Short Course 216: An Introduction to Optical Network Design and Planning
Instructor: Jane M. Simmons, Monarch Network Architects
Location: Los Angeles Convention Center, Los Angeles, California
Date/Time: TBD
Description:
This course is an introduction to optical network design and planning for backbone, regional, and metro-core networks. A fundamental aspect of any optical network design is selecting the proper network elements to maximize flexibility and adaptability for future growth, while minimizing cost. The course discusses the role of network elements, such as ROADMs, multi-degree ROADMs, and optical switches, and describes where each element fits in a network. It addresses the benefits of equipment features such as ‘colorless’ and ‘directionless’. Various case studies illustrating technology tradeoffs are presented.
Routing and wavelength assignment play an important role in the efficiency of networks based on these optical elements. The course covers the principles of routing and wavelength assignment, including a description of some of the relevant algorithms. The role of regeneration and optical reach in network design is discussed in some detail. Modeling for real-time planning is also covered.
Many of the principles of the course are illustrated through an interactive design session with a commercial optical network design tool.
The course has also been expanded into a book: Optical Network Design and Planning

Title: "Diversity Requirements for Selecting Candidate Paths for Alternative-Path Routing"
Conference: OFC/NFOEC 2010
Author: Jane M. Simmons, Monarch Network Architects
Abstract: In alternative-path routing, it is shown that requiring candidate paths to be diverse only with respect to the most congested links in the network performs better than requiring the candidate paths to be completely diverse.

Title: "Nodal Architectures for Shared Mesh Restoration of IP and Wavelength Services"
Journal: IEEE Photonics Technology Letters
Author: Jane M. Simmons, Monarch Network Architects
Abstract: Future networks are expected to support heterogeneous traffic, including both IP and wavelength services. IP services are typically restored using IP-layer rerouting mechanisms, whereas wavelength services are restored in the optical layer. With architectures where IP services are mapped into Layer-2 or TDM protocols at the network edge, a common restoration mechanism can be utilized for both IP and wavelength services. This paper examines various nodal architectures that can be utilized to support such a unified restoration paradigm.

- OFC/NFOEC 2009 Symposium: The Future Internet and Its Impact on Next-Generation Optical Networks
Held on March 24, 2009, at the San Diego Convention Center, San Diego, California
Organizers: Adel A. M. Saleh, DARPA and Jane M. Simmons, Monarch Network Architects
Description: The Internet continues to evolve with innovative applications, increasing bandwidth requirements, changing traffic and usage patterns, and debates over policy. This evolution is clearly intertwined with the performance and economics of the underlying optical networks. This symposium will explore the future Internet, and how it will impact the architecture and technology of next-generation optical networks, from the backbone core to the access edge. Several leaders in the field will present their visions and predictions; they will then respond to questions and comments from the audience.
