在现代分组交换电信系统中，信息（例如电子邮件、声音、图片）以数据的小分组（或信元）的形式通过链路和路由器的网络传输。由这样的网络提供的服务质量可能遭受诸如分组丢失（由于缓冲区溢出）和过度延迟的现象。这些方面的系统充分描述了嵌入式模型，这样的模型的研究是非常相关的设计系统，使他们提供所需的QoS。本论文提出了在各种通信系统模型中有效估计几种损失概率的方法。重点是稀有事件模拟使用重要性抽样，但也提供了一些分析，渐近和数值结果。
In modern packet-switched telecommunication systems, information (such as email, sound, pictures) is transported in the form of small packets (or cells) of data through a network of links and routers. The Quality of Service provided by such a network can suffer from phenomena such as loss of packets (due to buffer overflow) and excessive delays. These aspects of the system are adequately described by queueing models, so the study of such models is of great relevance for designing systems such that they provide the required QoS. This thesis contributes methods for the efficient estimation of several loss probabilities in various queueing models of communications systems. The focus is on rare-event simulation using importance sampling, but some analytical, asymptotic and numerical results are also provided.
