Tutorial T1 8:30AM - 12:00PM
MPLS for Traffic Engineering
Multiprotocol Label Switching (MPLS) has been in development for over five years and is now being widely deployed in service provider networks. One of the first applications of the technology was to introduce sophisticated traffic engineering capabilities to IP networks using constraint-based routing. This tutorial will explain how traffic engineering and constraint-based routing are implemented using MPLS, and will also explore some of the newer applications of the technology. These applications include:
This talk is targeted towards network operators who are considering deployment of MPLS and towards developers who wish to gain a detailed understanding of MPLS technology. A basic level of familiarity with IP networking is expected.

Tutorial T2 8:30AM - 12:00PM
Description:In recent years, there has been an explosion of commodity networking technologies supporting gigabits per second bandwidth. However, the legacy communication protocols such as TCP/IP running over these gigabit networks have been able to deliver only a fraction of the network bandwidth to the application level. Similarly, the application to application communication latency has been quite high. In order to alleviate these bottlenecks, many User-Level Networking Protocols (ULNPs) such as AM, VMMC, FM, U-Net, LAPI, and BIP have been proposed by the research community. The development of these protocols have led to the industry standard of Virtual Interface Architecture (VIA) to be available in commercial systems. Currently, the VIA standard is being implemented on many systems. While these developments are on-going, the industry has already moved ahead in drafting the next generation communication and I/O architecture standard, called InfiniBand Architecture (IBA). This new architecture eliminates the PCI bus-based architecture and supports switched connections. It incorporates high performance I/O in addition to interprocessor communication, provides QoS and protection in the network, provides multiple transport services, and allows flexibility of IBA subnets to be connected to Wide Area Networks (WANs) through routers. The IBA standard incorporates VIA functions at its verbs layer.
This tutorial is intended to provide an in-depth overview of both VIA and IBA standards. It will demonstrate how high performance communication and I/O architectures for scalable systems can be designed with this standard by taking into account interprocessor communication, network communication, and communication to I/O devices. The basic components of the IBA standard and multiple layers of this architecture will be described in detail. The new functionalities associated with this standard such as Quality of Service, Protection Domains, etc., for designing large-scale enterprise servers will be discussed. The interactions among these components and their interactions with the host, OS, Network-Interface Card (NIC), router/switch, and I/O devices to support low-latency and high bandwidth interprocessor communication and I/O will be analyzed. Open research challenges in designing scalable IBA implementations and providing support for higher-level programming models (such as distributed memory, distributed shared memory, get/put, and sockets) on these systems will be outlined. The tutorial will conclude with an overview of on-going InfiniBand and VIA related research at universities, industry, and research labs.
This tutorial is intended for researchers, scientists, engineers, managers, developers, professors, and students engaged in research, design, and development of next generation communication and I/O architecture for enterprise servers as well as high-performance and scalable systems.

Tutorial T3 1:30PM - 5:00PM
Bluetooth Vs. 802.11
Description:The promise of untethered computing in the workplace is becoming a reality. IEEE 802.11b, the 11Mbps wireless LAN standard, has finally arrived, and early market response has been positive. As the WLAN market takes off, Bluetooth, another emerging standard for short-range wireless networking, is also gathering force. Several vendors have demonstrated Bluetooth products, including cordless headsets, PCMCIA cards, and LAN access points. Both standards are competing for the same airwaves, but are they also chasing the same market? Will Bluetooth and 802.11b complement each other, or will one technology eventually displace the other?
The tutorial is intended for researchers and practitioners who want to learn more about Bluetooth 1.1 and 802.11b standards. The tutorial will illustrate in what ways the two technologies are similar or different. Computer professionals who want to develop better understanding of technology trends and identify new market opportunities in the space of short range wireless networking will also benefit from this tutorial. Basic understanding of layered network architecture is expected. No background in analog radio, signal processing, or wireless communication is required. Researchers who want to identify open research problems in the area of personal area networking will also find this tutorial very useful.

Tutorial T4 1:30PM - 5:00PM
Control and Management of Modern Optical Networks
The Internet transport infrastructure is moving towards a model of high-speed routers and multi-service provisioning platforms (MSPP) interconnected via an intelligent optical network. The optical network consists of optical switches connected to each other with point-to-point DWDM links in a mesh configuration. A consensus is emerging in the industry on utilizing IP-centric control plane within optical networks to support dynamic provisioning and restoration of lightpaths. Specifically, it is believed that IP routing protocols and Multi-Protocol Label Switching (MPLS) signaling protocols could be adapted for optical networking needs. At the same time, there are divergent views on how IP routers must interact with optical core networks to achieve end-to-end connectivity. This tutorial will focus on modern optical transport network architectures, network elements involved in switching and transporting optical signals, and control and management of optical networks. It will cover the following topics.
