    摘要: One embodiment provides a method for enabling class-based credit flow control for a network node in communication with a link partner using an Ethernet communications protocol. The method includes receiving a control frame from the link partner. The control frame includes at least one field for specifying credit for at least one traffic class and the credit is based on available space in a receive buffer associated with the at least one traffic class. The method further includes sending data packets to the link partner based on the credit, the data packets associated with the at least one traffic class.

    摘要: This disclosure describes enhancements to Ethernet for use in higher performance applications like Storage, HPC, and Ethernet based fabric interconnects. This disclosure provides various mechanisms for lossless fabric enhancements with error-detection and retransmissions to improve link reliability, frame pre-emption to allow higher priority traffic over lower priority traffic, virtual channel support for deadlock avoidance by enhancing Class of service functionality defined in IEEE 802.1Q, a new header format for efficient forwarding/routing in the fabric interconnect and header CRC for reliable cut-through forwarding in the fabric interconnect. The enhancements described herein, when added to standard and/or proprietary Ethernet protocols, broadens the applicability of Ethernet to newer usage models and fabric interconnects that are currently served by alternate fabric technologies like Infiniband, Fibre Channel and/or other proprietary technologies, etc.

    摘要: Techniques are described that can extend the transmission rate over cable. Multiple cables can be used to increase the transmission rate. The transmission standard applied for each cable can be an Ethernet backplane standard such as IEEE 802.3ap (2007). Data can be assigned to virtual lanes prior to transmission over a cable. Forward error correction may be applied to each virtual lane prior to transmission over cable. Forward error correction may be negotiated over a single virtual lane and then applied to all virtual lanes.
