Abstract: A network system includes a first network device, a second network device, and a third network device. The first network device is configured to: obtain a first route advertisement message, where the first route advertisement message includes a first route prefix; and obtain a second route prefix based on the first route prefix, where the second route prefix corresponds to a first network slice, and the second route prefix is a subnet prefix of the first route prefix. The first network device advertises a second route advertisement message to the second network device, where the second route advertisement message includes the second route prefix.

Abstract: A packet sending method and a related device are disclosed. The method includes: A network device obtains a first packet, where an internet protocol extension header of the first packet includes a first identifier, and the first identifier indicates a service requirement corresponding to the first packet. The network device determines, based on the first identifier and a second identifier, path indication information corresponding to the first packet, where a destination address of the first packet includes the second identifier, and the path indication information herein includes one or more of a network slice identifier and a segment identifier list. The network device updates the first packet based on the path indication information to obtain a second packet, and sends the second packet.

Abstract: An error correction method and a time-interleaved analog-to-digital converter (TIADC) are provided. The method is applied to a TIADC that includes a plurality of analog-to-digital converters (ADCs), and the method includes: determining whether a current value of a codeword of a first ADC in the plurality of ADCs is within a preset range; when the current value of the codeword of the first ADC is not within the preset range, adjusting a plurality of codewords that are in a one-to-one correspondence with the plurality of ADCs; and controlling a clock frequency division circuit to generate, by using a plurality of adjusted codewords, a plurality of sampling clocks that are in a one-to-one correspondence with the plurality of ADCs. In embodiments of this application, a sampling time-period skew existing between ADCs may be adjusted by adjusting codewords corresponding to the ADCs.

Abstract: A communication network, comprising a video server, adapted to generate a multicast video signal, and a first router is provided. The communication network is operated by a first communication provider. The first router is adapted to receive the multicast video signal, generate a plurality of unicast video signals from the multicast video signal, and provide each of the plurality of unicast video signals to one of a plurality of user devices, connected to a first further communication network, through at least a first further router, which is part of the first further communication network. The first further communication network is operated by a second communication provider.
