Abstract: A packet transmission method, packet transmission apparatus, and an interconnect interface are presented, where the method includes determining, by a sending node, whether an unrecoverable failure occurs in an active link, and if an unrecoverable failure occurs in the active link, selecting, from multiple communication links, at least one standby link except the active link to send a packet to a receiving node, so that the receiving node sends the packet to a receive end of the active link. In the method, for two nodes in an interconnect system that communicate with each other using multiple Links, when it is determined that an unrecoverable failure occurs in some of the Links, packets in retransmission buffers of transmit ends of the links in which the failure is unrecoverable are sent to a standby link.

Abstract: A method for retransmitting data includes a transmitter receiving a retry request, where the retry request includes a sequence number of a first to-be-retransmitted flit. The transmitter reads data in a retry buffer based on the sequence number of the first to-be-retransmitted flit and retransmits the data, where the retry buffer includes flits of at least two types of data packets, and retransmission manners of the at least two types of data packets are different.

Abstract: The present invention discloses a switching apparatus, a switching apparatus group, a data transmission method, and a computer system, and pertains to the field of computer technologies. The switching apparatus includes: a selection circuit module, a SERDES module, and a scheduling module. The selection circuit module establishes at least (n−1) static links with each of n modes, and any two static links that are connected to the selection circuit module and that belong to different nodes are connected to each other. The SERDES module is disposed on a static link connected to the selection circuit module. The scheduling module establishes connections to the selection circuit module and each of the n nodes. The selection circuit module further establishes at least one dynamic link with each of the n nodes.
