Tutorial 1: Scheduling algorithms for input-queue IP routers

Sunday May 26, 12:30 - 15:30

Tutor
Marco Ajmone Marsan (Politecnico di Torino)
Paolo Giaccone

Syllabus
This tutorial discusses the issues involved in the design of schedulers for input-queued switching matrices, within high-performance IP routers.
The goal of the tutorial presentation is to first illustrate the motivations for input-queued switching matrices controlled by simple and efficient scheduling algorithms within high performance routers, and then overview some of the most significant scheduling algorithms that were recently proposed in the technical literature.
The performances of all overviewed schemes are discussed through numerical simulation results as well as theoretical statements about their stability properties.
The tutorial is destined to researchers in the field, as well as designers of high speed router architectures.

Tutorial 2: Peer-to-peer communications

Sunday May 26, 12:30 - 15:30

Tutor
Takashige Hoshiai (NTT)

Syllabus
Gnutella's announcement in March 2000 stirred worldwide interest by referring to a P2P model. Basically, the P2P model needs not the broker?the centralized management server?that until now has figured so importantly in prevailing business models, and offers a new approach that enables peers such as end terminals to discover out and locate other suitable peers on their own without going through an intermediary server.
This tutorial explains P2P concepts and visions from the viewpoints of P2P history and dimension model.
Takashige Hoshiai proposed a Brokerless Model (similar to P2P model) back in 1998, based on SIONet (Semantic Information-Oriented Network) as the implementing technology. Prototype version a of SIONet was developed in 1998, followed by prototype version b in 1999, and versions 1.0 SIONet in the year 2000.
SIONet is essentially a meta network based on an autonomous decentralized collaboration scheme. In contrast to conventional networks that require a destination address for packets to reach their proper destinations, packets are delivered in SIONet based on semantic information.
This enables entities to discover for and zero in on other specific entities in the vast sea of distributed non-specific entities that are connected to the Internet. This tutorial explains SIONet technologies and makes a demonstration using SIONet prototype

Profile
Takashige Hoshiai is a senior research scientist supervisor at NTT Network Innovation Laboratories, in Japan. He holds a Ph.D. degree in Communications and Systems form The University of Electro-Communications, Japan.
His research areas are distributed systems, distributed object technologies, real-time systems, agent systems and P2P. Since he proposed Brokerless model in 1998, especially, he has studied SIONet architecture that is a solution of P2P platforms.

Tutorial 4: IP over WDM

Sunday May 26, 16:00 - 19:00

Tutor
Hussein T. Mouftah (Queen's Univ)

Syllabus
The emergence of Wavelength Division Multiplexing (WDM) technology has provided a new dimension for exploiting the huge capacity of optical fibers. WDM allows multiple optical signals to be transmitted simultaneously and independently in different optical (wavelength) channels over a single optical fiber and thus provides enormous bandwidth at the physical layer. With IP becoming the dominant network-layer technology for global networks, IP internetworking over WDM networks is becoming increasingly important. In order to fully utilize WDN Network capabilities, we have to develop new architectures and network control methods to import IP traffic into WDM highways while providing Quality of Service management in a cost effective way. We will discuss these issues and present the control models of IP-optical network interaction. We will also present the Generalized Multi Protocol Label Switching (GMPLS) and the role it can play in this area.
Network survivability has been a crucial concern in WDM optical networking. To survive different types of network failures, a variety of optical protection and restoration schemes have been proposed. We will address this issue and present different optical protection and restoration schemes within wavelength-routed WDM mesh networks. We will cover dedicated and shared protection schemes including path and link shared protection, short leap shared protection, as well as channel protection.
The deployment of wavelength converters within optical switches provides robust routing, switching and network management in optical layer, which is critical to the emerging all-optical Internet. However, the high cost of wavelength converters at current stage of manufacturing technology has to be taken into consideration when we design node architectures for an optical network. We will discuss the efficiency of wavelength converters in a long-haul optical network at different degrees of traffic load. Also, we will describe cost-effective ways to optimally design wavelength-convertible switch so as to achieve higher network performance while still keeping the total network cost down.
We will describe routing and wavelength assignment (RWA) algorithms and their use in the design of WDM networks with and without wavelength converters.
