Transmission Mismatch

April 12, 2009 by Tal Lavian, Ph.D.

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.

Gilder and Moore – Impact on the Future of Computing

Gilder and Moore – Impact on the Future of Computing
The principles of both Gilder and Moore are important phenomena that must be considered juxtaposed to Grid Computing infrastructure in new e-Science research. Moore’s Law predicts doubling silicon density every 18 months. In early 2000, a common misconception held that traffic was doubling every three months. Andrew Odlyzko and Kerry Coffman showed that this was not the case. He demonstrated that traffic has been approximately doubling every 12 months since 1997 based on progress in optical bandwidth. Gilder’s Law predicts that the total capacity of optical transport systems doubles every six months. New developments seem to confirm that optical transport bandwidth availability doubles every nine months.
