揭示核心传输网络中的潜在故障传播场景
Unveiling Potential Failure Propagation Scenarios in Core Transport Networks
摘要：
现代社会越来越依赖电信网络。由这种网络支持的新服务和技术，如云计算或电子健康，在现代生活中发挥着至关重要的作用。大规模的故障很容易发生，从而对商业组织和个人构成持续的威胁。据我们所知，目前还没有关于核心传输网络中故障传播的公开报道。此外，软件定义网络（SDN）在我们的社会中变得越来越普遍，并且我们可以设想未来更多的SDN控制的骨干传输网络（BTNs）。出于这个原因，我们调查的主要动机，可能会导致类似的失败BTNs和SDNTNs。为此，我们招募了几个在流行病、网络弹性和安全方面具有重要背景的研究小组的专业知识。此外，我们考虑了三个网络提供商的经验。我们的研究结果表明，动态传输网络（DTNs）是容易出现类似于蠕虫的故障。此外，我们提出了不同的情况下，故障可以传播SDNTNs。我们相信，关键的发现将有助于网络工程师和科学界预测这种灾难性的故障场景，并计划适当的生存策略。
英文摘要：
The contemporary society has become more dependent on telecommunication networks. Novel services and technologies supported by such networks, such as cloud computing or e-Health, hold a vital role in modern day living. Large-scale failures are prone to occur, thus being a constant threat to business organizations and individuals. To the best of our knowledge, there are no publicly available reports regarding failure propagation in core transport networks. Furthermore, Software Defined Networking (SDN) is becoming more prevalent in our society and we can envision more SDN-controlled Backbone Transport Networks (BTNs) in the future. For this reason, we investigate the main motivations that could lead to epidemic-like failures in BTNs and SDNTNs. To do so, we enlist the expertise of several research groups with significant background in epidemics, network resiliency, and security. In addition, we consider the experiences of three network providers. Our results illustrate that Dynamic Transport Networks (DTNs) are prone to epidemic-like failures. Moreover, we propose different situations in which a failure can propagate in SDNTNs. We believe that the key findings will aid network engineers and the scientific community to predict this type of disastrous failure scenario and plan adequate survivability strategies.
