The key to a successful hierarchical network structure is proper IP address management. If addresses are assigned appropriately, it is possible to summarize routing information. TIP Each area used by OSPF or integrated IS-IS should have a contiguous set of network or subnet numbers assigned to it. The area border routers should summarize that set of addresses with an address mask. Summarization provides substantial benefits for your network.

INSTRUMENTATION SYSTEM INTEGRATION AND INTERFACES Technical evolution and economic influences have combined to define the integration of contemporary multisensor instrumentation systems relative to a delineation of applications. A hierarchical instrumentation taxonomy is accordingly described as illustrated by discrete automatic test equipment, remote measurement environments, automation system virtual instruments, and analytical instrumentation for aiding sensed-feature understanding.

Like most operating systems in the last 40 years, Unix uses a hierarchical "tree-structured" file system (interestingly, tree-structure and other aspects of the Unix file system are a direct result of the original Unix developers being influenced by the Multics project they had been working on). Directories contain files and subdirectories which, may in turn, contain other files and subdirectories, and so on.
