Tenant support is provided in a multi-tenant configuration in a data center by a Physical Function driver communicating a virtual User Priority to a virtual traffic class mapper to a Virtual Function driver. The Physical Function driver configures the Network Interface Controller to map virtual User Priorities to Physical User Priorities and to enforce the Virtual Function's limited access to Traffic Classes. Data Center Bridging features assigned to the physical network interface controller are hidden by virtualizing user priorities and traffic classes. A virtual Data Center Bridging configuration is enabled for a Virtual Function, to provide access to the user priorities and traffic classes that are not visible to the Virtual Function that the Virtual Function may need.

Method and apparatus for secure data center bridging in a multi-tenant system

Technologies for pacing network packet transmissions include a computing device. The computing device includes a compute engine and a network interface controller (NIC). The NIC is to select a first transmit descriptor from a window of transmit descriptors. The first transmit descriptor is associated with a packet stream. The NIC is also to identify a node of a plurality of nodes of a hierarchical scheduler. The node is associated with the selected first transmit descriptor. The NIC is also to determine whether the identified node has a target amount of transmission credits available and transmit, in response to a determination that the identified node has a target amount of transmission credits available, the network packet associated with the first transmit descriptor to a target computing device.
