non- +"Ž blocking
A switch that provides a guaranteed talk path for every terminal; in other words, there exists a 1:1 (one-to-one) relationship between ports and time slots. Such a configuration is expensive, generally considered excessive and, therefore, unusual in all but the most intense applications scenarios, such as call center ACDs and backbone data switches. See Figure N-1. See also ACD, backbone, blocking, and call center.
The ability of a signal to reach its destination without interference or delay. In a non-blocking switch, all ports can run at full wire speed without any loss of packets or cells.
