- 030.50.3 The view from the Gigabit networking World
- by David J. Farber <farber@central.cis.upenn.edu>
-
- In subsequent issues of the ISOC Newsletter, this column will cover specific
- research issues and accomplishments of both the NSF/DARPA/CNRI Gigabit Testbeds
- Initiatives and other gigabit network related research activities. This first
- contribution is timely since it is concurrent with the passage of the US HPCC
- bill. The US testbeds, Aurora, Blance, CASA, Nector, and VISTANET are an
- ongoing activity now in the second year of a three year initial program. It
- aims are to provide a set of experimental testbed of different characteristics
- with the intent of allowing the research community to have the opportunity
- create and explore working prototype networks. This would in collaboration with
- other research activities provide feedback to the hardware and software
- designers as to what the long term technical requirements would be for a future
- gigabit NREN.
-
- This will provide an insight into the hardware/software alternatives that must
- be faced in the creation of the Gigabit NREN as envisioned in the HPCC bill. It
- is not the intention of the testbeds to have a bakeoff of technology. . We will
- have a handful of major switch designs, some ideas of what we have to do with
- protocols and operating systems -- for example the National Backplane ideas,
- the application level protocols, the speed up of TCP/IP, ATM, PTM etc. These
- approaches will not be examined in order to "pick one" but rather to get a
- better handle on the fundamental issues. At the end of the initiative we will
- be where the Arpanet was back in the mid 70's -- a working set of demos, some
- protocol ideas and lots of enthusiasm.
-
- And finally and most importantly, I believe we will have a good enough feel for
- the benefits of gigabit networks to the science community, that we will be able
- to answer the question we should be asking -- is such a network a reasonable
- use of limited science resources?
