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.

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.
