CL-GSERVER.ROUTER
ROUTER → ... → T
A router combines a pool of actors and implements the actor-api protocol. So a `tell', `ask-s' and `ask' is delegated to one of the routers routees. While a router implements parts of the actor protocol it doesn't implement all. I.e. a router cannot be `watch'ed. A router `strategy' defines how one of the actors is determined as the forwarding target of the message.
