    Abstract: A multi-stage network switch comprises a plurality of ingress port subsystems each comprising one or more ingress ports configured to receive packets. The switch also comprises a plurality of unscheduled crossbar switching elements connected to the ingress port subsystems that are configured to receive one or more packets from at least one of the ingress port subsystems. The switch further comprises a plurality of egress port subsystems each comprising a memory and a plurality of egress ports. The memory comprises at least one shared egress buffer configured to receive any packets forwarded by the crossbar switching elements from the ingress port subsystems directed to the egress port subsystem, and the egress ports are configured to transmit the packets received in the shared egress buffer.

    Abstract: An apparatus, system and method for facilitating higher bandwidth communication in a data center using existing multi-mode fibers. A first transceiver within a first device transmits Ethernet traffic to a second device over first and second optical fibers and receives return optical signals over the same first and second optical devices. By varying the wavelengths between the transmitted and received optical signals, the same optical fibers can be used to both transmit and receive optical signals. A second transceiver within the same housing as the first transceiver performs the same function. In this fashion, one device can be coupled to four bidirectional optical fibers, each transmitting and receiving optical signals at 20 Gbps.

    Abstract: The present invention provides methods and devices for implementing a Low Latency Ethernet (“LLE”) solution, also referred to herein as a Data Center Ethernet (“DCE”) solution, which simplifies the connectivity of data centers and provides a high bandwidth, low latency network for carrying Ethernet and storage traffic. Some aspects of the invention involve transforming FC frames into a format suitable for transport on an Ethernet. Some preferred implementations of the invention implement multiple virtual lanes (“VLs”) in a single physical connection of a data center or similar network. Some VLs are “drop” VLs, with Ethernet-like behavior, and others are “no-drop” lanes with FC-like behavior. Some preferred implementations of the invention provide guaranteed bandwidth based on credits and VL. Active buffer management allows for both high reliability and low latency while using small frame buffers. Preferably, the rules for active buffer management are different for drop and no drop VLs.
