Latest Optical Transport Technologies for the R&E Community

Session Abstract

The access network, providing secure, scalable and reliable connectivity to CAI's is a critical element of today's network infrastructure. The access network must be able to transport enormous amounts of data driven by today's video, cloud computing and other bandwidth-intensive applications. Today's network managers must be able to address the question: how quickly can our access network respond to growing and changing demands? This session will compare alternatives for providing cost effective hi-cap network community anchor institution access connectivity to core optical broadband networks. The session will provide a recommended 'best fit' for CAI access alternatives, highlighting tradeoffs between optical Ethernet and DWDM access technologies and service architectures. 1. Session speakers will specifically address the following topics: a. Optical Ethernet b. 1 Gbps Ethernet c. 10 Gbps Ethernet d. L2 vs. L3 tradeoffs e. Hierarchical traffic management (class of service assignments) f. Differentiated service capabilities - Low latency forwarding - EPL, EVPL (MEF certified) - Link performance management & reporting (for service level agreements) - Y.1731 (delay, jitter, throughput, etc) - Remote Ethernet access circuit test & turn-up capability, RFC 2544 (opex savings) Optical DWDM access alternatives a. 10 Gbps b. 100 Gbps c. Coherent vs. non-Coherent tradeoffs d. How to close the 10-100 Gbps significant cost delta e. Integrated 10x1 Gbps Ethernet extension muxponder f. Encryption considerations
University and research campuses' networks are more complex than ever before. The growing need to move bandwidth-intensive services is driving the demand for increased capacity. Dense Wavelength-Division Multiplexing (DWDM) is a traditional technology for scaling network capacity, but for many it's far from optimal. While fixed DWDM-based optical layers may be cheaper to install, they're becoming much more expensive to manage and maintain over the long run. To enable the network to scale, today's fixed optical layer requires expensive, user-intensive procedures and significant pre-planning. Instead of viewing the network as a group of independent elements, operators can now integrate a dynamic optical layer that combines two innovative elements for an evolutionary network. First, fourth-generation ROADM delivers several previously separate ROADM functions into a single integrated module-a critical step in creating a simple, cost-optimized network solution. Second, with full 'plug-and-play' capabilities, a highly integrated and compact DWDM line amplifier continuously monitors the line and dynamically adjusts power levels as required. Together, these technologies simplify the network provisioning process and deliver significant value at all stages of service delivery-from installation to operation-to yield a strong return on investment and guarantee service delivery for campuses now and in the future.
