Abstract
A switch and a scheduling method for packet forwarding of the same are provided. The switch includes a plurality of absorb queues, a plurality of egress ports, and an absorb scheduler. Each of the egress ports includes a plurality of egress queues that are respectively connected to one of the absorb queues that are different from one another. The scheduling method includes: generating a priority state for each of the egress queues of each of the egress ports; a packet forwarding priority state of each of the absorb queues is determined according to the priority state of each of the egress queues connected thereto; and the absorb scheduler selecting one of the absorb queues to send a packet stored therein to a target egress queue of a target egress port to be sent to, according to the priority state of each of the egress queues.
