1.  Introduction

   Light weight machine to machine (LWM2M) protocol is used to manage
   end device life cycle in machine to machine communication scenarios.
   LWM2M device bootstrap is an optional life cycle phase for devices to
   get needed information when starting up for first time.  Information
   gathered during bootstrapping might include management server details
   and security certificates required to establish connectivity with
   management server.  Information required to connect with bootstrap
   server might be hard coded during device manufacturing phase.

   Hard coding configuration by device manufacturer forces device
   operator to use same configuration as hard coded.  It is possible
   that reachability information of bootstrap server that is hard coded
   may be outdated and boot strap server reachability might fail during
   first use of device.  In such cases connectivity with bootstrap
   server is possible only through device software upgrade.

2.  Terminology

   LWM2M:  Lightweight Machine to Machine is a protocol from Open Mobile
