Abstract

See full text

A shaping algorithm for use in a queuing system in which there is no background process for detecting clock wrap around. The algorithm applies to Asynchronous Transfer Mode (ATM) applications and to the different categories of service connections specified by the ATM Forum. The algorithm is implemented by a time slotted calendar system to shape cell streams into conformance with network traffic descriptors. The calendar register is constrained to positive values to ensure valid results from the maximum functions carried out by the Algorithm. The register is divided into quadrants and the location of theoretical cell emission times relative to current and next time slots within the quadrants is used to detect clock wrap around.
