The 2009 Berkeley Nanotechnology Forum (http://www.ocf.berkeley.edu/~nano/events.php?view=18) is an all-day forum on Sunday, April 26. It's a great opportunity to learn more about nanotechnology today. Listen to views of top scientists, entrepreneurs and venture capitalists, and meet your fellow Bay Area and Berkeley community members spearheading research and innovation in the field of nanotechnology.
The theme for this year's forum is: "Solutions for Tomorrow." In addition to prominent speakers, the forum will feature a student poster session, showcasing the state-of-the-art research of the Bay Area researchers and students in nanoscience and nanoengineering.
This year's Nano Forum has been opened up to alumni for free admission. To register visit: http://nano2009.eventbrite.com/.

Transmission Mismatch
Recent advances in optical transport technologies have created a radical mismatch in networking between the optical transmission world and the electrical forwarding/routing world. Today, a single strand of optical fiber can transmit more traffic than the entire Internet core. However, end-systems with Data Intensive Applications do not have access to this abundant bandwidth. Furthermore, even though disk costs are attractively inexpensive, the feasibility of transmitting huge amounts of data is limited. The encumbrance lies in the limited transmission ability of Layer 3 (L3) architecture. In the OSI model, L3 provides switching and routing technologies, mainly as packet switching, creating logical paths known as virtual circuits for transmission of data from node to node. L3 cannot effectively transmit PetaBytes or hundreds of Terabytes, and has impeding limitations in providing service to our targeted e-Science applications. Disk transfer speed is fundamentally slower than the network. For very large data sets, access time is insignificant and remote memory access is faster than local disk access.
