In the computer science field coordinated vulnerability disclosure is a well-known practice for finding flaws in IT-systems and patching them. In this practice, a white-hat hacker who finds a vulnerability in an IT-system reports that vulnerability to the system’s owner. The owner will then resolve the problem, after which the vulnerability will be disclosed publicly. This practice generally does...
This paper discusses some modeling issues concerning the communication between goal-directed agents. In particular, the role of performatives in agent communication is discussed. It is argued that the specification of the effect of performatives, as prescribed by FIPA, is sometimes too weak or unrealistic. The alternative, proposed in this paper, suggests a two phase modeling of the effect of the...
Optical or lambda exchanges have emerged to interconnect networks, providing dynamic switching capabilities on OSI layer 1 and layer 2. So far, the only inter-domain dynamics have occurred on layer 3, the IP layer. This new functionality in the data plane has consequences on the control plane. We explain this by comparing optical exchanges with current Internet exchanges. Descriptions of optical...
