Abstract: A traffic control method and apparatus for solving service quality degradation caused by traffic overhead in a specific node, on which traffic is concentrated in the specific node because of traffic congestion in a software defined network (SDN) environment. A traffic control method to be performed by an SDN controller of an SDN environment includes: collecting real-time traffic state information of a network; detecting traffic overhead of at least one node on the basis of the collected real-time traffic state information; determining whether network resources are available to the at least one node where the traffic overhead is detected; and changing a service level agreement (SLA)-based bandwidth allowable capacity with regard to the at least one node in accordance with available network resources.

Abstract: A high speed data serial connection interface apparatus, CPRI transmitting and receiving methods thereof are disclosed. A high speed data serial connection interface apparatus according to the present invention includes: a data transmitter configured to count a continuous NCB of 0 or 1 in an input data block, select an LSI value, and perform up scaling on data in the block in accordance with the selected LSI value to transmit the data through an optical fiber in accordance with a CPRI (common public radio interface) protocol; and a data receiver configured to receive the data transmitted by the data transmitter, restore the LSI value from the received data, and perform down scaling on the received data in accordance with the restored LSI value to restore original data.
