Dynamic link adjustment method and link managing device

摘要

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.

主权项

1. A link adjustment method, comprising:
receiving, by a receiving side, link information from a sending side; enabling, by the receiving side according to the link information, a Serializer/Deserializer (SerDes) link to be added; receiving, by the receiving side, padding data from the sending side according to a short unit frame period over the added SerDes link, wherein a synchronization word is added into the padding data; searching, by the receiving side according to the short unit frame period, for the synchronization word in the added SerDes link, and determining, according to the synchronization word, whether the added SerDes link is synchronized; when the receiving side determines that the added SerDes link has been synchronized, feeding back, by the receiving side, a response, indicating that the added link has been synchronized to the sending side; switching, by the receiving side according to alignment words inserted to an original SerDes link and the added SerDes link, 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 data of the original SerDes link; receiving, by the receiving side, service data from the sending side according to the long unit frame period over the added SerDes link.
