Abstract: A sub-frame radial bogie comprises wheelsets, a side frame, a swing bolster, a wheelset radial device and a brake gear. Bearing adapters (41) forming the wheelset radial device are fixedly connected with the sub-frame (42) via pulling rivets (11), and each group of the bearing adapters (41) is bilaterally symmetrical in structure with a symmetry plane (A). The sub-frame (42) comprises an arm (51) and an end (52); a sub-frame connection hole (61) is arranged on the end (52); transverse positioning bosses (73) are arranged on the bearing adapters (41); and an arc groove (75) and symmetrical sub-frame connection holes (71) are arranged on a connection base (72). The bearing adapters use the same standard structure, hence, the more precise design and machining can be realized, and the cost is reduced, and meanwhile, the maintenance technique of the sub-frame is improved, and the maintenance cost is reduced.

Abstract: The present disclosure discloses a method for multi-homing path selection of a stream control transmission protocol (SCTP). The method includes the following steps of: starting quality evaluation of paths; calculating a quality evaluation value of each path; comparing the quality evaluation value of each path; and selecting a path with the highest quality evaluation value to transmit a data message. The present disclosure also discloses an apparatus for multi-homing path selection of an SCTP. By adopting the method and the apparatus, a network selects the path with the highest quality evaluation value to transmit a data message. As long as path faults affect the transmission efficiency, other path with better quality is selected for transmission, thus the capability of the network of dealing with all kinds of path faults can be improved, and the data transmission speed and quality are further improved.
