本文提出了一种创新的模拟技术，用于评估存在弹性流量时路由算法的性能。用于评估路由策略的传统模拟工具基于呼叫的生成，呼叫的长度在连接进入网络时确定。但互联网连接的实际持续时间取决于要传输的信息量和网络的（随时间变化的）拥塞程度。这里提出的性能方法考虑了互联网流量的性质，同时保持基于呼叫的事件驱动模拟的效率。结果表明，基于传统方法的结论可能与本文提出的更准确的方法得出的结论相去甚远。
An innovative simulation technique for the performance of routing algorithms in presence of elastic traffic is proposed in this paper. Traditional simulation tools for the evaluation of routing strategies are based on the generation of calls whose length is determined when the connection enters the network. But the real duration of connections in the Internet depends on the amount of information to be transferred and the (time varying) congestion level of the network. The performance method proposed here takes into account the nature of Internet traffic, while maintaining the efficiency of call based event-driven simulations. Results show that conclusions based on traditional methods can be very far from those obtained with the more accurate method proposed here.
