SWITCHlan: the smart data network

SWITCH has been networking the academic community since 1989. SWITCHlan connects universities with each other and with the Internet. In addition to the data network itself, SWITCH offers everything users need to make the most of it.

A factor of 800,000

The definition of a good communications network has hardly changed in decades. It needs to be suitable for every application and available all the time. The range of applications and the performance of the hardware in use, on the other hand, have changed dramatically and continue to do so. This means that networks continually face new challenges. When SWITCHlan first appeared back in 1989, the maximum connection bandwidth was only 128 kilobits per second. That was enough to cope with all the applications available at the time. Today, it's up to 100 gigabits per second. That, too, is enough for all applications – for now.

More than just a data network

SWITCHlan is more than just a smoothly functioning data network for universities. It's a unique blend of infrastructure, transmission technology, quality assurance, lab testing, assistance, transparency and partnerships. In addition to the infrastructure, SWITCH offers useful network services and a dedicated customer service team to help universities make the most of the network.

Forming an integral part of the academic community, it commits its resources to innovation. The SWITCHlan team is thus open to ideas for experimental projects. It's no coincidence that SWITCHlan forms the basis for a large number of central SWITCH services, including SWITCHaai.
