Technologies for quality of service based throttling in fabric architectures

A method for quality of service based throttling across a fabric architecture, the network node comprising:

• transmitting, by a host fabric interface (HFI) of a network node, an access request for access to a shared resource of one of a plurality of interconnected network nodes communicatively coupled to the network node via an interconnect fabric of the fabric architecture;
• receiving, by the HFI, a throttling message from the one of the plurality of interconnected network nodes;
• identifying, by the HFI, information associated with the received throttling message;
• and
• performing, by the HFI, a throttling action on one or more resources of the network node based on the identified information.

One or more non-transitory, machine-readable storage media comprising a plurality of instructions stored thereon that, when executed, cause a network node to:

• transmit, by a host fabric interface (HFI) of the network node, an access request for access to a shared resource of one of a plurality of interconnected network nodes communicatively coupled to the network node via an interconnect fabric of the fabric architecture;
• receive, by the HFI, a throttling message from the one of the plurality of interconnected network nodes;
• identify, by the HFI, information associated with the received throttling message;
• and
• perform, by the HFI, a throttling action on one or more resources of the network node based on the identified information.

A network node for quality of service based throttling in a fabric architecture in which the network node is one of a plurality of interconnected network nodes of the fabric architecture, the network node comprising:

• a communication management circuit to transmit an access request for access to a shared resource of one of the plurality of interconnected network nodes communicatively coupled to the network node via an interconnect fabric of the fabric architecture;
• a throttling message reception circuit to (i) receive a throttling message from a host fabric interface (HFI) of the one of the plurality of interconnected network nodes and (ii) identify information associated with the received throttling message;
• and
• a throttling response execution circuit to perform a throttling action on one or more resources of the network node based in the identified information.
