Abstract:
1. An apparatus for multi-homing path selection of a Stream Control Transmission Protocol (SCTP), comprising: a calculation module, a comparison module and a path selection module; wherein the calculation module is configured to start quality evaluation of paths, calculate a quality evaluation value of each path, and transmit the quality evaluation value of each path calculated to the comparison module; the comparison module is configured to, after receiving the quality evaluation value transmitted by the calculation module, compare the quality evaluation value of each path, and transmit a path with a highest quality evaluation value to the path selection module; and the path selection module is configured to select the path with the highest quality evaluation value to transmit a data message after receiving the path with the highest quality evaluation value transmitted by the comparison module; wherein when two or more paths have same quality evaluation values and paths with the same quality evaluation values comprise a preferred path, the path selection module firstly selects the preferred path to transmit a data message, and then selects a current path to transmit a data message, and finally selects other path to transmit a data message; when two or more paths have same quality evaluation values and paths with the same quality evaluation values do not comprise the preferred path, the path selection module firstly selects the current path to transmit a data message, and then selects other path to transmit a data message.
