提供了IEEE通信杂志，第12卷，第1号（1994年1月）的特别问题的概述，解决了网络的完整性，可靠性和生存性的开放性问题。讨论了这一领域目前的进展情况。所解决的问题包括用户的生存能力的标准，规划和部署的角度来看，网络灾难的分析和量化，生存和容错的网络架构和相关的经济分析，以及技术来处理网络恢复的物理损坏或软件和控制系统故障的结果。特别关注的是宽带网络的生存性，采用新的传输/交换技术的基础上，同步光网络（SONET）和异步传输模式（ATM）标准，由于它们在未来的B-ISDN的新兴作用。由于公共信道信令（CCS）系统的故障而导致的网络完整性也是非常关键的。目前的特刊包括22篇论文，并分为以下几个部分：用户的观点和规划，软件质量和可靠性，网络生存能力的表征和标准，SONET网络的网络恢复，ATM网络的网络恢复，计算机网络的流量影响和性能增强，以及生存网络设计方法。SONET、ATM和计算机网络的网络恢复方法对应于CCITT宽带ISDN层结构中定义的物理层（SONET）、ATM层和网络层的方法。>
Provides an overview of the special issue of the IEEE Journal of Communications, Volume 12, Number 1 (January 1994) which addresses open questions in network integrity, reliability and survivability. Current progress in this area is discussed. The questions addressed include user survivability perspectives on standards, planning, and deployment; the analysis and quantification of network disasters; survivable and fault-tolerant network architectures and associated economic analyses; and techniques to handle network restoration as a result of physical damage or failures in software and control systems. Special interests are devoted to the survivability of broadband networks employing the new transport/switching techniques based on the synchronous optical network (SONET) and asynchronous transfer mode (ATM) standards due to their emerging role in future B-ISDN. Network integrity due to failures of common channel signaling (CCS) systems is also very critical. The present special issue includes 22 papers and is organized into the following sections: user perspectives and planning, software quality and reliability, network survivability characterization and standards, network restoration for SONET networks, network restoration for ATM networks, traffic effect and performance enhancement for computer networks, and survivable network design methods. Network restoration methods for SONET, ATM, and computer networks correspond to those for the physical layer (SONET), ATM layer, and the network layer, defined in the CCITT broadband ISDN layer structure. >
