<abstract>
<t>The original Internet architecture assumed that each network is labeled with a single IP network number.  This assumption may be violated for shared media, including "large public data networks" (LPDNs).  The architecture still works if this assumption is violated, but it does not have a means to prevent multiple host- router and router-router hops through the shared medium.  This memo discusses alternative approaches to extending the Internet architecture to eliminate some or all unnecessary hops.</t></abstract></front>
