- Within Australia the Australian Academic and Research Network (AARNet) provides
- infrastructural internetworking services to the broad national academic and
- research community.
-
- The network interconnects all 38 higher education institutions, the divisions
- of the Commonwealth Scientific and Industrial Research Organisation and also
- provides connection services to sectors of the national and state governments
- and various governmental and commercial organisations. AARNet currently
- supports some 22,000 connected end user host systems and supports a user
- population of in excess of 100,000 people, drawn predominately from the
- academic and research domain. The network was established in May 1990.
-
- The internal structure of AARNet is based on the deployment of multiprotocol
- routers and point to point leased serial lines. Internal capacity of the links
- ranges from 2Mbps on the major internal trunk routes to 48Kbps for tail loops
- and a number of low speed 9.6kbps tails. The major networking protocol in use
- across AARnet is the TCP/IP protocol suite. A national Phase IV DECnet is also
- supported (this network does not use addressing modes which allow direct DECnet
- connectivity to the HEP/SPAN DECnet) and regional X.25 switching facilities are
- also supported within the transport infrastructure. The namespace of Australian
- nodes is within the national top level domain ".au".
-
- The major international facility is a satellite link to the US Federal exchange
- point on the West Coast, Fix-West. From this point direct connectivity is
- established to a number of other Asia / Pacific national networks, and through
- connections within the national US infrastructure connections to the remainder
- of the global Internet are established. Additionally AARnet supports
- international mail connections to Papua New Guinea and Thailand.
-
- AARNet is operated by the peak national university body within Australia, the
- Australian Vice-Chancellors' Committee. The facility is funded directly by the
- user community through institutional participation in the program.
-
- More information on services and facilities available within AARNet can be
- retrieved via the anonymous ftp facility from the host aarnet.edu.au. Documents
- held there include a resource guide of Australian resources and copies of
- periodic newsletters and informational publications from AARNet.
