Method for transmitting service stream in flexible ethernet and apparatus
摘要
說明書
According to a third aspect, a transmitter is provided. The transmitter includes an obtaining module, configured to obtain a to-be-transmitted service stream. The service stream is to be transmitted using a target virtual connection supported by a physical connection group between a transmit end and a receive end. The physical connection group includes multiple physical connections and supports at least one virtual connection, and the target virtual connection is any one of the at least one virtual connection. The transmitter also includes a determining module, 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 transmitter also includes a transmission module, configured to transmit the service stream to the receive end using the timeslot bandwidth resource that belongs to the target virtual connection. An overhead code block transmitted over each physical connection includes a first field. The first field indicates an identifier of the timeslot configuration table used by each physical connection. The overhead code block transmitted over each physical connection further includes fields used for a management channel. The management channel is used to, when the timeslot configuration table used by each physical connection changes, transmit content of a changed timeslot configuration table.
