StrideSched
StrideSched — Click element; pulls from stride-scheduled inputs
StrideSched(TICKETS0, ..., TICKETSN-1)
Ports: 1 or more inputs, 1 output
Processing: pull
Has one output and N inputs. Performs simple packet-based stride scheduling, assigning TICKETSi to input i for each input.
Each time a pull comes in on the output, it pulls on its inputs in the order specified by the stride scheduling queue, until all inputs have been tried or one produces a packet. If an input does not produce a packet, it is not tried again in the current round (for the current pull on the output) even if it has a very short stride. This minimizes overhead and ensures that an input that produces a packet, if any, is found as soon as possible, consistently with the stride scheduler ordering.
The inputs usually come from Queues or other pull schedulers. StrideSched uses notification to avoid pulling from empty inputs.
- tickets0...ticketsN-1 (read/write) — Returns or sets the number of tickets for each input port.
