GES3 - Grid Enabled Scalable Self-Organizing Services
A Vinnova-funded research project 2004-2006


Goals and purpose






Project background

In recent years researchers at SICS, KTH, and around the world have studied a new class of distributed algorithms, based on distributed hash tables (DHTs). They allow the creation of structured overlay networks or peer-to-peer networks for organizing large-scale distributed applications. Unlike traditional server-centric solutions DHT-infrastructures are decentralized, scalable, self-organizing, and inherently robust in the face of failures, attacks and high peak loads. The results of this research, though for the most part based on large-scale simulations of distributed directory services (discovery), are extremely promising. So promising, that researchers are beginning to speculate that the next-generation large-scale distributed applications will be based on DHTs. Based on previous work on DHTs by SICS and KTH in other projects we now propose to take the next step, to build, experiment and validate real systems.


The project is organised in two parts. One is headed by SICS and KTH (see GES3 at SICS) and the other (this one) is headed by Truvé & Vasell Innovation. The SICS/KTH project is mainly focused on further research and development of the DHT-infrastructure, whereas this project is focused on the use of a DHT infrastructure in real applications.

Project goals and purpose

The overall purpose of the project is to investigate the applicability of the DKS framework (the DHT infrastructure developed by SICS and KTH) in a realistic application. As our application domain we have chosen services which are parts of a platform for network-based defense, the NBF-core, being developed by Ericsson Microwave Systems.

More specifcally we have started out by devloping a name service on top of DKS. The name service plays a central and critical role in the NBF-core as being the repository for information regarding services available in the network.

Project status

The first version of the name service is now running on the DKS framework.

We are now planning a series of tests an evaluations which will give us insight into the characteristics of the our name service implementation.


Besides Truvé & Vasell Innovation AB, the following partners are active in the project:
