WebThe number of hops between Si and Mj, deduced from the TTL ﬁeld, is denoted by hij. A complete system with n such end hosts and m passive monitors results in an n£m hop-count matrix denoted by H. In practice, not all end hosts will be observed at every monitor, and therefore H is typically incomplete (i.e., hi;j is missing for certain i;j).
