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.
In the field of telecommunications, a Clos network is a kind of multistage circuit-switching network which represents a theoretical idealization of practical, multistage switching systems. It was invented by Edson Erwin [ 1 ] in 1938 and first formalized by the American [ 2 ] engineer Charles Clos [ 3 ] in 1952.
Head-of-line blocking example: The 1st and 3rd input flows are competing to send packets to the same output interface. In this case if the switching fabric decides to transfer the packet from the 3rd input flow, the 1st input flow cannot be processed in the same time slot.
For data center architecture, QFabric creates a single logical switch that connects the entire data center rather than tiers of multiple access aggregation and core switches. The reason why this can improve performance is that, instead of going through multiple tiers of switches in a traditional network, packets only get through the ...
While the term "fabric" has also been used in association with storage area networks and with switched fabric networking, the introduction of compute resources provides a complete "unified" computing system. [citation needed] Other terms used to describe such fabrics include "unified fabric", [4] "data center fabric" and "unified data center ...
In 2013 and 2014 SPB was used to build the InteropNet backbone with only one-tenth the resources of prior years. [13] During Interop 2014 SPB was used as the backbone protocol which can enable software-defined networking (SDN) functionalities. [14] [15] The 2014 Winter Olympics were the first "fabric-enabled" Games using SPB "IEEE 802.1aq ...
Fabric Connect's aim is to provide network-wide, end-to-end, multi-layer virtualization. A network virtualization capability, based on an enhanced implementation of the IEEE 802.1aq Shortest Path Bridging (SPB) standard, Fabric Connect offers the ability to create a simplified network that can dynamically virtualize elements to efficiently provision and utilize resources, thus reducing the ...
