摘要： An apparatus and method for guaranteeing a service specific bandwidth in an Ethernet frame transmission system. In the method, memory status information of an input frame buffer and usable bandwidth information of a present Ethernet network are obtained if congestions or errors occur in the Ethernet frame transmission system. Then, different pause times by service specific priorities are set based on the memory status information and the usable bandwidth information. A MAC control frame including the pause frame is provided to the corresponding adjacent nodes. A media access control processor, if the received Ethernet frame is the MAC control frame, detects the pause times by priorities in the detected pause frame. A single processor generates drop information by priorities. A network processor drops a corresponding Ethernet frame according to the drop information by priorities, which is generated from the signal processor.
