Dynamic vulnerability assessments of software-defined networks

The networks (SDN) poses many potential security threats because of its principle of dissociating the network management interface from the underneath networking components and making a programmable networking system. Many security countermeasures have been proposed regarding this current trending environment, but none of the research has considered the existing vulnerabilities in SDN entities. This paper demonstrates the vulnerabilities using CVSS in the first place and then identifies the mutual relationship between the vulnerabilities using Bayesian network methodology.

电力通信网设备网管自动化测试平台研究

本文提出了一种电力通信网设备网管自动化测试平台，该平台涉及多接口技术适配领域。多接口技术适配模块主要负责依据给定的参数封装网管接口消息报文并发送给被测NMS系统或被测EMS系统，以及接收并解析被测系统响应消息。本文所提测试平台能够根据测试任务的具体内容将测试任务分配给不同的测试仪，提高了测试的有效性，同时测试仪具有在线和离线两种工作模式，使得测试更加方便灵活。 This paper presents an automatic test platform for network management of electric power com-munication network, which involves the field of the multi-interface technology. Multi-interface technology adapter module is mainly responsible for the information of the network management interface message packet and sent to the tested NMS system or measured EMS system, as well as receiving and analyzing the response message of the system. The test platform can distribute test tasks to different testers according to the specific content and improve the effectiveness of testing. And, test instrument with online and offline work makes the test more convenient and flexible.

Optical layer signaling: how much is really needed?

This article challenges the emerging industry trend of adapting Internet-style distributed network-control with its full complexity for the optical transport network. Instead, we argue that an extensive telecom-style network management interface augmented with a minimal control plane and a service layer interface between management systems is more appropriate for the real needs of the optical layer. This approach will allow more flexibility in extending the interoperability between vendors and carriers as our understanding of these networks grows, increase the reliability of the network, and be a better fit for the telecom service provider. On the other hand, the simplicity of use and automation the Internet control plane promises can just as easily be achieved with our proposal.
