From ARPANET to LambdaGrid: The 1980s Eruption
• 1985 – NSFNET Key Decisions– NTAG
• To appoint a technical advisory group to advise (and, more generally, to build consensus among the US academic research community)
– General Purpose Network:• to develop a general purpose national network for all
(science and engineering) research, not just a specialised network for supercomputer users, in order to achieve the mission goals - i.e. to provide all of the science and engineering research community with access to supercomputing power (and by extension to all researchers/academics)

From ARPANET to LambdaGrid: The 1980s Eruption
• 1985 – NSFNET Key Decisions– An Internet:
• to develop a network of networks – an Internet – rather that a dedicated single supercomputer network.
– TCP/IP:• to adopt the TCP/IP (DARPA) protocol suite – the
Internet protocols. • to mandate that the TCP/IP protocol suite be adopted (in
due course) by all existing supercomputer networks funded by the NSF’s Advanced Scientific Computing programme.

(e.g. CSNET, BITNET), ARPANET, and – a national backbone network - linking the national
supercomputer centres/networks (and through them the regional and campus networks).
