Abstract

   This document develops an architecture and a set of requirements
   needed to support alerting of hosts that are in dormant mode.  The
   architecture and requirements are designed to guide development of an
   IP protocol for alerting dormant IP mobile hosts, commonly called
   paging.

1.   Introduction

   In [1], a problem statement was developed to explain why an IP
   protocol was desirable for alerting hosts in dormant mode, commonly
   called paging.  In this document, a set of requirements is developed
