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).

Time to live (TTL) or hop limit is a mechanism which limits the lifespan or lifetime of data in a computer or network. TTL may be implemented as a counter or timestamp attached to or embedded in the data. Once the prescribed event count or timespan has elapsed, data is discarded or revalidated.
