Abstract
A system and method for scheduling communications from a communication interface. Each of multiple send queues is associated with a destination and assigned to a logical communication channel. A list of stalled queues identifies those send queues for which a constraint restricts scheduling. When a queue is to be selected for service, a scheduler first attempts to find a member of the stalled queues list that is no longer stalled (e.g., any constraints were satisfied). Such a queue is selected for service if it exists. If there is no such queue, then all logical channels are examined and, from a list of send queues assigned to a selected logical channel, a send queue is selected for servicing. After a queue is scheduled from the stalled queues list, the list of queues assigned to its logical channel is adjusted (e.g., to place the queue at the tail of the list).
