Abstract
In order to provide flexible scaling and dynamic reconfiguration, a wireless local area network controller includes a virtual dataplane with one or more virtual machines. These virtual machines pre-calculate processing parameters for packets in a data flow. For example, the pre-calculated processing parameters may include: encapsulation parameters, quality-of-service parameters and priority parameters. Subsequently, when one of the virtual machines receives a packet in the data flow on an input port, the virtual machine modifies information in a header of the packet based on one or more of the pre-calculated processing parameters and information associated with the data flow (which specifies the one or more pre-calculated processing parameters). Then, the virtual machine transmits the packet on an output port. In this way, the virtual machine maintains a fixed inter-packet time between packets in the data flow.
