Binary network tomography
WebNetwork tomography is a well developed eld [1, 4, 7]. However, the vast majority of performance tomography has concentrated on trees. In that setting, it is possible to de-velop fast, recursive algorithms [2, 4], and to employ side information such as sparsity relatively easily [3]. However, many networks are not trees. Some work has Webexisting binary networking tomography algorithms to iden-tify failures. We evaluate the ability of network tomography algorithms to correctly detect and identify failures in a con-trolled environment on the VINI testbed.

Network tomography seeks to map the path data takes through the Internet by examining information from “edge nodes,” the computers in which the data are originated and from which they are requested. The field is useful for engineers attempting to develop more efficient computer networks. See more Network tomography is the study of a network's internal characteristics using information derived from end point data. The word tomography is used to link the field, in concept, to other processes that infer the internal … See more Network tomography may be able to infer network topology using end-to-end probes. Topology discovery is a tradeoff between accuracy vs. … See more There have been many published papers and tools in the area of network tomography, which aim to monitor the health of various links in a network in real-time. These can be classified into loss and delay tomography. Loss tomography See more • Network science • Computer network See more WebBoolean network tomography is another well-studied branch of network tomography, which addresses the inference of binary performance indicators (e.g., normal vs. failed, or uncongested vs. congested) of internal network elements from the corresponding binary performance indicators on measurement paths.
