SC216 - An Introduction to Optical Network Design and Planning
Sunday, 05 March
09:00 - 12:00 (Pacific Time (US & Canada), UTC - 08:00)
Short Course Level: Beginner
George Rouskas, North Carolina State University, 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, especially 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 protection. 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: elastic optical networks (EONs), Software Defined Networking (SDN), open and disaggregated optical networks, low-margin optical networks, cognitive optical networks, and space division multiplexing (SDM).
Short Course Benefits:
- 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), open optical networks, low-margin optical networks, cognitive optical networks, 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.
