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 switch fabrics
The present disclosure relates to multi-path routing of a switch fabric. The switch fabric uses traffic congestion information to inform its timely use of non-minimal routes. An ingress port of a network switch collects traffic congestion information from 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 are identified for forwarding a packet to a destination node. One of the candidate egress ports is selected in accordance with the traffic congestion information. The selection process favors selecting some candidate egress ports over others. In particular, non-minimal routes to the destination node and candidate egress ports having high minimal route congestion metrics are disfavored by the selection process.

ActiveUS12483813B2Multiplex system selection arrangementsWavelength-division multiplex systemsTransceiverEngineering
This disclosure describes multiplexed optical transceivers, such as DWDM multiplexer / demultiplexers, which are aggregated in a server chassis to establish a fabric topology interconnecting blade servers to a dedicated switch module. Blade servers installed in the server chassis can utilize not just Ethernet interfaces to connect to network segments, but also PCIe interfaces as well as a combination of Ethernet and PCIe interfaces. The aggregated optical transceivers multiplex and demultiplex wavelength-specific optical signals using a laser source, reducing power consumption over switched fabric ASICs. Servicing of the multiplexed optical transceivers is facilitated by installation and replacement of a laser source. Scaling and redundancy of fabric topology interconnects can be facilitated by selection of laser sources generating expanded ranges of discrete wavelengths. Furthermore, chassis management can be facilitated by configuring network controllers of blade servers to transport chassis management instructions over the fabric topology in-band over a network interface, rather than by an out-of-band pathway.

Fabric control protocol for data center networks with packet spraying over multiple alternate data paths
A fabric control protocol is described for use within a data center in which a switch fabric provides full mesh interconnectivity such that any of the servers may communicate packet data for a given packet flow to any other of the servers using any of a number of parallel data paths within the data center switch fabric. The fabric control protocol enables spraying of individual packets for a given packet flow across some or all of the multiple parallel data paths in the data center switch fabric and, optionally, reordering of the packets for delivery to the destination. The fabric control protocol may provide end-to-end bandwidth scaling and flow fairness within a single tunnel based on endpoint-controlled requests and grants for flows. In some examples, the fabric control protocol packet structure is carried over an underlying protocol, such as the User Datagram Protocol (UDP).

Continuity Synchronization Protocol Rail for Maintaining Session Continuity Across Heterogeneous User-Interface Nodes
A continuity synchronization protocol rail system maintains persistent session continuity across heterogeneous user-interface nodes using a continuity anchor device that derives non-invertible continuity tokens from biometric or interaction-derived signals combined with a device-specific secret. Communication interfaces exchange structured continuity synchronization messages comprising continuity token references and cryptographically authenticated reconciliation requests between the anchor device and user-interface nodes. Processors apply reconciliation rules comprising timestamp-based ordering, session freshness weighting, or deterministic merge operations to resolve partial or concurrent session contexts. Session context is restored upon re-detection of a continuity token satisfying a predefined continuity confidence threshold following an interruption event, without requiring cloud authentication, persistent user accounts, or centralized identity directories. Continuity restoration is authorized only under control of the continuity anchor device. The system supports offline operation and policy-adaptive compliance modes.
