Nvidia patents network fix that lets computers spot failures faster

This filing describes a method where individual computers in a network detect when a connection drops, rather than waiting for the central switch to notice. When a failure is found, the system quickly shifts traffic to a backup path to keep data moving smoothly.

Why it mattersIt could make large data centers more stable by reacting to connection problems in milliseconds instead of seconds.

In the filing’s own words

Embodiments of the present disclosure are directed to the proactive re-routing of network traffic upon a failure of a link or node of the network in a manner that reduces overall performance degradation. As described herein, embodiments use a host or other node of the network to detect and react to the failure instead of a switch since the host or node can do so more quickly than the switch. Once the host or node detects a failure, that host or node can cause communications between the nodes to switch from one node, such as packet spray routing, for example, to another node, such as Equal Cost Multi-Path (ECMP) routing, for example. Packets intended for the failed node can be re-routed to other nodes and the communications can be returned to the original mode.

What exactly they claim (claim 1)

1. A processor comprising: one or more circuits to perform an instruction to cause one or more processors to: conduct, through a switch of the communication network, electronic communications between a plurality of nodes of a communication network in a first mode; detect, by a first node of the plurality of modes, a link failure to a second node of the plurality of nodes; and in response to detecting the link failure of the second node, cause, by the first node, the electronic communications between the plurality of nodes to be conducted in a second mode.
