IEC 61850: Principle operation of GOOSE messages
The Generic Object Oriented Substation Event (GOOSE) class model is used to
distribute input and output data values between IEDs on bay level (in horizontal
direction) through the use of multicast services. GOOSE messages enable fast
transmission from a publisher to one or several subscribers (receivers).
GOOSE messages are unidirectional, send only messages which request an
application specific method to secure that the sender and the receiver of the message
operate safely. This implies that the receiver of the GOOSE message distributes also
GOOSE messages and closes the loop for communication (request – respond on
application level).
