100Gbps for NexGen Content Distribution NetworksMartin Zirngibl, Alcatel-LucentPresentation Date: January 26, 2009, 2:30 PM - 3:00 PMRoom: La Fiesta Theatre Abstract: Video and content distribution will be the main bandwidth driver for access and metropolitan networks forcing network operators to upgrade transport capacity by an order of magnitude over the foreseeable future. To support such a massive build-out, 100Gbps will be required to lower both CAPEX and OPEX while adapting to demands of service domain interconnects. 100Gbps presents some unique challenges because transport technologies that have been used at 10Gbps and 40Gbps cannot be simply scaled to 100Gbps. In this talk, we will review some of the basic technology choices that have to be made for building cost effective, high performance, and reliable 100Gbps transport networks. We will start by reviewing the modulation formats for 100Gbps and discuss their cost and performance related trade-offs. As we will show, a coherent modulation, which is the optical equivalent to a FM car radio, presents the best choice for 100Gbps to have sufficient reach and be compatible with today’s 10Gbps/40Gbps Wavelength Division Multiplexing transmission (WDM) systems. While making 100Gbps affordable, yet without footprint penalty, the industry must adapt a new level of integration. We will show how Photonic Integrated Circuits (PIC) have the potential to achieve our goals. Furthermore, we will discuss the architectural impact of video in conjunction with 100Gbps technology. In particular, we will show an innovative architecture that take advantage of the unique characteristics of video traffic’s asymmetry and bursts. Martin Zirngibl Biography: Martin Zirngibl is currently head of the physical hardware research domain at Bell Labs, Alcatel-Lucent. Martin joined Bell labs in 1990 after receiving a PHD in applied physics from the Ecole Polytechnique Federal, Lausanne, Switzerland (EPFL). At Bell Labs, he worked on various optical technologies such as fiber amplifiers, photonic integrated circuits and fiber-to-the-home access architectures. He has won several multi-million dollar DARPA contracts in optical packet switching. More recently he led the research efforts in 100GbE. Archived Files: NANOG45 Abstracts
