Abstract: A device and method related to processing an optical signal so as to compensate nonlinear distortions of optic fibers are provided. The method includes: generating a first signal by equalizing the optical signal using a first DBP algorithm; generate a first sequence of LLRs by demapping and deinterleaving the first signal; generating a first sequence of bits by iteratively decoding the first sequence of LLRs for a first number of iterations; generating a sequence of QAM symbols by mapping and interleaving the first sequence of bits; generating a second signal by equalizing the first signal based on the sequence of QAM symbols using a second DBP algorithm; generating a second sequence of LLRs by demapping and deinterleaving the second signal; and generating a second sequence of bits by iteratively decoding the second sequence of LLRs for a second number of iterations.

Abstract: A signal pre-compensation method is provided. In the method, at least one target frequency subband is determined from a plurality of frequency subbands of a first optical signal and an optical signal of the at least one target frequency subband in the first optical signal is demodulated based on the at least one target frequency subband. A first electrical signal is obtained after demodulation, and a pre-compensation parameter is updated based on the at least one target frequency subband, the first electrical signal, and a second electrical signal. Herein the pre-compensation parameter is used to perform signal pre-compensation on the second electrical signal, and the first optical signal is generated after the pre-compensation is performed on the second electrical signal.

Abstract: Embodiments of this application disclose a congestion control method and a related device. A Transmission Control Protocol offload engine TOE sends a congestion control notification to a central processing unit CPU, where the congestion control notification instructs the CPU to obtain a target parameter, and the target parameter is used by the CPU to generate a congestion control calculation result. The TOE obtains the congestion control calculation result returned by the CPU, where the congestion control calculation result includes a congestion control window value. The TOE sends a packet based on the congestion control window value. In this application, the TOE and the CPU implement congestion control together. When a new congestion control algorithm emerges, the new congestion control algorithm may be applied without changing a structure of the TOE. Therefore, in this application, an upgrade period of the congestion control algorithm can be shortened, and flexibility can be improved.
