Research Projects of the Computer Networks Group

> Secure and Fast Re-establishment of IPsec Sessions in Failover Scenarios
IPsec gateways maintaining security associations (SAs) with a large number of remote access clients may take unacceptably long time to recover from gateway or network failures when all the clients were to use a full IKEv2 exchange to re-establish the SAs. This project studies and evaluates systematically a solution for IPsec session resumption to facilitate failover capabilities. more...

> Mobility and Routing in Future Internets
We study issues related to routing, traffic engineering, advanced mobility support and related issues in the future converged IP networks. more...

> PlanetLab - An Open Platform for Developing, Deploying, and Accessing Planetary-Scale Services
The Institute for Informatics is a member of the PlanetLab program. The Computer Networks Group collaborates with other research facilities (and researchers) in the PlanetLab consortium. more...

> TCPNP - TCP/IP Wireless Network Performance Enhancements
In this project we explore the potential of utilizing cross-layer interactions and hardware-software co-design to optimize the end-to-end TCP performance. Scalability and fairness, in addition to security and mobility support, will be a focus of the project. more...

> MING-T - Multistandard Integrated Network Convergence for Global Mobile and Broadcast Technologies
As we move towards an era of widespread information availability, an effective system of convergence among the new broadcasting technologies, Internet technology, and mobile systems becomes increasingly important. Countries are deploying multiple broadcast technologies; it will remain a key challenge for the industry and user communities to provide a uniform platform to content providers, and convergence is critical to overcoming this challenge. The goal of this EU FP6 IST Specific Targeted Research Project (STREP) is to research, develop, prototype, integrate and validate the interoperability and handover issues of the representative mobile digital broadcast standards developed in China and Europe. more...

> RoNeVi: Resilient, DoS-Limiting Overlays and Network Virtualization

> ENABLE - Enabling efficient and operational mobility and large heterogeneous IP networks
EU FP6 IST funded Specific Targeted Research Project. The goal of ENABLE is to research, develop, test, integrate and evaluate mechanisms and technologies for the deployment of efficient and operational mobility as a service in large scale IPv6 network environments, taking into account also the transition scenario from IPv4. more...

> DAIDALOS II - Designing Advanced network Interfaces for the Delivery and Administration of Location independent, Optimised personal Services
EU FP6 IST funded Integrated Project Daidalos II will design, develop and validate a blueprint of a true B3G Framework. It supports secure, personalized and pervasive services built on heterogeneous network and service infrastructures for the mobile user and will contribute to standards and industry fora. more...

> OPNET University Program
The Computer Networks group partners with OPNET Technologies, Inc. for research on network technologies. more...

> SIGNET - Development of New, Extensible Internet Signaling Protocols
This project develops communication protocols that can be used to provide various signaling services, such as Quality of Service resource reservation setup or firewall configuration in network nodes along the data path of end-to-end communications in IP-based networks. more...

Previous Projects

> PTLS - Performance Study of Transport Layer Security
In this project we investigate the issue of performance impact on difference protocol options for the IETF Transport Layer Security (TLS) protocol.

> VIDIOS - VIdeo DIstribution Over MPLS networks
The VIDIOS (VIdeo DIstribution Over MPLS networks supporting heterogeneous format environments) project develops, integrates and tests all parts of the "media chain" over wireless and wired broadband Internet access networks and Multiple Protocol Label Switching (MPLS) backbones.

> IPT - Internet Protocol Testing: Methodolody
ETSI project - Internet Protocol Testing: The project develops the framework and specifications for conformance and interoperability testing of IPv6 protocols, including general Internet protocol testing methodoloy, and test specifications for IPv6 core, security, mobility and v4/6 transition protocols.

> MobiAuth - QoS and Authentication Issues in IP Mobility
The technical focus of this project is research in the area of the QoS signaling, admission control, reservation schemes, authentication and other security issues for achieving seamless handover using IP mobility protocols. Currently we concentrate on QoS-aware authentication issues in mobile IPv6 and micro-mobility schemes like HMIPv6 and fast handover for MIPv6.
