Nvidia patents switch rules for adjusting data speeds between devices

Patent drawing from the official filing.

Nvidia describes a system where a network switch automatically changes the data speed of its connections to other devices. The switch listens for performance updates from those devices and uses a set policy to decide when to increase or decrease the bandwidth on a specific link.

Why it mattersThis filing outlines a method for managing data flow in high-speed computer networks, which could help servers and data centers use their connections more efficiently.

In the filing’s own words

A switch connected to multiple devices via multiple respective links initiates a change to a bandwidth of a respective link between the switch and at least one device of the multiple devices. Initiating the change to the bandwidth of the respective link includes sending a bandwidth change request to the at least one device.

What exactly they claim (claim 1)

1. A system comprising: a switch connected to a plurality of devices via a plurality of respective links of a communication interface, wherein the switch is to perform operations comprising: receiving, from a first device of the plurality of devices, a performance message conforming to a protocol of the communication interface; and determining, based on the received performance message and a link bandwidth policy, that a first bandwidth of a first link between the switch and the first device of the plurality of devices is to be updated to a second bandwidth.
