PARALLEL SERVICE-RATE CONTROLLERS IN ATM SWITCHES

摘要

Techniques of service-rate controls in ATM switches are described, andapparatus for their implementation are devised. The techniques fall in twocategories: frequency domain controls, and time-domain controls. Theregulators control the service rate on a per-class basis or on a per-connection basis. Some class regulators operate at very high speeds of theorder of several gigabits per second and cover a medium number of classes, 32for example. Other regulators operate at high speeds of the order of several-hundred megabits per second, and cover a very large number of classes, e.g.,10,000. A compound regulator which combines both types of regulators is alsodescribed. The compound regulators extend the range of controllable classesconsiderably, covering some 200,000 classes. The main advantages of theregulators of the invention are simplicity, robustness, and high performance.
