Switched Fabric or switching fabric is a network topology in which network nodes interconnect via one or more network switches (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, or most wireless networks such as Wi-Fi.
Extending switch fabric processing to network interface cards
An example system comprises a plurality of servers comprising respective network interface cards (NICs) connected by physical links in a physical topology, wherein each NIC of the plurality of NICs comprises an embedded switch and a processing unit coupled to the embedded switch; and an edge services controller configured to program the processing unit of a network interface card of the plurality of network interface cards to: receive, at a first network interface of the NIC, a data packet from a physical device; based on the data packet being received at the first network interface, modify the data packet to generate a modified data packet; and output the modified data packet to the physical device via a second network interface of the NIC.

Multipath routing for switching fabric
A switching fabric uses traffic congestion information to inform its opportunistic use of non-minimal routes. An ingress port of a network switch collects traffic congestion information from the egress ports of the network switch. The traffic congestion information includes minimal and non-minimal route congestion metrics for the egress ports. Candidate egress ports for forwarding a packet to a destination node are identified. One of the candidate egress ports is selected based on the traffic congestion information. The selection process is biased to prefer some candidate egress ports over others. Particularly, the candidate egress ports that provide non-minimal routes to the destination node and have high minimal route congestion metrics are disfavored by the selection process.
