JANET is a private British government-funded computer network dedicated to education and research. All further- and higher-education organisations in the UK are connected to JANET, as are all the Research Councils; the majority of these sites are connected via 20 metropolitan area networks across the UK. The network also carries traffic between schools within the UK, although many of the schools' networks maintain their own general Internet connectivity. The name was originally a contraction of Joint Academic NETwork but it is now known as JANET in its own right. It is linked to other European and worldwide NRENs through GEANT, has a private connection to its equivalent CERNET in China and peers extensively with other ISPs at Internet Exchange Points in the UK. Any other networks are reached via transit services from commercial ISPs. JANET is operated by JANET, formerly known as UKERNA, who are also responsible for the .ac.uk and .gov.uk domains. It is funded by JISC, the Joint Information Systems Committee.
