A method for managing a transmission order in a network includes the steps of: providing an upstream host and a plurality of downstream hosts; performing a order of a plurality of data transmission events between the upstream host and the plurality of the downstream hosts; performing a first data transmission event by the upstream host to receive first data from a first downstream host; monitoring whether the upstream host receives any priority instructions from any other downstream hosts; and if a first priority instruction is received from a second downstream host during the first data transmission event, stopping the first data transmission event and performing a second data transmission event by the upstream host to receive second data from the second downstream host.
