摘要：
应急服务通信系统（ESCS）正在向基于互联网协议（IP）的通信网络演进，有望提升其功能、可用性和韧性。这种复杂性和网络攻击面的增加，要求我们更好地理解这些系统在极端情况下的故障动态。现有ESCS研究在很大程度上忽视了仿真，而少量已有工作主要聚焦于网络安全威胁，忽略了呼叫到达的非平稳性等关键因素。本文提出了一个稳健、可适配的基于图的仿真框架，以及用于ESCS仿真的基础数学模型。该框架采用一种ESCS表示方法，其中每个顶点是一个通信有限状态机，沿边交换消息，其行为由离散事件排队模型控制。呼叫到达突发性及其与紧急事件之间的关联通过簇点过程进行建模。通过对西雅图警察局ESCS的仿真，证明了模型的适用性。正在进行的工作包括开发GPU实现，并探索其在网络安全桌面推演中的应用。
英文摘要：
Emergency Services Communication Systems (ESCS) are evolving into Internet Protocol based communication networks, promising enhancements to their function, availability, and resilience. This increase in complexity and cyber-attack surface demands better understanding of these systems' breakdown dynamics under extreme circumstances. Existing ESCS research largely overlooks simulation and the little work that exists focuses primarily on cybersecurity threats and neglects critical factors such as non-stationarity of call arrivals. This paper introduces a robust, adaptable graph-based simulation framework and essential mathematical models for ESCS simulation. The framework uses a representation of ESCSes where each vertex is a communicating finite-state machine that exchanges messages along edges and whose behavior is governed by a discrete event queuing model. Call arrival burstiness and its connection to emergency incidents is modeled through a cluster point process. Model applicability is demonstrated through simulations of the Seattle Police Department ESCS. Ongoing work is developing GPU implementation and exploring use in cybersecurity tabletop exercises.
