OPT-2041	Architecture and Design of Optical Transport Networks
Tuesday 10:00 am - 12:00 pm; Wednesday 10:00 am - 12:00 pm
Service providers and enterprises looking to deploy a flexible transport for deployment of Ethernet services face a number of options, often causing confusion as to how these transport options are to be built. This session discusses the technologies used in the design of optical transport networks for the deployment of data, storage, video, and Ethernet connectivity services. It includes an introduction to Gigabit Ethernet, 10 Gigabit Ethernet, coarse-wavelength division multiplexing (CWDM), dense-wavelength division multiplexing (DWDM), Resilient Packet Ring (RPR), and Synchronous Optical Network/Synchronous Digital Hierarchy (SONET/SDH) used as transport mediums. The session will also explore architectures (point-to-point and ring) and deployment guidelines for how to build these networks. Network Architects, Designers and Engineers who would be designing and deploying Optical Transport networks.

OPT-2044	Design Principles for Metro Optical Networks
Tuesday 10:00 am - 12:00 pm; Thursday 1:30 pm - 3:30 pm
Over the past few years the characteristics of metropolitan dense wavelength division multiplexing (DWDM) networks have evolved considerably. This session presents the underlying principles and best practices to successfully deploy complex optical systems. A few years ago, a typical Metro DWDM system had 16 x 2.5 Gbps channels, 200-GHz spacing, and unamplified spans. Now, the average system supports 32 x 10 Gbps, 100-GHz spacing, optical amplification, and chromatic dispersion compensation to cover distances of over 200 km and metro DWDM systems under development will raise the bar even further with respect to channel densities and distances. This growth process poses new challenges to the design of metro DWDM networks, as the impact of optical noise, chromatic dispersion, polarization model dispersion, and fiber nonlinearities must be carefully assessed to evaluate the optical performance of such systems. This session is designed to be particularly useful for network designers interested in the transmission aspects of metro optical networks. Although the session reviews basic optical technology concepts, it is designed as an intermediate-to-advanced course.

OPT-2045	Deploying Metro Ethernet: Architecture and Services
Tuesday 1:30 pm - 3:30 pm; Thursday 1:30 pm - 3:30 pm
This session focuses on new and innovative Ethernet services from a service attributes perspective, and explores the implications of these Ethernet services with respect to availability, security, quality of service (QoS), IP Multicast, and scalability from a user perspective. This session also discusses Layer 2 VPN Service Interworking that extends Ethernet services to existing technologies. Finally, the session discusses standards efforts that are underway within the IETF, MEF, and IEEE, such as the Ethernet LMI [NOTE: EXPAND ACRONYM] and operations, administration, maintenance, and provisioning (OAM&P), that are relevant to the development of Ethernet as a ubiquitous LAN, MAN, and WAN service. Network Architects, Designers and Engineers who need to understand more about implementations of Metro Ethernet.

OPT-4040	Advanced Technologies for SONET/SDH Metro Optical Infrastructure Deployment
Tuesday 10:00 am - 12:00 pm; Thursday 10:00 am - 12:00 pm
The continued growth of IP-based, bandwidth-intensive applications, along with the rising need to deliver carrier-class service-level agreements (SLAs), has created an interest in using optical infrastructures for scalability, resiliency, and investment protection. This has increased efforts focused specifically on integrating Ethernet-over-SONET (EoS). To date, these implementations have been proprietary and have been unable to provide interoperability between products and vendors. This session discusses advanced developments in integrating data and optical networks, including: -Enhanced quality of service (QoS) -Architectural considerations such as .1Q, QinQ, Ethernet over Multiprotocol Label Switching (EoMPLS), and Layer 2 Tunneling Protocol Version 3/Universal Transport Interface (L2TPv3/UTI) -Encapsulation techniques such as Generic Framing Procedure (GFP) and X.86 -Transport optimization mechanisms such as Resilient Packet Ring (RPR), Synchronous Transport Signal (STS) bandwidth scaling, virtual concatenation, and Link Capacity Adjustment Scheme (LCAS). These advancements are leading the industry towards common delivery of data over SONET/SDH. This session reviews the technical underpinnings of these advanced developments and shows how they contribute to the multiservice network's efficiency, scalability, resiliency, and interoperability. This session is designed to be particularly useful for metro optical network designers, architects, and engineers.
