1. A method for use with a packet network that transports packets between distinct first, second, and third entities over a packet network under control of a controller that is external to a network node, the method comprising:
receiving, by the network node from the controller over the packet network, an instruction that comprises an identifier of the third entity and a criterion;
receiving, by the network node from the first entity over the packet network, a packet that is addressed to the second entity;
determining, by the network node, whether the received packet satisfies the criterion;
sending, by the network node to the second entity over the packet network, the packet, in response to the packet not satisfying the criterion; and
sending, by the network node to the third entity over the packet network, in response to the packet satisfying the criterion.
