Nvidia patents method to pause data lanes for maintenance

Patent drawing from the official filing.

Nvidia describes a way to temporarily move data traffic from some communication lanes to others. This allows the device to perform tasks on the empty lanes before restoring normal traffic flow.

Why it mattersThis improves the reliability of high-speed data connections by allowing maintenance without dropping the entire link.

In the filing’s own words

A device connected to a link of a multi-lane communication interface causes link traffic to be migrated from multiple lanes of the multi-lane communication interface to a subset of the multiple lanes of the multi-lane communication interface. One or more tasks are performed on another subset of the plurality of lanes. Link traffic is caused to be restored on the multiple lanes.

What exactly they claim (claim 1)

1. A method comprising: causing, by a device connected to a link of a multi-lane communication interface, link traffic to be migrated from a plurality of lanes of the multi-lane communication interface to a first subset of the plurality of lanes of the multi-lane communication interface; performing one or more tasks on a second subset of the plurality of lanes; and causing the link traffic to be restored on the plurality of lanes.
