Abstract
The Weighted Differential Scheduler (WDS) is a new scheduling discipline for accessing shared resources. The work described here was motivated by the need for a simple weighted scheduler for a network switch where multiple packet flows are competing for an output port. The scheme can be implemented with simple arithmetic logic and finite state machines. We are describing several versions of WDS that can merge two or more flows. An analysis reveals that WDS has lower jitter than any other weighted scheduler known to us.
