With the G-Lab project, a Germany wide research community and experimental facility platform is built up to investigate the interplay between new technologies and the requirements of emerging applications. Funded by the German Federal Ministry of Education and Research (Bundesministerium für Bildung und Forschung - BMBF), the project consists of 32 partners. The first phase had started in October 2008 with six partners. Since 2009, the Computer Networking Technology Group is involved in the second phase of the project. For more information, see https://www.german-lab.de

G-Lab DEEP researches innovative composition approaches for the cooperation between network and service levels with focus on security in the Future Internet. To evaluate the developed concepts, we use and extend the G-Lab platform. In this project, we develop qualified tools and frameworks to establish communication workflows for secure voice communication and multimedia-based applications in the Future Internet. Furthermore, the project investigates possibilities for a secure federation with other internationally relevant Future Internet experimental platforms, e.g. FIRE / GENI. Enhancing the G-Lab platform is an important aspect of this project and provides capabilities for future-oriented experimental research in the context of the G-Lab project. For more information, see http://www.g-lab-deep.de

We as the Computer Networking Technology Group of University Duisburg-Essen are performing research in the context of the G-Lab DEEP in the following work packages:

• Work Package 1.2: Scenarios 
  In this work package, we define relevant communication scenarios taking into account Functional Composition as workflow and cross layer approaches to security. As starting point for these investigations, we selected the Voice-over-IP (VoIP) and multimedia communication based on the Session Initiation Protocol (SIP). On one hand, voice and multimedia services are highly relevant and challenging for the Future Internet. On the other hand, relevant data is already available on service characteristics and threat scenarios, which makes theses services ideally suited for our research.  For the definition of possible attack scenarios we exploit the detailed knowledge on real attack patterns gained in our VoIP Honeypot project. 
  Based on these scenarios we define cross-layer attack detection and mitigation schemes. The demonstration of our scenario established for first phase of the project has been presented at the EuroView2010.  The scenario is available at EuroView2010 Demo. For the second phase of the project, we defined a new scenario that will be demonstrated at the EuroView2011 in Würzburg and is available at EuroView2011 Demo. 
• Work Package 2.2: Service Layer Functions for Anomaly and Fault Detection 
  Based on the scenarios specified in work package 1.2, we define monitoring and detection mechanisms in this work package. In particular, we already developed a distributed sensor system detecting SIP attacks based on the predefined attacks patterns from WP 1.2. Our system not only automatically detects and identifies the specified attacks but also allows user interaction to enable user feedback on specific calls and to the system for the current threat state.  By reporting the detected anomalies to an Intrusion Correlation and Aggregation Center, the collected information can be provided to the network level and the respective mitigation mechanisms can be triggered. Furthermore, the efficiency of the system can be considerably enhanced by accessing and exploiting the information collected at the network level.  Hence, a distributed cross-layer detection system will be the result of our activities in WP 2.
• Work Package 3: Defense and Mitigation 
  In this work package lead by our group, defense and mitigation mechanisms addressing both the network and service level are developed based on the detection system designed in WP2.  Specifically, we design a filter system that mitigates the attacks at the service level and allows user interaction to enhance and calibrate the scheme. By cooperating with the mitigation schemes implemented on the network level, a comprehensive protection can be achieved.

• WP 4.1: DEEP Boot Image 
  In contrast to other experimental platforms G-Lab offers the possibility of using alternative boot images. Therefore, we extend the G-Lab platform currently based on PlanetLab Software by creating a specific boot image providing additional functionalities.  One of the additional functionalities we provide is a Multi-Homing capability for G-Lab nodes. The other one is the possibility of realising more complex network topologies in G-Lab by introducing routing functionality in G-Lab nodes. Specifically, we deploy the additional functionalities and evaluate them in the context of experiments with load sharing over multiple network paths. These experiments are based on our research related to extensions of the Stream Control Transmission Protocol (SCTP).

In addition to projects, several SIGs have been formed in the context of the G-Lab.  Within these SIGs, researchers with similar research interests meet exchange their results for potential co-operations. In the context of the G-Lab, we lead the following SIGs:

• Security This group established in (here year) should bring together the research interests in the network and communication security.  For more information, see https://www.german-lab.de/wiki/sig/security/start.
• Multipath Researchers having interests in multi-path transfer aspects meet in this group, which has been established in 2010. In addition to meetings within G-Lab conferences, we organised the first G-Lab Multipath Meeting in Essen on 19.11.2010. For more information, see https://www.german-lab.de/wiki/sig/multipath/start.

• In addition to the SIG Multipath, we organise the 2nd International Workshop on Protocols and Applications with Multi-Homing Support (PAMS), in conjunction with the 26th IEEE International Conference on Advanced Information Networking and Applications (AINA) in Fukuoka/Japan in March 2012. For more information, see http://www.tdr.wiwi.uni-due.de/workshops/pams-2012/welcome.
• Also, in addition to the SIG Multipath, we have organised the 1st International Workshop on Protocols and Applications with Multi-Homing Support (PAMS), in conjunction with the 25th IEEE International Conference on Advanced Information Networking and Applications (AINA) in Singapore in March 2011. For more information, see http://www.tdr.wiwi.uni-due.de/workshops/pams-2011/welcome.
