1. An apparatus, comprising:
a port configured to exchange signals with a router; and
at least one processor configured to:
implement a virtual machine having state information associated therewith;
receive packets from the router via the port, perform operations on the packets using the virtual machine, and send the packets back toward the router via the port; and
implement a user plane layer that determines a processing load on the virtual machine based on monitoring of at least one of the virtual machine or the state information, generates feedback representative of the processing load on the virtual machine, and provides the feedback to the router via the port.
