摘要: In this paper, we describe an experimental study of Internet topological stability and the origins failure in protocol backbones. The end-to-end paths is dependent both on underlying telecommunication switching system, as well higher level software hardware components specific to Internet's packet-switched forwarding routing architecture. Although a number earlier studies have examined failures public little attention has been given characterization stability. We provide analysis major between Service Providers based instrumentation key portions infrastructure. unexpectedly high levels path fluctuation aggregate low mean time for individual paths. also case network observed large regional backbone. characterize type, origin, frequency duration these failures.
