ⓘ MHSnet

MHSnet is a store-and-forward M essage H andling S ystem for wide area net works. MHSnet and its precursor, SUN3, were used to implement the Australian Computer Science network, commonly known as ACSnet, which connected Australias Universities to each other and to ARPANET.

MHSnet was originally developed at the University of Sydney by Piers Lauder and Bob Kummerfeld and was originally known as SUN3 Sydney University Network version 3. Technically, it is similar in concept to UUCP in that it enabled the transfer of email, Usenet, and files in an efficient manner over non-dedicated links. In addition, it supported dynamic routing and a hierarchical name space avoiding the limitations of hardwired network addresses.

MHSnet was a key technology in the introduction of Internet access in Australia. Due to the prohibitive costs of telecommunications structure, and the small amount of bandwidth available both internally and to other countries, MHSnet provided a system that could more efficiently use network resources. Gateways between ACSnet and the Internet were provided by many universities, and access to non-academic users was granted in the early 1990s.

In 1989, with the introduction of AARnet which directly connected Australias Universities to the Internet, the ACSnet and MHSnet became obsolete.

ACSnet connected hosts in Australia resided in a.oz domain, which was moved into the Internets.au namespace as.oz.au.
