US 2020/0028792 A1 · DYNAMIC PROCESSING OF PACKETS USING MULTIPLE RECEIVE QUEUE FEATURES

Abstract

Some embodiments provide a method for managing multiple queues of a network interface card (NIC) of a host computer that executes a data compute node (DCN). The method defines first, second, and third subsets of the queues. The first subset of queues is associated with a first feature for processing data messages received by the NIC, the second subset of queues is associated with a second feature, and the third subset is associated with both features. The method receives a request from the DCN to process data messages addressed to the DCN using both the first and second features. The method configures the NIC to direct data messages received for the DCN to a queue that is selected from the third subset of queues.

Dependent claims

A method for managing a plurality of queues of a network interface card (NIC) of a host computer, the method comprising:

defining first, second, and third subsets of the queues, wherein the first subset of queues is associated with a first feature for aggregating multiple related data messages received by the NIC into a single data message, the second subset of queues is associated with a second feature for load balancing data messages received by the NIC across multiple queues, and the third subset of queues is associated with both the first and second features;
receiving a request from a data compute node (DCN) executing on the host computer for data messages addressed to the DCN to be processed with both the first feature for aggregating multiple related data messages into a single data message and second feature for load balancing data messages across multiple queues;
and
configuring the NIC to direct data messages received for the DCN to a particular queue selected from the third subset of queues.

A non-transitory machine readable medium storing a program which when executed on set of processing units of a host computer manages a plurality of queues of a network interface card (NIC) of the host computer, the program comprising sets of instructions for:

defining first, second, and third subsets of the queues, wherein the first subset of queues is associated with a first feature for aggregating multiple related data messages received by the NIC into a single data message, the second subset of queues is associated with a second feature for load balancing data messages received by the NIC across multiple queues, and the third subset of queues is associated with both the first and second features;
receiving a request from a data compute node (DCN) executing on the host computer for data messages addressed to the DCN to be processed with both the first feature for aggregating multiple related data messages into a single data message and second feature for load balancing data messages across multiple queues;
and
configuring the NIC to direct data messages received for the DCN to a particular queue selected from the third subset of queues.
