Abstract: The present invention discloses a link adjusting method and apparatus, where the method includes: increasing or reducing, by a first chip, a link between the first chip and a second chip; acquiring, by the first chip, an unchanged link between the first chip and the second chip; sending, by the first chip, an adjustment request message to the second chip, and sending, to the second chip, service data between the first chip and the second chip by using the unchanged link, so that the second chip synchronizes and aligns the link between the first chip and the second chip, and the second chip executes a service between the first chip and the second chip. The apparatus includes: an adjusting module, an acquiring module, and a sending module. The present invention may adjust a link under a circumstance that service data transmission between chips is not interrupted.

Abstract: A receiving-side chip is disclosed according to the present invention, which includes a processor, configured to acquire and execute following instructions: receiving link information sent by a sending-side chip, and enabling, according to the link information, a SerDes link to be added; receiving padding data from the added SerDes link according to a short unit frame period to acquire a synchronization word, and determining, according to the synchronization word, whether the added SerDes link has been synchronized; switching a read period of data in the added SerDes link from the short unit frame period into a long unit frame period, and aligning the data of the added SerDes link with the data of an original SerDes link; and receiving service data over the added SerDes link and the original SerDes link.
