Abstract: A TSN-based distributed antenna system including a headend unit, one or more TSN switches, and one or more remote units and a fronthaul transport network constituted by the headend unit, the TSN switch, and the remote unit is provided. The packet-based fronthaul network constituted by the headend unit, the TSN switch, and the remote unit transmits traffic in a time-deterministic manner while minimizing packet loss through Ethernet to which TSN standards are applied.

Abstract: Disclosed is an OpenFlow based distributed antenna system (DAS) policy routing method. The DAS policy routing method includes: extracting, by a DAS unit, a match field from header information of a received frame; and comparing, by the DAS unit, the extracted match field with a matching rule of a forwarding table to route according to a matching traffic transmission policy and output a frame to an output port of the DAS unit.

Abstract: Disclosed is a distributed antenna system (DAS). The DAS includes a DAS controller, which is an OpenFlow controller, and one or more DAS units in order to dynamically control a traffic transmission policy of the DAS units using an OpenFlow protocol, wherein the DAS controller generates and changes a traffic transmission policy by reflecting a traffic transmission policy change request by operator manipulation or a software-defined network supporting application and a need for changing of the traffic transmission policy according to a status of the DAS unit and a status of a port, and the DAS unit transmits received traffic to a destination according to the policy.
