Contemporary network services don't have any statistical ranking mechanism for proactive security management. Since the emerging threats are actively exploiting the vulnerabilities in network services to compromise the system, not much attention has been paid to rank these services based on their vulnerability history. We argue in this paper that a reliable mechanism could be used to rank these services...
We propose a new model for call arrival process on VoIP tandem networks under heavy traffic load condition. Based on empirical evidence, such call arrivals can be modeled as linear Gaussian processes, and we show that this approach can provide an intuitive and accurate representation for different traffic patterns. In addition, the Gaussian approximation allows finding explicit mathematical equations...
This paper presents a new approach to modeling call holding time of VoIP traffic on tandem networks. Call holding time is a key variable of traffic engineering models, and the traditional Erlang-B model uses the negative exponential function to model call holding time. Our study of hundreds of millions of telephone calls shows that the exponential assumption is not valid for modern large-scale VoIP...
