摘要： This invention discloses a multimode interconnection interface controller for a converged network, which comprises a SERDES element responsible for serial/parallel conversion, a LANE_TXCLK element responsible for generating a transmit clock, a SERDES initialization element responsible for link training and rate negotiation, and a PCS_EB coding element and an PCS_AF coding element responsible for physical layer coding of messages. The link training and rate negotiation are completed automatically via the shared SERDES initialization element. More universality and flexibility are provided for interconnection chip design by the PCS_EB coding element. The PCS_AF coding element is provided to reduce message penetration delay. The multimode interconnection interface controller is integrated in a single chip. Through flexible configuration, the single chip can meet transmission requirements of dedicated high speed networks and Ethernet networks. The multimode interconnection interface controller also supports interconnection of data center Ethernet and high performance computing high speed network.

摘要： The invention provides a converged network interface card, a message coding method and a message transmission method thereof. The converged network interface card comprises a PCIE host interface processing module, a high speed network card core logic, a crossbar switch XBAR, an Ethernet network card core logic, an Ethernet message dicing/slicing module, a physical layer, a high speed network/Ethernet message conversion module EoH, and a high speed network/Ethernet configurable network port. The invention supports customized high speed interconnection interface and a standard Ethernet interface on a set of network hardware, and supports three working modes on a set of physical hardware (high speed network mode, Ethernet mode and EoH mode transmitting Ethernet messages over the high speed network), implements seamless compatibility between the high speed network/Ethernet, and flexibly supports multimode applications such as scientific computing and cloud computing.

摘要： This invention discloses a hierarchical switching fabric and deadlock avoidance method for ultra high radix network routers. The hierarchical switching fabric comprises a network-on-chip and K multi-port components. The multi-port component comprises a port module configured to receive packets by a high speed serializer/deserializer, code and format the packets, send the packets to a corresponding hyper packet module after coding and format conversion, and send the packets sent by the hyper packet module to the network; and the hyper packet module configured to perform protocol processing for the received data link level packets, discard illegal packets, forward legitimate packets to the network-on-chip, perform data error correcting, format conversion and channel mapping for the packets received from the network-on-chip, and send the packets to the corresponding port module.
