1.  Introduction

   In [1], the concept of a "content network" is introduced and
   described.  In addition to describing some general types of content
   networks, it also describes motivations for allowing content networks
   to interconnect (defined as "content internetworking").

   In describing content internetworking as a technology targeted for
   use in production networks, it's useful to provide examples of the
   sequence of events that may occur when two content networks decide to
   interconnect.  Naturally, different types of content networks may be
   created due to different business motivations, and so many
   combinations are likely.

   This document first provides detailed examples of special cases of
   content networks that are specifically designed to participate in
   content internetworking (Section 2).  We then discuss the steps that
   would be taken in order to "bring up" or "tear down" a content
   internetworking arrangement (Section 3).  Next we provide some
   detailed examples of how content networks (such as those from Section
   2) could interconnect (Section 4).  Finally, we describe any security
   considerations that arise specifically from the examples presented
   here (Section 5).

   The scenarios presented here answer two distinct needs:

   1. To provide some concrete examples of what content internetworking
      is, and

   2. To provide a basis for evaluating content internetworking
      proposals.

   A number of content internetworking systems have been implemented,
   but there are few published descriptions. One such description is
   [2].

1.1.  Terminology

   Terms in ALL CAPS are defined in [1] except for the following terms
   defined below in this document: PCN, BCN, and LCN.  Additionally, the
   term SLA is used as an abbreviation for Service Level Agreement.
