IPv6 Status


On the 3rd December 2011, the winners had been decorated on the 4th German IPv6 Summit by the German IPv6 Council.

Winners of the category Applications & Implementations

1st place: WinSEND: Windows SEcure NEighbor Discovery

Ahmad AlSa'deh and Hosnieh Rafiee

WinSEND is an implementation of IPv6 Cryptographically Generated Addresses (CGA), RFC 3972, and SEcure Neighbor Discovery (SEND), RFC3971, for Windows families (Windows XP/Vista/7). WinSEND is a user-space implementation to do CGA and SEND functionalities, such as CGA generation/verification, signature generation/verification, and X.509 certificate processing. WinSEND has direct access to Network Interface Card (NIC) and efficiently handles NDP messages by using Winpcap. WinSEND works as a service which requires minimal user interactions and configurations. The user can set SEND parameters, such as security level (Sec) and RSA key size for selected NIC. 1 WinSEND: Windows SEcure Neighbor Discovery WinSEND is developed by using Microsoft .NET. WinSEND supports the following RFC RFC3971, RFC3972, and RFC3779 (a simple certificate verification mechanism is provided. Please refer to related RFCs for more details about SEND protocol and related algorithms.

2nd place: MultiFS

Wouter Coene

MultiFS uses IPv6 multicast to distribute changes made to a set of files to multiple computers. Comparable to a distributed filesystem, but more of a distributing filesystem.

3rd place: GNUnet for IPv6 Peer-to-Peer Networking

Philipp Tölke, Matthias Wachs, Bartlomiej Polot and Christian Grothoff

GNUnet is a P2P framework developed by the Free Secure Network Systems Group at Technische Universität Mü̈nchen and many other committed contributors. The framework is free software and pro- vides abstractions to ease the implementation of new P2P applications. GNUnet is designed with a strong focus on security and uses link encryption between peers. It has a low-level transport service support- ing multiple transport protocols which facilitate P2P communication via TCP, UDP, HTTP, HTTPS and other protocols. GNUnet provides various routing al- gorithms including a DHT, support for NAT traversal, and extensive utility libraries to enable platform- independent application development. To benefit from modern multicore architectures and to improve fault isolation, GNUnet is divided into so-called services. A GNUnet service realizes a specific functionality and is implemented as an op- erating system process that makes a particular API accessible via IPC. Examples of services implemented within GNUnet are the transport services (providing low-level network connectivity), the core service (providing link-encryption), and the filesharing service. A more detailed description of the framework can be found in.

1st place: Efficient In-band Service Announcement Through IPv6 Address Encoding

Christian Hübsch, Christoph P. Mayer and Martin Röhricht

The announcement and discovery of network ser- vices represents one of the most important functionalities in today’s networks. In order to find and use services provided by remote systems, service management and dedicated service discovery protocols are used. These mechanisms introduce, however, additional overhead, especially in resource-constrained environments such as sensor networks. In this paper, we propose an in-band service announcement mechanism through IPv6 address encoding. In this scheme, IPv6’s large address space is used by a system to encode its service information into the host part of its IPv6 address. This information can then be extracted and efficiently used by other systems, allowing for service announcement without the need for additional protocols.

2nd place: Cloud Connect

Maximilian Weigmann

Cloud Connect behandelt Lösungsansätze für das Problem Zugriff auf Cloud
Services bei unzuverlässigen oder schmalbandingen Client-Anbindungen.
Mit Hilfe einer P2P-basierenden "Client Cloud" kann Zuverlässigkeit
verbessert und Bandbreite effektiver genutzt werden.
IPv6 bietet Möglichkeiten zur Realisierung der Client Cloud mit
Mobile IPv6 oder Routing-Mechanismen.
Die P2P-basierende Client Cloud kann auch in Ländern hilfreich sein,
deren Netz-Infrastruktur sich erst im Aufbau befindet.

3rd place: Optimierte Navigation mit IPV6 über Mobilfunknetze

Jörg Lauwigi

Diese Idee beschreibt die Möglichkeiten, die sich für die mobile Navigation durch die Verwendung von IPV6 über die Mobilfunknetze zwischen einer geeigneten Server- Infrastruktur und entsprechenden Userequipment ergeben können. Mittels IPV6 sind signifikant verbesserte Verkehrsprognosen möglich und eine unmittelbare Reaktion auf Ereignisse auf der gewünschten Strecke und dadurch eine deutliche Optimierung der Verkehrsflüsse.
