1. Introduction

   From July 7 to July 9, 1999 the Internet Architecture Board (IAB)
   held a workshop on the architecture of the Internet Network Layer.
   The Network Layer is usually referred to as the IP layer.  The goal
   of the workshop was to discuss the current state of the Network Layer
   and the impact various currently deployed or future mechanisms and
   technologies might have on the continued growth and usage of the
   Internet.

   The most important issues to be discussed were:

   o  Status of IPv6 deployment and transition issues
   o  Alternative technical strategies in case IPv6 is not adopted
   o  Globally unique addresses and 32 bit address depletion
   o  Global connectivity and reachability
   o  Fragmentation of the Internet
   o  End to end transparency and the progressive loss thereof
   o  End to end security
   o  Complications of address sharing mechanisms (NAT, RSIP)
   o  Separation of identification and location in addressing
   o  Architecture and scaling of the current routing system

   The participants looked into several technical scenarios and
   discussed the feasibility and probability of the deployment of each
   scenario.  Among the scenarios were for example full migration to
   IPv6, IPv6 deployment only in certain segments of the network, no
   significant deployment of IPv6 and increased segmentation of the IPv4
   address space due to the use of NAT devices.

   Based on the discussion of these scenarios several trends and
   external influences were identified which could have a large impact
   on the status of the network layer, such as the deployment of
   wireless network technologies, mobile networked devices and special
   purpose IP devices.
