T1 Description:

This is a short-course on WDM optical networks, devices and technology. It consists of five major units:

  • Optical and photonic concepts; including are the dual nature of light, refraction, diffraction, interferometry, holography, linear and non-linear optical medium properties, propagation of light in optical medium, loss, scattering, dispersion, polarization, polarization dispersion loss, four wave mixing, and many others.
  • Description of key photonic passive and active devices; including are filters, gratings, multi-mode and single-mode fibers, FBGs, polarizers, phase shifters, modulators, optical amplifiers (EDFA, Raman, SOA), optical switches, wavelength conversion, lasers (VCSEL, DBF, FP), and receivers.
  • The DWDM and CWDM channel grid and its characteristics according to ITU-T standards, and their applicability.
  • Transmission impairments and noise sources that affect the quality of the signal, BER and OSNR, and ramification strategies for dispersion compensation, polarization compensation, equalization and more.
  • Optical topologies, optical networks from access (including FTTP, metro (small, medium, large), mesh, and point-to-point with add-drop). In addition, this part includes system design, network protection strategies, survivability, static and dynamic switching and wavelength assignment, routing and wavelength assignment.
  • Introduction to next generation optical networks (Next-Generation SONET” and “Optical Transport Network”).

The course is supported by notes and optionally by four books authored by the instructor (published by IEEE/Wiley): “Introduction to DWDM Technology” (2001), “DWDM: Networks, Devices and Technology” (2003), “Next generation SONET/SDH” (2004), and “Optical Bit Error Rate” (2004).

Intended audience: No prerequisite is required. Basic knowledge in communications and optics will be helpful. This course is suitable to those requiring knowledge of advanced optical communications networks such as managers, technologists, optical communications technical support, scientists, and graduate students. 

T2 Description:

As communication needs evolve, the current optical network requires both synchronous and asynchronous traffic with enhanced efficiently, scalability, protection strategies, and performance-cost objectives. The next generation optical network is based on DWDM technology and is designed on new standard protocols to efficiently address these requirements. This network may be viewed as an amalgamation of the best concepts from legacy synchronous and asynchronous networks, adding to it new concepts that enhance network attributes including efficiency-cost.

This short course starts with a review of critical optical network topologies, the SONET/SDH standard and DWDM technology. It describes the next generation SONET/SDH, Data-over-SONET/SDH, Packet-over-SONET/SDH, error handling, protection switching, the Link Capacity Adjustment Scheme (LCAS), the Generalized Framing Procedure (GFP), the Link Access Procedure for SDH (LAPS), Internet and Ethernet over SONET/SDH, Virtual Concatenation (VC), Multi-Service Switching Platform (MSSP), Multi-Service Provisioning Platform (MSPP), Next Generation SONET/SDH over DWDM, as well as the Optical Transport Network (OTN).

This course is supported by notes and optionally by four books authored by the instructor (published by IEEE/Wiley): “Next generation SONET/SDH” (2004), “Understanding SONET/SDH and ATM” (1999), “Introduction to DWDM Technology” (2001), and “DWDM: Networks, Devices and Technology” (2003).

Intended audience: This short course is designed for general audience. It provides a synopsis of those protocols that are needed to understand the next generation optical network. Therefore, this short course becomes attractive to those that have a need for an overview of the next generation optical network, including managers, communications engineers, communications management and control, and network modeling.

T3 Description:

This tutorial provides an introduction to the Semantic Web and it technologies. The today World Wide Web is intended for the user to access and consume the contents but it provides little help to identify and locate the contents. To use the wanted contents the user must somehow obtain their URI (Uniform Resource Identifier). This justifies the popularity of Google. The Web is only intended to human being but not computer and it is therefore difficult to build software applications that can interpret, process and use the published content. The Semantic Web is a vision for the future of the Web in which information is given explicit meaning, making it easier for machines to automatically process and integrate information available on the Web. The tutorial will explain clearly the motivation of the Semantic web. The tutorial will provide an overview of the Semantic Web components which are XML, XML schemas, RDF, RDF schemas, DAML, DAML-OIL, and OWL.

Intended audience: Managers, engineers, scientists, and graduate students who want to understand the future Web and its technologies. 

T4 Description:

In this half-day tutorial, we will review network architectures for next generation optical Internet networks with special focus on the optical burst switching (OBS) paradigm. Due to the exponential increase of Internet traffic, IP (Internet Protocol) has become the convergence protocol for multi-service networks. On the other hand, WDM (Wavelength Division Multiplexing) point-to-point links are already in use by a multi-layer architecture to transport IP traffic. Although this approach increases the link bandwidth by using WDM, it does not solve the problem of network bottleneck due to the exponential traffic growth, since this solution only shifts the bottleneck problem from the link to the electronic router. A solution to this problem that also leads to lower management costs and lower complexity consists in the use of a two-layer architecture, in which IP traffic is transported directly over optical networks. This tutorial will focus the integration of IP protocol with the optical layer, in order to build the so-called optical Internet. Approaches proposed for the optical Internet, namely the Generalized MultiProtocol Label Switching framework conducted by IETF (Internet Engineering Task Force) and the OBS paradigm will be discussed. After presenting the most important optical switching paradigms, we will concentrate on OBS networks. Concerning OBS networks, we will consider network architectures, burst assembly process, classes’ reservation, resource reservation protocols, contention resolution, and QoS support. The recent technological developments and future trends are also discussed.
