Converged, Dynamic Transport Networks

Brian Savory , ADVA Optical Networking, Inc.

Constantly expanding demands for network bandwidth continue to drive the adoption of multi-wavelength optical technologies in metropolitan and regional core transport networks. Simultaneously, the ubiquity and economics of Ethernet access devices are driving demand for efficient, reliable delivery of Ethernet-centric services. The combination of bandwidth demand, cost advantage and new applications is driving the emergence of a new generation of transport networks comprised of three specific technologies: reconfigurable DWDM optical transport, carrier-grade Ethernet service delivery, and the unified GMPLS-based network control plane. This session describes the many new data plane and control plane technologies emerging to enable construction of converged Optical + Ethernet transport networks and provides examples of how these technologies can be combined with existing reconfigurable DWDM transport elements and Ethernet access devices to form a new, unified transport network architecture. The advent of new optical transport elements with Layer 2 awareness, combined with Ethernet delivery elements with improved service awareness and OA&M capabilities, has the potential to significantly alter how metro and regional transport networks are deployed and managed. This session intends to provide members of the R&E community with a solid understanding of the options and benefits provided by a converged Optical + Ethernet transport network.

Optical Network Control Plane and OTN Reference Charts

Jim Archuleta , Ciena

Ciena will illustrate and outline two key technologies that serve as building blocks for dynamic research network connectivity between research institutions worldwide. A key ingredient to this challenge is the optical switching and optical control plane technology which places "intelligence" in the optical layer by automating configuration, provisioning and restoration of the network. Ciena's poster submission will outline the key features of the ASON /GMPLS control plane as well as standards that support an optical control plane and how it enables mesh networking, automated neighbor discovery, configuration and restoration, and dynamic lightpath provisioning. Additionally Ciena will provide a reference chart for the ITU G.709 OTN (Digital Wrapper) standard which adds significant value in OAM&P to optical networks.

Managing Data Center Power & Cooling: The Greening of the Data Center

Debbie Montano , Force10 Networks

Optimizing the overall power efficiency of high performance computing and data centers requires a comprehensive approach that focuses on technologies and strategies to minimize power consumption and maximize power efficiency at every level within the infrastructure, including CPU chips, power supplies, servers, storage devices, and networking equipment. In addition to measures that maximize power efficiency for hardware devices, there are also software strategies, such as server virtualization, that can play a significant role in reducing power consumption. There are a number of potential benefits that can be derived from an increased focus on power consumption and power efficiency: Extending the life of existing data centers and HPC centers and minimizing retrofits; Gaining at least partial control of growing expenses for power and cooling; Optimizing new data center designs to be more energy efficient.


Manjuel Robinson , Fujitsu

When deploying high capacity ROADMs, sub-wavelength grooming is necessary, to support low- capacity end-to-end circuits while still handing a large number of wavelengths. Some wavelengths are needed to support sub-wavelength Layer 1 or Ethernet connections. Various approaches exist to map and manage these sub-wavelength connections efficiently, including subtended equipment or integration of the grooming capability into the ROADM equipment. In the case of the integrated approach, there are segmented and non-blocking technologies that can accommodate either or both Layer 1 or Layer 2 traffic. This session will discuss various methods and the associated issues, tradeoff and benefits of the integrated approach and related bandwidth management.

Recent Advances in Photonic Integrated Circuits (PICs) Enable Cost-effective Network Scaling

Rick Hafey , Infinera Corporation

Sustained bandwidth growth and emerging high speed services (40/100G) are spurring optical network deployments with a strong focus on capacity scaling and lower cost per bit. This poster summarizes how PIC technology enables cost-effective and flexible optical transport networks compared to solutions based on multiple, complex discrete optical components. The poster describes exciting PIC technology advances and highlights PIC evolution beyond today?s commercially deployed 100 Gb/s PICs. Future PIC based transport systems will incorporate higher capacity PICs (400 Gb/s and higher), higher data rates per channel (40 Gb/s), integrated optical amplification and longer reach - all of which drive network costs lower and simplify network operations.

Internet Congestion and Multicast to Storage

Charles Hwa , Intercast Networks Inc.

Intercast Networks is developing a delivery solution for video over the internet that uses Multicast infrastructure to push a large volume of data to end user storage for later consumption. Building unicast video infrastructure will require an order of magnitude increase in the total cost of infrastructure ownership (TCO), to be borne by the consumer, the network operator, or the service provider. Multicast-to-Storage (M2S) offers a solution to video content delivery that can handle next generation video traffic, requiring orders of magnitude less bandwidth in order to transmit the same amount of unique content, and turning personal storage into personalized video on demand. Intercast Networks is looking for Universities to work with Intercast on research of university student video consumption, and study the effects of a multicasting solution on student video consumption online, as well as how this type of service may impact student behavior with regards to pirated content and peer-to-peer services. Intercast is also offering Universities membership to the M2S Development Group, a user forum to help guide the research and Beta trials. The poster will feature a schematic of the Intercast system, documenting the differences in unicast delivery, multicast delivery, and the multicast to storage solution.

Live HD Video over I2: Technology Demo and Business Case Analysis

Wes Simpson , Media Links

Most HD signals are transported from source to destination today in highly compressed form, which can introduce problems ranging from excessive delay to compression artifacts that can interfere with the video signal. By using light compression over high bandwidth networks, users can deliver production quality HD signals with extremely low delay. These advances open up a number of technical and commercial opportunities, including: 1) Two-way HD videoconferencing and live interviews. 2) Live sports and conference coverage on major networks. 3) Campus-wide connectivity to commercial video carriers. This poster session will include a live demonstration of a video link from Texas A&M to the Crystal City Marriott that will be carrying HD content at a bandwidth of 300-400 Mbps. The link will be artificially degraded through the use of a network impairment generator, and the effects of high-efficiency packet re-send technology will be shown on an HD monitor in the poster session area. The poster will include a complete description of the technologies employed and the actual test results. In addition, the targeted commercial application for transmitting live sports from campus venues to the PoP of a commercial video services provider by way of the LEARN network will be described, including a comparison to normal remote satellite technologies for this application.

European project to 'slice up' networks for research

Peter Szegedi , TERENA

Researchers who would like to conduct disruptive experiments, that shape the future Internet and other network infrastructures, will soon have a safe and flexible 'environment' for their work. A new European project called FEDERICA will create 'slices' of network infrastructure, which can be allocated to researchers as a virtual resource for their experiments. FEDERICA is the Federated E-infrastructure Dedicated to European Researchers Innovating in Computing network Architectures project. It will create a scalable, Europe-wide, technology-neutral infrastructure combining the approaches of network and system virtualization. This will be based on the multi-gigabit research and education network resources and will provide virtual slices dedicated to the resources to use in experimental activities testing new Internet architectures and protocols. FEDERICA?s virtual slices may even be allocated for disruptive experiments within a large production substrate. Internally the project will focus on understanding and producing solutions for monitoring, management, and control of parallel virtual networks in a multi-domain environment.

A Better VidyoConferencing Experience

Adi Regev , Vidyo, Inc.

Even as video communications have become more integral to enterprise applications over the past few years, the limitations of the current crop of video communications solutions have become uncomfortably apparent. Beyond the expense of the systems and solutions themselves ? not to mention the special rooms and dedicated networks these systems require ? users have been forced to bear with decidedly marginal performance, choppy frames, long delays, blurred motion, broken pictures, and the like. Given the expense of these systems, people have had good reason to expect more. And now those expectations will finally be realized. Allow us to introduce you to VidyoConferencing products that deliver higher-quality experiences and greater deployment flexibility and all at a lower cost over general-purpose IP networks. VidyoConferencing products are built on top of a better technical foundation than all those other video conferencing solutions namely, the H.264 Scalable Video Coding (SVC) standard. What?s more, a full range of user environments is provided for extending all the way from the home-office desktop up to the dedicated corporate video-conferencing facility. VidyoConferencing products have all been designed to take advantage of an organization?s existing IP infrastructure with no dedicated networks required. And yet Vidyo still manages to surpass the quality of video communications as we've known them to date and at just a fraction of the cost. By addressing the performance, cost, ease-of-use, and networking issues associated with traditional conferencing solutions, Vidyo has at long last made broad-based video communications affordable for both enterprises and consumer applications alike.
