Abstract
An asynchronous transfer mode scheduler schedules connection utilizing available bit rate (ABR) modes of traffic, unspecified bit rate (UBR) modes of traffic, variable bit rate (VBR) modes of traffic, and constant bit rate (CBR) modes of traffic. The scheduler communicates with a dynamic schedule table which includes a programmable number of slots. Each slot includes a CBR entry, a tunnel entry, and a number of VBR entries. The VBR entries store a slot tail pointer which indicates the end of a linked list. The scheduler utilizes the single bucket algorithm or dual bucket algorithm to dynamically schedule connections on future slots. The scheduler places connections using the VBR mode of traffic in a priority queue and takes the highest priority connection in the priority queue for transmission on the network.
