TRAFFIC AND LOAD AWARE DYNAMIC QUEUE MANAGEMENT

摘要

Some embodiments provide a queue management system that efficiently and dynamically manages multiple queues that process traffic to and from multiple virtual machines (VMs) executing on a host. This system manages the queues by (1) breaking up the queues into different priority pools with the higher priority pools reserved for particular types of traffic or VM (e.g., traffic for VMs that need low latency), (2) dynamically adjusting the number of queues in each pool (i.e., dynamically adjusting the size of the pools), (3) dynamically reassigning a VM to a new queue based on one or more optimization criteria (e.g., criteria relating to the underutilization or overutilization of the queue).

1. For an electronic device that comprises a network interface card (NIC) with a plurality of queues for temporarily storing data traffic through the NIC, a method of managing the queues, the method comprising:
assigning a subset of data traffic to a first queue; monitoring the subset of data traffic through the first queue; and based on the monitoring, re-assigning the subset of data traffic to a second queue.
