Abstract: In a scenario of a flexible Ethernet, the number of Ethernet frame streams received by an Ethernet interface of a receiver and a bit width of each Ethernet frame stream may need to be adjusted. A corresponding scrambling circuit is disposed for each data segment in the Ethernet frame streams, so as to separately perform scrambling on each data segment, where the number of bits of each data segment is M. Furthermore, X scrambling circuits corresponding to X data segments in a first Ethernet frame stream may separately calculate scrambling results of the X data segments. Therefore, if an adjusted bit width of each Ethernet frame stream is an integral multiple of M, a corresponding number of scrambling circuits may be reconfigured to perform scrambling on each adjusted Ethernet frame stream.
