SC176 - Metro Network Evolution
Monday, 12 March
09:00 - 12:00
Short Course Level: Advanced Beginner
Loudon Blair, David Krauss; Ciena Corp., USA
Short Course Description:
Metro networks are being stretched by cloud and video streaming services that are forcing the capacity of customer access links to increase by two to three orders of magnitude. Data centers and content caches are proliferating across metro areas as hosts for new services and applications. Because service revenues are not growing in proportion to bandwidth, new network solutions are needed to dramatically lower the cost per unit bandwidth of the network infrastructure. Consequently, service providers almost universally have migrated away from legacy SONET/SDH to new metro infrastructures based on IP, Ethernet and optical technologies. In this course, we review new service trends for both residential and business environments and we analyze how these new services are changing network traffic characteristics across the metro area. We then explore resulting metro network architectures and examine the mix of technologies that can be employed to yield highly functional yet economic network solutions. This includes an introduction to IP, Carrier Ethernet and optical services, and how supporting implementations are evolving in order to achieve desired performance. New metro network architectures and evolving service use cases are explored.
Short Course Benefits:
This course should enable you to:
Describe how new services are changing metro network traffic characteristics.
Explain the impact that these new services will have on metro network traffic patterns and network architectures.
Differentiate between the meaning of IP, Ethernet and optical ‘services’ versus IP, Ethernet and optical ‘infrastructure’.
Identify the key networking technologies used to build next generation metro networks, including DWDM, OTN, Ethernet and IP/MPLS.
Describe how packet and optical technologies are converging to implement efficient networks.
Discuss different metro application scenarios, including evolving distributed cloud network architectures.
Short Course Audience:
This course is intended for network architects and planners from service providers, engineering and marketing staff to network equipment providers, technologists with an interest in the evolution of networks, industry analysts, and financial analysts.
