Switched fabric or switching fabric is a network topology in which network nodes interconnect via one or more network switches [1] (particularly crossbar switches).Because a switched fabric network spreads network traffic across multiple physical links, it yields higher total throughput than broadcast networks, such as the early 10BASE5 version of Ethernet and most wireless networks such as Wi-Fi.
Virtual Cluster Switching (VCS) fabric technology is a Layer 2 proprietary Ethernet technology from Brocade Communications Systems, later acquired by Extreme Networks. [1] It is designed to improve network utilization, maximize application availability, increase scalability, and simplify the network architecture in virtualized data centers.
A time-slot interchange (TSI) switch is a network switch that stores data in RAM in one sequence, and reads it out in a different sequence. It uses RAM, a small routing memory and a counter. Like any switch, it has input and output ports. The RAM stores the packets or other data that arrive via its input terminal.
When the Clos network was first devised, the number of crosspoints was a good approximation of the total cost of the switching system. While this was important for electromechanical crossbars, it became less relevant with the advent of VLSI , wherein the interconnects could be implemented either directly in silicon, or within a relatively small ...
IEEE 802.1aq is an amendment to the IEEE 802.1Q networking standard which adds support for Shortest Path Bridging (SPB).This technology is intended to simplify the creation and configuration of Ethernet networks while enabling multipath routing.
It is designed to be scalable and uses a switched fabric network topology. Between 2014 and June 2016, [ 1 ] it was the most commonly used interconnect in the TOP500 list of supercomputers. Mellanox (acquired by Nvidia ) manufactures InfiniBand host bus adapters and network switches , which are used by large computer system and database vendors ...

The architecture enables scalability by increasing the number of Line Card Chassis and/or Fabric Card Chassis. In both single- and multi-chassis configurations, the CRS switch fabrics are based on a three-stage Benes architecture. In a single-chassis system, the three switching stages—S1, S2, and S3—are all contained on one fabric card.
