A load-balanced switch is a switch architecture which guarantees 100% throughput, (the equivalent of perfect arbitration), with no central arbitration at all, at the cost of sending each packet across the crossbar twice. Load-balanced switches are a subject of research for large routers scaled past the point of practical central arbitration.

Famous quotes containing the word switch:
“Uncritical semantics is the myth of a museum in which the exhibits are meanings and the words are labels. To switch languages is to change the labels.”
—Willard Van Orman Quine (b. 1908)
