   In order for routing of Diameter messages to work in a hierarchical 
   administrative domain, it is necessary to make use of sub-domains
   (see Figure 5). Routing with hierarchical domains requires the use of
   longest match from right.
   
                             +---------+
                             | abc.com |
                             +---------+
   
                +-------+                 +-------+
                | agent |                 | agent |
                +-------+                 +-------+
   
     +-------------+ +--------------+ +-------------+ +--------------+ 
     | eng.abc.com | | acct.abc.com | | mkt.abc.com | | exec.abc.com |
     +-------------+ +--------------+ +-------------+ +--------------+
