A method and apparatus for ensuring QoS in a synchronous Ethernet bridge are disclosed, in which a classifier classifies an ingress packet according to a PHB mapped to a DSCP value of the packet and provides the classified packet to one of a predetermined synchronous packet queue and a predetermined asynchronous packet queue, a buffer queue with a plurality of queues mapped to priority levels buffers the classified packet, a marker marks the buffered packet as a synchronous packet or, if the buffered packet is an asynchronous packet, marks the packet in a predetermined format corresponding to a priority level of the packet, and a synchronous Ethernet scheduler schedules the marked packet.
