Since faults unavoidably occur in communication networks, it is important to quickly and
accurately localize the faults to ensure the stability, consistency and reliability of …

Effective use of monitoring tools demands an understanding of monitoring requirements
which system administrators most often lack. In this paper, we propose to replace today's ad …

Fault detection in modern networks is done with a set of specially instrumented nodes which
send probes to find faults. These probes generate additional traffic in network and compete …

Fault detection and localization is a central element in the management of network failures. It
allows inferring the exact failure of a network from all the observed symptoms. Because …

Probing is a commonly used technique to identify faults in computer networks. Contrary to
the static probes which are otherwise common, we consider the problem of selecting probes …

Fault diagnosis is a central aspect of network fault management. Since faults are
unavoidable in communication systems, their quick detection and isolation is essential for …

In this paper, we propose a new approach to the performance supervision of complex and
heterogeneous infrastructures found in hybrid cloud networks, which typically consist of …

Fault detection for wireless sensor networks (WSNs) has been studied intensively in recent
years. Most existing works statically choose the manager nodes as probe stations and probe …

摘要通信网络中数据传输能力强的节点实时负载高, 传输价值高, 在进行故障探测时会产生较高
