Introduction

The Interworking Seminar in Autumn 2002 is titled Internet Protocols for Mobile Computing. The title reflects the current transition to all IP-networks in the third generation of mobile commmunications. Its most straightforward implication is that IP is the common nominator as the networking, that is OSI layer 3, protocol. However, IP is not the only Internet technology that the future mobile communication systems will exploit.

The IETF---Internet Engineering Task Force---is a huge standardization forum. In November 2002 IETF has 136 active working groups divided into eight work areas: Applications Area, General Area, Internet Area, Operations and Management Area, Routing Area, Security Area, Sub-IP Area, and Transport Area. Therefore, a seminar can only take a climpse at on-going activities in the IETF. However, the papers in our proceedings give quite comprehensive overview of current IETF activities related to Internet protocols for mobile computing.

For mobile computing, the Internet infrastructure can be divided into groups like:

IP middleware:
protocols that provide generic services above transport including protocols for sessions, location, messaging, service discovery.
IP management and control:
protocols that are used to manage and control network and services.
IP transport:
protocols that provide end-to-end delivery of data such as TCP, UDP, SCTP, RTP, DCCP.
IP mechanisms:
protocols that provide Quality-of-Service, security, and mobility.
IP networking
IPv6 and protocols for autoconfiguration, multicast, address translations, etc.
IP adaption:
generic interfaces for IP mechanisms to take advantage of link layer capabilities.
It should be noted that the classification above does not include application protocols. In addition, one of the key enablers of the forthcoming Wireless Internet, that is XML and its derivations, does not belong to the "IETF family", but handled by W3C or World Wide Web Consortium.
