Several tools exist that collect host-to-host connectivity measurements. To improve the usability of such measurements, they should be mapped into a framework consisting of complex subsystems, and the infrastructure that connects them. We introduce one such framework, and analyze the architectural implications on the network structure. In our framework, a complex subsystem consists of several computing facilities and the infrastructure that connects them: we call it a -monitoring domain-. The task of measuring the connectivity between -monitoring domains- is considered distinct from the activity of -storage- and -computing- elements. Therefore we introduce a new element in our topology: we call it -theodolite- element, since its function is similar to that of a transponder. Using these basic concepts, we analyze the architectural implications on the network structure: in a nutshell, if we want that -theodolites- serve as a reference, than the contribution to the relevant network metrics due to the -monitoring domain- infrastructure must be negligible with respect to contributions of the inter-domain infrastructure. In addition all -theodolites- of a -monitoring domain- must give an image of the inter-domain infrastructure that is consistent with that experienced by network applications. We conclude giving a running SQL example of how information about -monitoring domains- and -theodolites- could be organized, and we outline the application of such framework in the GLUE schema activity for the network element
Monitoring the energy consumed by a network infrastructure to detect and isolate faults in communication architecture
近年来，在计算机网络、高能效网络协议和网络管理系统领域中引入了一些重大改进。软件定义网络（Software Defined Network，SDN）作为管理复杂网络的新范式，为降低ICT能耗带来了重要机遇。在本文中，我们正在解决监控网络设备状态和优化现有解决方案的过程中的改进。我们正在监控网络架构的能耗，并增加检索到的原始功率数据，以检测设备状态的变化。目标是对从实际测量中获取的功率数据与从功率模型中提取的数据之间的差异进行基准测试，转换为设备的预期行为。该应用程序旨在监控和分析由思科交换机和路由器、Dell Precision工作站和Raritan PDU组成的模拟ICT基础架构的检索到的电源数据。此外，开发了智能算法，其结果是检测设备状态的变化，以及检测和隔离可能的异常及其对能耗的影响。该应用被设想为现有SDN控制器的扩展，用于监控和报告ICT设备状态的变化。
