1. A policy enforcer having load balancing capabilities, the policy enforcer comprises: multiple pairs of interfaces, each pair of interfaces comprises an input interface and a corresponding output interface; multiple data blades; a switch; and at least one load balancing circuit; wherein each pair of interfaces is located along a path between a radio access network (RAN) and an external network through which information packets should have propagated at an absence of the policy enforcer; wherein each input interface is arranged to receive a plurality of information packets that are associated with a plurality of user devices; wherein the at least one load balancing circuit is arranged to select, for each information packet, a selected policy enforcing processor out of multiple policy enforcing processors that belong to the multiple data blades; wherein the at least one load balancing circuit is arranged to select in response to an allocation of policy enforcing processors to user devices and to a user device associated with each information packet; wherein the at least one load balancing circuit is arranged to send each information packet over the switch to the selected policy enforcing processor associated with the information packet; wherein each selected policy enforcing processor is arranged to perform a policy enforcing operation on each information packet associated with the selected policy enforcing processor, to provide a policy enforced information packet; wherein the switch is arranged to direct each policy enforced information packet to an output interface of the policy enforcer that belongs to a pair of interfaces that comprises the output interface and an input interface from which an information packet was received before being converted to the policy enforced information packet; and wherein each output interface is arranged to output each policy enforced information packet received by the output interface.
