Estimation of Critical Components of Internet Infrastructure

The article analyses the connectivity of Internet - one of the fundamental network characteristics - on the basis of network topology analysis. The metrics compiled allows identifying the critical elements of Internet network infrastructure: critical and ɳ -critical nodes and critical as well as critical and k -critical links. The model of monitoring the critical network elements was created, and the algorithm of realizing was described.
