Message Distribution
To minimize message traffic between components in an ALSP confederation, AIS employs a form of intelligent message routing that uses the Event Distribution Protocol (EDP). The EDP allows ACMs to inform the other AIS components about the update and interaction filters registered by their simulations. In the case of update messages, distribution of this information allows ACMs to only distribute data on classes (and attributes of classes) that are of interest to the confederation. The ABE also use this information to send only information that is of interest to the components it serves. For interaction messages, the process is similar, except that the kind parameter in the interaction message determines where the message is sent.

Famous quotes containing the words message and/or distribution:
“Here [in London, history] ... seemed the very fabric of things, as if the city were a single growth of stone and brick, uncounted strata of message and meaning, age upon age, generated over the centuries to the dictates of some now all-but-unreadable DNA of commerce and empire.”
—William Gibson (b. 1948)
“Classical and romantic: private language of a family quarrel, a dead dispute over the distribution of emphasis between man and nature.”
—Cyril Connolly (1903–1974)
