There are currently several applications and frameworks to simulate networks, network equipment, applications, services and protocols. These tools play an important role not only in the research and development of new solutions on the computer networking area, but also on other areas of knowledge, because they enable researchers to abstract from the underlying network complexity by providing a prepackaged set of simulation primitives in a concise and useful manner. These tools implement several models and network protocols, some of them being able to produce realistic network traffic, apart from simulating the behavior of the protocols or applications. It is well known that real network traffic in aggregation points like routers should exhibit the self-similarity property for the amount of information per time unit, which reflects the burstiness of the traffic and affects the functioning of the devices and protocols. It is …
