“Network Coding & Network Tomography “by Prof.Sumit Roy

Network tomography seeks to infer internal link status parameters (such as delay)  through  end-to-end measurements at (external) boundary nodes. As can be expected, such approaches generically suffer from identifiability problems; i.e., inability to uniquely identify individual link status for many …
