In this paper, we propose a stateful optical filtering approach that allows session establishment and traffic flow filtering in the optical layer. Each traffic flow is identified by a unique identifier composed of a set of code words built on values of appropriately selected fields in the stream. In the firewall core node, a security policy is applied to the optical flow based on its identifier in...
In this paper, we propose an optical stateless filtering architecture which allows the traffic filtering at the optical layer. Indeed, each traffic stream will be identified by a unique identifier composed of a set of code words. In the core node, a set of optical filtering rules will be applied to this traffic stream based on its corresponding identifier in order to accept or reject the traffic stream...
