A packet switch includes a pipeline scheduler for scheduling packets according to a credit-based flow control protocol. A credit update pipeline stage initializes available credits for egress ports of the packet switch. A request pipeline stage generates packet requests for packets based on the available credits. A grant pipeline stage selects packets based on the ports requests and the available credits, and generates port grants for the selected packets. Additionally, the credit update stage updates the available credits based on the port grants. The packet switch routes the selected packets from ingress ports of the packet switch to the egress ports based on the port grants. In some embodiments, ingress ports generate enqueue requests based on the packets, an enqueue pipeline stage generates enqueue states based on the enqueue requests, and the request pipeline stage selects packets for routing based on the enqueue states and the available credits.
