1. IP telephony : Mobility and security
Abstract : With the introduction of IP based telephony services, the Internet has started to challenge the traditional PSTN networks as an infrastructure for providing real-time interactive services. This upcoming paradigm shift is not only driven by the desire to provide cost efficient solutions, but by basing the communication on IP we expect that the end-users will experience a greater set of attractive services over a single connection compared to what is provided by a PSTN today.

2. Hybrid Routing in Next Generation IP Networks : QoS Routing Mechanisms and Network Control Strategies
Abstract : Communication networks have evolved from circuit-switched and hop-by-hop routed systems into hybrid data/optical networks using the Internet as a common backbone carrying narrow- and broad-band traffic offered by a multitude of access networks. This data/optical backbone is built around a multi-technology/multi-protocol routing architecture which runs the IP protocols in a collapsed IP stack where ATM and SONET/SDH have been replaced by the suite of Generalized Multiprotocol Label Switching (GMPLS) protocols.

3. TCP/IP technology for modern network environments
Abstract : To facilitate the merging of wireless access technologies and the traditional Internet, the core protocols for data communication should be robust and have low overhead. In this thesis, we propose refinements to the Transmission Control Protocol (TCP) that improve its cost efficiency over wireless links. READ MORE

4. On the Design of Next-Generation Routers and IP Networks
Abstract : This thesis investigates distributed router architectures and IP networks with centralized control. While the current trend in IP-router architectures is towards decentralized design, there have also been research proposals for centralizing the control functions in IP networks. READ MORE

5. Design Principles for Network Distributed Denial of Service Defense
Abstract : People, organizations and society are become more and more dependent upon access to Information Systems. Most Information Systems are accessible via the Internet. It is becoming easier and easier to perform successful network attacks against these Information Systems, which causes the system to become unavailable for its intended users. READ MORE
