    • In general, in one aspect, the disclosure describes an apparatus including a receiver to receive a data packet as a plurality of data vectors over an interconnect. The interconnect includes a plurality of lanes. The apparatus also includes an error detector to detect errors in the data vectors. A buffer is used to store the data vectors received error free. A processor requests a retransmission of the packet if data vectors making up the packet are received with errors. The retransmission of the data packet includes at least a subset of the data vectors being transmitted on different lanes. An assembler reconstructs the data packet once the plurality of data vectors making up the data packet are stored in the buffer. The data packet can be reconstructed even if it was never sent correctly in a single transmission.
    • 通常,在一个方面,本公开描述了一种包括接收器的装置,所述接收机通过互连件接收数据分组作为多个数据矢量。 互连包括多个通道。 该装置还包括用于检测数据向量中的错误的错误检测器。 缓冲区用于存储接收到的数据向量无错误。 如果接收到构成分组的数据向量,则处理器请求重新发送分组。 数据分组的重传包括在不同车道上发送的数据矢量的至少一个子集。 一旦构成数据包的多个数据向量被存储在缓冲器中,汇编程序重构数据包。 即使在单个传输中从未正确发送数据包,也可以重建数据包。
