ADVA Optical Networking
ROADM | Brian Savory
As bandwidth consumption continues to explode in a challenging economic environment, service providers and enterprises need to maximize their network’s efficiency – deliver more with less. Effective use of Reconfigurable Optical Add Drop Multiplexers (ROADMs) are key to this strategy. However, the ROADM landscape is large and diverse, and all the available technologies and architectures can at times be confusing and potentially prevent an operator from maximizing their networks’ potential. This poster details the three most common ROADM architecture types, dynamic, colorless, and directionless, while demonstrating the advantages of a building block approach to ROADM configuration.
100GE | Brian Savory
The development of 100GbE, like 10GbE and 1GbE before it, is being driven by bandwidth exhaustion. At first glance, the development cycle of 100GbE seems to mirror earlier 10GbE and 1GbE efforts. However, 100GbE differs from past Ethernet generations as there appears to be universal demand across all distances. The local caching of data, cloud computing, social networking, the PDA revolution, as well as a wide host of other trends have all conspired to shorten the average distance a packet travels. Today, there is an urgent and universal need across all distances for 100GbE transport. Currently, standards bodies are focused on short reach interconnect and very long reach transport implementations of the 100GE protocol. If a variation of coherent NRZ-DP-QPSK provides a solution for LH 100GbE transport and the 802.3ba standard offers suitable short reach options, what should a customer use at access and metro distances? The LH solution strikes an optimal cost/performance balance for LH, but it is not cost-efficient for regional distances shorter than 600km. If you relax requirements regarding spectral efficiency, you can omit polarization multiplexing and employ Xary ASK or DPSK modulation. This poster describes DPSK-3ASK modulation for cost-efficient 100GE WDM transport over distances less than 600km.

Building Cost Effective Optical Transport Networks | Ken Verch
This poster will focus on technology advances in optical transport that are allowing for the construction of more cost effective networks. There are a number of key capabilities being made available in the optical transport market more recently that contribute to lowering the cost of building out an optical transport network. These capabilities are either new capabilities or improvements on past technologies that have enabled them to be more generally deployed in the industry. Many of these technologies are particularly of interest for campus or regional networks. These capabilities are not just focused on capital savings in optical transport equipment. Many of them are focused in addition on savings derived by the need for less infrastructure like fiber or "huts" in which to house remote amplifiers. This session is intended to provided members of the Internet 2 community with the knowledge of the options that are available to them to cost effectively build out their own transport networks.
Optical Network to deliver services in rural areas | John Walker
We will review a case study of the optical network deployed by Grant County Public Utility District to provide high-speed internet, television, telephone, wireless and power to 15,000 homes in rural Washington state. It is an example of the types of networks encouraged by the ARRA legistlation passed earlier this year.
Juniper J-Net, Social Networking and the R&E Community | Debbie Montano
Juniper Networks not only provides the building blocks for R&E networks with switches, routers and security, Juniper is also embracing and taking leadership on social media, online communities, blogs, twitter, facebook, social bookmarks and rich media. Come learn how you can connect with the Juniper J-Net community and other sites and venues where Juniper is active -- and provide your feedback on where and how you'd like to see Juniper further engaged with the online collaborative R&E community.

In August 2009, the Virtual School of Computational Science and Engineering sponsored two week-long workshops ("Scaling to Petascale" and "Many-Core Processors") for graduate students whose research emphasized some aspect of high-performance computing (HPC). The students traveled to one of four participating sites (CCT@LSU, NCSA@UIUC, NICS, and UMich; and EVL@UIC, NCSA@UIUC, OSC@OSU, and UMich; respectively). An instructor at one site delivered a lecture to the students at all sites simultaneously via high-definition (HD) videoconferencing technology. Alternate lectures were given by instructors at alternate sites. Altogether half the sites participated as presenting sites at one time or another during the workshops. <p> The students at all sites (not just the presenting site) engaged the instructor in synchronous question-and-answer (Q&A) sessions. In addition, threaded discussion groups were provided for asynchronous Q&A at any time during the week. For the webcast students who participated remotely, only asynchronous Q&A was provided. <p> This poster presentation will depict the technology used (including the backup technology) and the procedure used to facilitate synchronous Q&A via HD technology. Of particular importance is the coordination, preparation, and testing that preceded the workshops, and the lessons learned that will be applied to future workshops.
Scalable and Economical 10, 40 and 100G Networking | Thomas Zawistowski
Metro Ethernet Networking (MEN) solves the challenges of 40G transmission by using QPSK encoding at 10GBaud. Two QPSK signals are employed in this solution. Each QPSK signal is modulating one of the two orthogonal polarizations of a single optical carrier. This method is called dual polarization (2-POL) QPSK. With this modulation technique, 40G and 100G transmission can be achieved using 10G-like electronic and optoelectronic components, and optical impairments will be equivalent to those in a 10G system. The receiver employed in this solution is a fully coherent receiver; the incoming signal is mixed with a local oscillator and then detected. A coherent receiver preserves the necessary characteristics of the signal to allow the QPSK decoding to be effected successfully. After high-speed and high resolution analog to digital conversion, the signals are discriminated against and tracked using a unique, dynamic, highspeed digital, CMOS-based signal processor developed by Nortel. Therefore, migration from 10G to 40G or 100G Requires NO disruption to the existing fiber network because of: Ð Significantly superior CD tolerance to 10G networks, with integrated electronic dispersion compensation technology, eliminating the need for DCMs Ð Better PMD tolerance than 10G networks, eliminating the need for external PMD compensators Ð Equivalent Optical Signal-to-Noise Ratio (OSNR), eliminating the need for Raman amplifiers ¥ Is scalable and can operate in 50- GHz-spaced systems ¥ Maintains complete agility required to meet ever-changing service requirements with flexible OADM/ROADM support ¥ Is less expensive than 4 independent 10G signals

This is a program RADVISION is currently rolling out to the Internet2 community. It is a phased approach, starting with site coordinators, moving to private virtual rooms for selected universities and then a pay-for-use roll out.
IPTV trial update |
Walt Magnussen, Texas A&M | Shaun Illingsworth, Move Networks
For the past two years we have been working towards an IPTV solution that would ride the Internet2 backbone. It is envisioned that a service offering would be available to any Interent2 member and SEGP members with sufficient bandwidth. When offered, the services will include standard television programming, international content, specialized educational content and pay-per-view services.
This (poster/session) will provide an update of the current IPTV trial that includes approximately 20 member universities, supported by the Texas A&M University Internet2 Technology Evaluation Center (ITEC), Move Networks and Internet2.
VidyoRouter: Enabling VidyoConferencing for the Internet that Works Like the Internet | Ben Pinkerton | Greg Thener
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.
