Managing Information Technology

Some commentators have referred to the Internet as
the “information superhighway.” That is wrong, as Bill
Gates, the cofounder and former CEO of Microsoft, pointed
out in his 1995 book, The Road Ahead(Gates, 1995). The
Internet is merely the predecessor of the information
superhighway; we are not there yet. Before we have a true
information superhighway, we need gigantic increases in
bandwidth, more reliability and security, more accessibility
by the entire population, and more applications. We are
only beginning to scratch the surface of possibilities for the
Internet and the information superhighway beyond.


INTERNET2 In reality, Internet2is not a network type,
although it does run a leading-edge, very high-bandwidth
network; it is a not-for-profit consortium of over 200 U.S.
universities, working in cooperation with 70 leading
technology companies, 45 government agencies and labo-
ratories, and over 50 international partner organizations, to
develop and deploy advanced network applications and
technologies. Internet2 hopes to accelerate the creation of
tomorrow’s Internet, a true “information superhighway.”
The three primary goals of Internet2 are to



  • create a leading-edge network capability for the
    national research community

    • enable revolutionary Internet applications based on a
      much higher-performance Internet than we have
      today

    • ensure the rapid transfer of new network services
      and applications to the broader Internet community




Until 2007, Internet2’s “leading-edge network for
the national research community” was named Abilene.
Then in 2007, Internet2 rolled out a new, even higher-
performance network, with the appropriate but neverthe-
less confusing name Internet2. The original version of the
Internet2 network was an extremely high-performance
digital optical network, with all the links in Figure 3.10
operating at 100 gbps—10 times the capacity of its
predecessor Abilene network. Then the Internet2 network
was upgraded again to include several robust, logically
different, but related networks, each on its own overlaid
infrastructure: an advanced Internet Protocol (IP) network
provided by Juniper Networks routers, a Virtual Circuit
network provided by the switching capabilities of the
Ciena CoreDirectors (optical switches), and the Core
optical network based on Infinera’s optical networking
platform. In addition to Juniper Networks, Ciena, and
Infinera, other partners in building and operating the
Internet2 network include Level 3 Communications, who
