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.
