摘要： A stereo encoding method and apparatus, and a stereo decoding method and apparatus are disclosed. The stereo encoding method includes: performing downmix processing on a left channel signal of a current frame and a right channel signal of the current frame, to obtain a primary channel signal of the current frame and a secondary channel signal of the current frame; and when determining that a frame structure similarity value falls within a frame structure similarity interval, performing differential encoding on a pitch period of the secondary channel signal by using an estimated pitch period value of the primary channel signal, to obtain a pitch period index value of the secondary channel signal, where the pitch period index value of the secondary channel signal is used to generate a to-be-sent stereo encoded bitstream.

摘要： A multichassis link aggregation method includes receiving, by a first network device, n pieces of second information of n second network devices. The first network device and the n second network devices are in a multichassis link aggregation group (MC-LAG), n is an integer greater than or equal to 1, the n pieces of second information include n second port keys, and the n pieces of second information are in one-to-one correspondence with the n second port keys. The method also includes determining, by the first network device, a third port key based on a first port key of the first network device and the n second port keys. The third port key is an MC-LAG configuration parameter of the first network device.
