Network Security: Private Communication in a Public World
Dr Radia Perlman, Sun Microsystems
This tutorial covers the concepts in network security protocols, describes the current standards and vulnerabilities, and suggests areas that need research. It approaches the problems first from a generic conceptual viewpoint, covering the problems and the types of technical approaches for solutions. It gives a tutorial introduction to cryptography, and then describes the kinds of network security that can be built using cryptography. For example, how would encrypted email work with distribution lists? What are the performance and security differences in basing authentication on public key technology versus secret key technology? What kind of mistakes do people generally make when designing protocols? Armed with a conceptual knowledge of the toolkit of tricks that allow authentication, encryption, key distribution, etc we describe the current standards, including Kerberos, S/MIME, SSL, Ipsec, PKI, and web security.
About Dr Perlman
Radia Perlman's work has had a profound effect on the world of networking. She designed the spanning tree algorithm used by bridges, and many of the key algorithms that make link state protocols (IS-IS, OSPF) robust, manageable, and scalable. Her work has also been seminal in routing security and tangible computing. Recent contributions include secure digital shredding of data, strong password protocols, transparent routing, scalable PKI-based cross-organizational authentication and authorization, and analysis and redesign of IKE (the authentication handshake for IPsec). One of her missions is to get people to think critically about networking, rather than just memorizing the details of what happens to be currently deployed, or believing everything they hear or see in print. Titles of recent talks she has given include "How to build an insecure system out of perfectly good cryptography", "Things we all know about network protocols that aren't true", and "Miss Manners Meets the IETF".
She is currently Distinguished Engineer at Sun Microsystems Laboratories. She is also a series advisor for Prentice Hall, and serves on both the routing and security directorates of IETF.
She is the author of "Interconnections: Bridges, Routers, Switches, and Internetworking Protocols", and coauthor of "Network Security: Private Communication in a Public World". Both books are popular both with engineers and as university textbooks. She has taught graduate and undergraduate level courses at Harvard, MIT, and University of Washington. Holding approximately 70 patents, she was named Silicon Valley Intellectual Property Law Association's 2004 Inventor of the year.
Radia Perlman has a PhD in computer science from MIT and an honorary doctorate from KTH, the Royal Institute of Technology, Sweden.
Internet Routing: Measurement, Modelling, and Analysis
Dr Matthew Roughan, University of Adelaide
The Internet consists of millions of independent systems (routers and hosts). Communication between these is controlled by the largest scale distributed calculation made on our planet. This computation is based on routing protocols whose dynamic behaviour has been observed to be highly complex, and cannot currently be predicted. The Border Gateway protocol (BGP) is the current defacto standard inter-domain Internet routing protocol. It glues the Internet together, but is also used by service providers to implement policies, and perform traffic engineering to control inbound and outbound traffic across multiple locations and lins. BGP has evolved over the years with additions of new protocol features, such as support for MPLS based VPNs. It is therefore important to understand the performance issues of the current protocol by developing appropriate monitoring and analysis methodology. Given that the health of BGP along with that of tightly coupled intra-domain protocols such as OSPF and IS-IS have a significant impact on the performance of applications, the measurement, modelling, and analysis of Internet routing protocols is an important topic. This tutorial covers topics related to BGP policies, routing dynamics, measurement, and modelling, focusing on introducing the basic operations of BGP sufficient to understand the robustness, complexity, performance issues.

Image Processing using FPGAs
Dr Donald Bailey, Massey University
FPGAs are increasingly being used as an implementation platform for real-time image processing applications because their structure is able to exploit spatial and temporal paralellism. However, mapping an image processing algorithm onto hardware is not a trivial task as many of the development tools are relatively low level. The introduction of parallelism, and meeting timing, resource, and bandwidth constraints often necessitates a significant change to the form of the algorithm to achieve an efficient implementation. The development process is made more difficult as the large volume of data from real-time images makes debugging difficult. These issues are discussed in the context of mapping of some common image processing operations onto FPGAs.

Dr Mahendra Chilukuri, Multimedia University, Malaysia
Time- Frequency Signal Processing has been successfully applied in many fields of engineering in the recent past especially real-world applications involving non-stationary signals. Some of the interesting applications are interference excision, seizure detection, speech recognition and data compression. However, these techniques have more potential applications in medical as well as machine diagnostics in near future. This tutorial discusses some of the recent time-frequency algorithms from fundamental with suitable examples using Matlab programming. Also, a few case studies of recent applications of time-frequency signal processing in Power Quality, Machine Condition Monitoring and Medical Diagnostics will be discussed.
MPLS and GMPLS: Principles, Implementation, and Advanced Concepts
Alton Lo and Mallik Tatipamula, Cisco Systems
MPLS and GMPLS are fundamental building blocks for today's evolving networks. Switch and router manufacturers as well as Service Providers are looking to MPLS and GMPLS to leverage new revenue streams, to provide new services, and to extract better performance and capacity from their existing equipment. In order to offer competitively differentiated services, it is necessary to understand the basic principles of the protocols, how they are implemented and deployed, and their advanced capabilities.
This tutorial will start by reviewing the fundamental concepts in MPLS, MPLS-TE and GMPLS, and will highlight the key components of these protocols. It will then describe some aspects of the software implementation of the protocols drawing on the presenters' wide experience of different implementations, switches and deployments to highlight some of the common pitfalls and misconceptions.
The final section of the tutorial will focus on advanced applications and latest developments in MPLS and GMPLS networks. It will cover:
- Extending the existing protocols to provide end-to-end service across multiple network domains. This includes establishing connectivity between TE tunnel endpoints by providing capabilities to setup tunnel that spans across different IGP areas or Autonomous Systems.
- Network failure protection and recovery schemes to support simultaneously mission-critical applications and dynamic, reliable signaling and control for optical transport network infrastructure and voice/video services.
- Operations and Management (OAM) features that are essential to ensure the correct functioning of the network.
- New developments including Error and Alarm Reporting, Layer One VPNs, and Interworking with the ITU-T's ASON architecture.

Accurate Modelling of IPv4 and IPv6 Protocols with OMNeT++ Simulation Framework
Dr Ahmet Sekercioglu, Monash University
Discrete event simulation is now a well established method for teaching and research on network modelling, analysis and optimization. In an education environment, experimenting with different network protocols and configurations allows students to gain insight into the performance tradeoffs involved in the design of networks. In a research environment, performance analysis of increasingly complex network topologies and quanititative studies of the interactions of a mix of network protocols via simulation helps researchers to complete projects much faster. In the past, researchers have had to either rely on custom made simulators that were specifically designed for their own requirements or choose among the commercially available (and sometimes very expensive) tools. Also, licensing restrictions have prevented free exchange of developed models. Nowadays there are freely available, open source discrete event simulation tools with varying degrees of sophistication.
OMNeT++ (Objective Modular Network Testbed in C++), a leading open source network simulation tool (which is free for research and educational purposes), is among the very best in terms of quality of its architecture, documentation, scalability features, and availiability of graphical animation and debugging tools. OMNeT++ is primarily designed to simulate computer networks, multiprocessors and other distributed systems, has a well-defined API (application programmer's interface) and allows designing arbitrarily nested hierarchical modules which promote model reuse. Another major advantage of OMNeT++ is its protability between Windows (XP, NT, 2000) and Unix based systems, its NED (Network Description Language) compiler for topology description, and the use of parameter watching functions and plotting capabilities.
OMNeT++'s use is increasing in IPv4 and IPv6 related research in academia, and also in commercial environments for a wide spectrum of projects and products. In this tutorial, we aim to introduce the capabilities of OMNeT++ for IPv4 and IPv6 research. We will cover several examples from our own IPv6/MIPv6 work and introduce the models starting from very simple ones to quite sophisticated WiFi mesh network simulations. The first part this tutorial will introduce OMNeT++'s functionality. The second part aims to make the attendees familiar with TCP/IP protocol simulations, and to understand the importance of simulation in testing and validation of communication protocols. The third and fourth parts of the tutorial focus on the design of packet switched network simulation models. Emphasis will be given to modelling of IPv4, IPv6 and Mobile IPv6 networks.

OFDM for Broadband Wireless Communications: Fundamentals, Applications and Implementation Challenges
Dr Jean Armstrong, Monash University
Fundamentals
The tutorial will begin with an overview of the basic principles of OFDM (Orthogonal Frequency Division Multiplexing) including the format of the transmitted signal and a simple description of the main components of an OFDM transmitter and receiver. Some of the important characteristics of OFDM will be described including its resilience in the presence of multipath and its resistance to impulse noise.
Recently, OFDM has been combined with MIMO, multiple antenna techniques. Basic MIMO OFDM configurations will be described, and the reasons why OFDM and MIMO make such a powerful combination will be explained. OFDM is also proposed for a number of emerging technologies such as UWB and cognitive radio. In these applications, the spectrum of OFDM can be tailored to avoid interfering signals.
Applications
The applications of OFDM can be broadly categorised as broadcast applications such as digital television broadcasting, point to multipoint applications such as wireless LANs and WiMax and emerging technologies such as UWB and cognitive radio. The development in each of these areas will be described and the aspects of OFDM which are important in each case will be highlighted.
Implementation Challenges
Despite the many advantages of OFDM, it presents many implementation challenges. The receiver must achieve frequency, symbol and sampling synchronisation. The multipath channel must be accurately estimated. OFDM has a high peak to average power ratio. This means that many parts of the transmitter and receiver must have a wide dynamic range, analog components must be very linear and fixed point digital components must be carefully designed.
