摘要： Systems, methods, and non-transitory computer-readable storage media for performing hierarchical routing are disclosed. The method includes identifying routes in a computer network and arranging those routes in two separate routing tables. The first routing table is stored on a first module and the second routing table is stored on a second module.

摘要： 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.

摘要： This document discusses, among other things, an example system and methods for memory expansion. An example embodiment includes receiving a memory request from a memory controller over a channel. Based on the memory request, the example embodiment includes selecting a location in memory to couple to a sub-channel of the channel and configuring the set of field effect transistors to couple the channel with the sub-channel. In the example embodiment, data may be allowed to flow between the memory controller and the location in the memory over the channel and the sub-channel.

摘要： 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.

摘要： Techniques are presented herein to facilitate higher bandwidth communications in a data center using existing multi-mode fibers and full-duplex optical communication techniques. A first device transmits to a second device a first optical signal at a first wavelength on a first optical fiber. The first optical signal carries a first portion of Ethernet traffic. The first device receives a second optical signal transmitted at a second wavelength on the first optical fiber from the second device. The second optical signal carries a first portion of Ethernet traffic. On a second optical fiber, the first device transmits to the second device a third optical signal at a third wavelength. The third optical signal carries a second portion of Ethernet traffic. The first device receives a fourth optical signal at a fourth wavelength on the second optical fiber, the fourth optical signal carrying a second portion of Ethernet.
