    • A simulation method and system partitions network traffic into background traffic and explicit traffic, wherein explicit traffic is processed in detail, and background traffic is processed at a more abstract level. The packets of explicit traffic are modeled in complete detail, so that precise timing and behavior characteristics can be determined, whereas large volumes of traffic are modeled more abstractly as background flows, and only certain aspects, such as routing through the network, are simulated. Tracer packets are used to model the background traffic and carry a number of characteristics of interest for generating simulation results. In this manner, the effect of the background traffic on the explicit traffic can be modeled at each network element. The abstract processing of background traffic is facilitated by techniques that include multi-variate table look-up, neural networks, and the like.
    • 模拟方法和系统将网络流量分为后台流量和显式流量,其中详细处理显式流量,并且以更抽象的级别处理后台流量。 明确流量的数据包将被完整的建模,从而可以确定精确的时序和行为特征,而大量的流量则作为背景流更抽象地进行建模,只有模拟网络路由等某些方面。 示踪器数据包用于对后台流量进行建模,并携带多个感兴趣的特性以生成仿真结果。 以这种方式,可以在每个网络元件上对后台流量对显式流量的影响进行建模。 通过包括多变量表查找,神经网络等的技术来促进背景流量的抽象处理。
