DFNInternet at a Glance

With the DFNInternet service, we provide participating institutions with an internet protocol (IP) communications service. Using DFNInternet, members can access the X-WiN research network, all other cooperating research networks around the globe, as well as all other subnetworks in the internet (IP-transit).

DFNInternet is oriented to the specific, challenging needs of the scientific community. DFNInternet is oriented towards the needs of the most challenging projects in science and has been consistently designed for high data transmission rates as well as low latencies and runtime fluctuations. Real-time applications, such as VoIP and video conferencing services are also well supported.
