examine the message and do something (e.g. add a header) with it before passing it down.
