Abstract
This document is an overview of a workshop held by the Internet
Architecture Board (IAB) on the Internet Network Layer architecture
hosted by SURFnet in Utrecht, the Netherlands on 7-9 July 1999. The
goal of the workshop was to understand the state of the network layer
and its impact on continued growth and usage of the Internet.
Different technical scenarios for the (foreseeable) future and the
impact of external influences were studied. This report lists the
conclusions and recommendations to the Internet Engineering Task
Force (IETF) community.

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.
