Abstract
Selectively enabling communication of dual protocol packets from a source device directed to a service of an object class at target devices is provided. Steps can include providing an access control database including an entry correlating a source device, an object class and a service of the object class; from a source device, receiving a dual protocol packet including a frame and a field according to a first network communication protocol and an encapsulated packet of a second network communication protocol; obtaining from the frame, an identification of the source device; obtaining from the encapsulated packet, an identification and a service of an object class to which the encapsulated packet is directed; comparing the identification of the source device, the identification and service of the object class, and the entry of the access control database; and selectively transmitting the dual protocol packet as a function of the comparison.
