When Internet2 was organized in October 1996, one defining mission was to
provide scalable, sustainable, high-performance networking in support of the
research universities of the United States. The resulting infrastructure,
comprised of campus, regional, and national components, is succeeding and yet
must evolve over time.
In planning on the Internet2 networking infrastructure needed beginning 2006,
we are aiming at designing and building a hybrid of shared IP packet switching
and aggressive use of dynamically provisioned optical lambdas. We use the term
HOPI (for hybrid optical and packet infrastructure) to denote both the effort
to plan this future hybrid and the set of testbed facilities we will build to
test various aspects of candidate hybrid designs.
The eventual hybrid will require a rich set of wide-area lambdas with IP
routers and lambda switches capable of very high capacity and dynamic
provisioning, all at the national backbone level. Similarly, we are working
now to encourage the creation of RONs (for regional optical networks) by the
same consortia that currently operate the gigaPoPs that connect our campuses
to Abilene. Finally, the planned hybrid infrastructure will require new forms
of campus LANs.
To enable the testing of various hybrid approaches, we are building the HOPI
testbed, making use of resources from Abilene, from the RONs, and from
National LambdaRail (of which Internet2 is a key participant). A HOPI design
team, composed of engineers from Internet2 member universities, is currently
planning this testbed in detail.
