12. Session Abstract
While the deployment of the new 100Gig Internet2 Network provides an opportunity for the Internet2 community to redefine advanced networking for research and education, it also presents many universities and connectors with a challenge -- how to cost effectively deploy 100 Gbps transport infrastructure from their respective campuses to access the nearest Internet2 hub. This panel discussion will review practical, cost-effective solutions for enabling 100 Gbps wavelength connections from research & education networks to the Internet2 backbone. The advanced modulation for 100 Gbps optical transport enables 100G wavelengths to be easily added to existing 10 Gbps DWDM systems. See which vendor solutions support this functionality. The monthly recurring cost operating expenses of colocation (i.e. space, power, cooling, etc.) can, over time, outweigh the capital costs of equipment. Learn how the various vendor solutions address these factors. Come see which vendor solutions are compatible with 100GHz and 50GHz DWDM modulation schemes and can operate on any available wavelength within current 40- and 80-channel DWDM wavelength plans. Discussion topics to include: • What are the current network topologies and equipment options for implementing 100Gbps access connections? • Learn how incremental cost per Mbps of bandwidth is impacted with 100Gbps versus the cost for existing 10G systems. • What is the typical reach using the new 100Gbps coherent detection solutions? • Which vendor solutions can be configured as a muxponder or transponder thereby aggregating and/or transporting any mix of 10 Gbps, 40 Gbps and 100 Gbps services over a 100 Gbps OTN connection?
