FIG. 12 is a schematic structural diagram of a receiver according to an embodiment of the present invention. It should be understood that, the receiver 1200 in FIG. 12 can implement steps executed by the receive end in FIG. 10. To avoid repetition, details are not described herein again. The receiver 1200 in FIG. 12 includes a receiving module 1210, configured to receive a data stream by using a physical connection group. The physical connection group includes multiple physical connections and supports at least one virtual connection. A target virtual connection of the at least one virtual connection is used to transmit a service stream, and a field that is used to identify content of a timeslot resource configuration timeslot configuration table in an overhead code block transmitted over each physical connection in the multiple physical connections is used to transmit only a timeslot resource configuration timeslot configuration table currently used by each physical connection. The receiver 1200 also includes a determining module 1220, configured to determine, from total bandwidth resources of the multiple physical connections and according to timeslot configuration tables used by the multiple physical connections, a timeslot bandwidth resource that belongs to the target virtual connection. A timeslot configuration table used by each physical connection is used to indicate a virtual connection to which each timeslot bandwidth resource obtained by dividing a bandwidth resource of each physical connection belongs. The receiver 1200 also includes a restoration module 1230, configured to restore, from the data stream and according to the timeslot bandwidth resource that belongs to the target virtual connection, the service stream transmitted over the target virtual connection.
