SC216 - An Introduction to Optical Network Design and Planning
Sunday, 19 March
13:30 - 16:30
Short Course Level: Beginner
Jane M. Simmons; Monarch Network Architects, USA
Short Course 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 equipment to maximize scalability and configurability, while minimizing cost. The course will discuss the role of network elements, including ROADMs, multi-degree ROADMs, and ‘Drop-and-Waste’ ROADMs, and address the benefits of equipment features such as ‘colorless,’ ‘directionless,’ ‘contentionless,’ and ‘gridless.’
Routing and wavelength assignment (RWA) play an important role in the efficiency of ROADM-based networks. The course will cover RWA principles, including a discussion of some of the most relevant algorithms. This includes topics such as routing for cloud-computing applications and wavelength assignment in multi-line-rate networks. The role of regeneration and optical reach in network design will be discussed. Modeling for real-time vs. long-term network planning will also be covered.
The course will address current areas of research in optical networking, including: gridless and elastic optical networks (EONs), routing and spectrum assignment (RSA), network defragmentation, power consumption, Software Defined Networking (SDN), and strategies to address fiber capacity limits, including Space Division Multiplexing (SDM).
Many of the principles of the course will be illustrated through an interactive design session with a commercial optical network design tool.
Short Course Benefits:
This course should enable you to:
Compare O-E-O and optical-bypass technology.
Compare the architectures of various optical network elements.
Describe the colorless, directionless, contentionless, and gridless attributes of ROADMs.
Describe the basics of routing traffic, including strategies for load balancing and protection.
Describe the basics of wavelength assignment.
Enumerate some of the networking principles as well as physical effects that determine where regeneration is required in a network.
Enumerate the advantages and disadvantages of Elastic Optical Networks (EONs).
Discuss the ‘hot’ topics in network architecture, including Software Defined Networking (SDN), power consumption issues, and Space Division Multiplexing (SDM).
Short Course Audience:
This course is intended for network planners and architects in both carriers and system vendors who are involved in planning optical networks and selecting next-generation optical equipment. The discussion of networking elements and algorithms, as well as the discussion of current research areas, should be helpful to vendors who are developing optical systems and to carriers who are modeling network evolution strategies. The course is introductory level, although a basic understanding of networking principles is assumed.
Jane M. Simmons has been involved in the research and development of optical networks for more than 15 years. She founded Monarch Network Architects, which provides optical network architectural services and design tools. From 1999 to 2002, she was the Executive Engineer for Network Architecture at Corvis Corp., and was named the Chief Network Architect in 2002. While at Corvis, she performed the network design and the link engineering for the Broadwing network, the first commercially deployed all-optical backbone network. Through pioneering algorithmic and architectural optimizations, she played a significant role in the adoption of all-optical networking in telecommunications networks. Prior to Corvis, Dr. Simmons worked at Bell Labs/AT&T Labs Research, where she conducted research on backbone, regional, and broadband access networks. She received a B.S., Summa Cum Laude, from Princeton University, and S.M. and Ph.D. degrees from MIT, all in Electrical Engineering. She is a Fellow of the IEEE and is the author of the textbook Optical Network Design and Planning, now in its second edition.
