Abstract: The alternate destination redirection (ADR) feature (102) of telephone switching systems (101) or an equivalent is used to implement a “post-route” routing architecture having the benefits of a “pre-route” routing architecture in a network ACD (FIG. 1). The ADR feature is administered in the network (100) for individual ACD systems and individual call types at each ACD system to identify another ACD system as an alternative destination for calls of the individual call type rejected by the individual ACD system. The network distributes (302) calls to the plurality of ACD systems (110-112) on a basis (e.g., fixed percentage, round-robin) that does not require the network to know the status of the individual ACD systems. Upon having a call of an individual type routed thereto, an individual ACD system checks (304) the status of the ACD system that is administered as the alternative destination for its rejected calls of the individual type.

Abstract: Methods are disclosed for the adaptive control of windows and rates in networks. A periodic, one-bit feedback signal is combined with systematic damping and control of a gain signal to achieve a minimum bandwidth and a fair share of excess available bandwidth among virtual circuits in the network in a timely manner. The methods are demonstrated using a First-Come-First-Served service discipline, a Weighted Round-Robin service discipline, or a combination of the two disciplines.
