METHOD AND APPARATUS FOR CONTROLLING A TRAFFIC SWITCHING OPERATION BASED ON A SERVICE CLASS IN AN ETHERNET-BASED NETWORK

摘要

The present invention is a service class (Class of Service: CoS) relates to a switching of a service class-specific traffic from the Ethernet (Ethernet) based network for efficient flow control of Ethernet frame control method based on and the switching device, which at least one in the process of transmitting an Ethernet frame with the at least one destination node is received from a source node to a switching control method for controlling traffic flow in the Ethernet frame, the including a predetermined priority information is specified for each class of service from the source node the method comprising: receiving an Ethernet frame, the received Ethernet frame and the process of storing in accordance with the service class to the first class of service for each separated data buffer corresponding to the priority information, the current data size, and traffic congestion stored in the data buffer process of comparing a predetermined threshold value to distinguish between the status and, if the current amount of data stored in the data buffer at least the threshold value above the the method comprising the steps of: generating a predetermined transmission interruption frame containing the service class value, the transmission stop frames through the input port of an Ethernet frame it is transmitted characterized in that it comprises the step of transmitting to the source node. ; CoS, DSCP, Ethernet, Ethernet frames, packets, switching, and traffic congestion
