Abstract: Embodiments of network processing resource management in computing devices are disclosed therein. In one embodiment, a method includes receiving a request from a network interface controller to perform network processing operations at a first core of a main processor for packets assigned by the network interface controller to a queue of a virtual port of the network interface controller. The method also includes determining whether the first core has a utilization level higher than a threshold when performing the network processing operations to effect processing and transmission of the packets. If the first core has a utilization level higher than the threshold, the method includes issuing a command to the network interface to modify affinitization of the queue from the first core to a second core having a utilization level lower than the threshold.

Abstract: Embodiments of network traffic management in a computing device are disclosed therein. In one embodiment, a method includes receiving, at a main processor, a request from a network interface controller to perform network processing operations for packets assigned by the network interface controller to a queue of a virtual port of the network interface controller. The method also includes, in response to receiving the request, causing one of multiple cores of the main processor with which the queue of the virtual port is affinitized to perform the network processing operations to effect processing and transmission of the packets to an application executing in a virtual machine hosted on the computing device.

Abstract: The disclosed system implements techniques to enable a tenant of a cloud-based platform to effectively and efficiently apply a policy that copies data packets communicated to or from a virtual machine in the tenant's own virtual network. When applied, the policy mirrors data traffic associated with a workload executing on a virtual machine in the tenant's virtual network. To mirror the data traffic, a copy of a data packet is streamed to another virtual machine so that network analytics can be performed (e.g., performance analytics, security analytics, etc.). In various examples, the policy can be a role-based mirroring policy that defines a plurality of roles in association with a role-based access model that scales operations and that provides improved security for a tenant's virtual network.
