Abstract
According to one general aspect, a method of using a network device may include receiving, via an ingress port, a data packet that includes a payload portion, a source network address and a destination network address. In various embodiments, the method may also include determining if the data packet includes a security tag that includes a role based authentication tag. In some embodiments, the method may include, if the data packet includes a security tag that includes a role based authentication tag, transmitting, via an egress port, at least the payload portion and the role based authentication tag towards, in a topological sense, the destination network address.
