Modeling of next-generation firewalls as queueing services
Sergey Vladimirovich Zapechnikov, Natalia Georgievna Miloslavskaya, Alexander I. Tolstoy · 2015
The paper presents an analytical model to study the performance and availability of queueing systems with finite queue and a lot of service phases. The first phase has the exponential distribution of service time, while the second one has the hyper-Erlangian distribution. The analytical results obtained are verified using discrete-event simulation. A few numerical examples for varying the service rates and arrival rates are given. The results presented in the paper can be used for analysis of the Next Generation Firewalls (NGFWs).
