DNSSEC

The original design of the DNS (Domain Name System) contained no security. The emphasis was on creating a scalable and distributed system. DNSSEC (Domain Name System Security Extensions) tries to add security while maintaining compatibility with the existing standard.

Time service

DeiC operates a time service based on the NTP standard (Network Time Protocol).

The current time may be fetched from ntp.forskningsnettet.dk, a Stratum-2 server.

Forskningsnettet also has access to a Stratum-1 server, that may be used for e.g. synchronizing local time servers.

Domain Name Service

Institutions on forskningsnettet, the Danish national research and education network, may choose to use DeiC name services.

DeiC operates an authoritative name server and a secondary name server. It is also possible to use the forskningsnet name servers as secondary to a local name server - with or without DNSSEC.

DeiC also operates a number of DNS caches that users may query directly. They can also be used as backup for a local name server. Caches are situated at:

Ericsson to deliver optical transmission equipment for Danish NREN

Five vendors competed for the contract to supply optical transmission equipment for forskningsnettet, the Danish National Research and Education Network (NREN) run by DeiC. Ericsson won together with its partner, ECI Telecom.

The new equipment is set to replace Alcatel equipment which has been operating since 2008. The new equipment allows for data rates at 100 Gbit/s. The existing gear may be configured with up to 40 channels per connections, whereas the new equipment allows for 88 channels.

Tender for optical transmission equipment re-opened

The request for tender was originally issued in December, but too few vendors submitted requests to participate. Therefore, the process was stopped. It has now been restarted.

DeiC expects to spend between DKK 18 million and 30 million on optical transmission equipment for Forskningsnettet, the Danish National Research and Education Network.

The procurement process has three steps:

First, a number of potential vendors are selected. DeiC expects to select five vendors.

Next, the vendors submit their proposals. Finally, DeiC selects a vendor.

FileSender

FileSender lets you save, send and share files through a web-based interface. You use WAYF for authentification to the service. Authenticated users may e-mail an upload voucher to guest users.

FileSender supports almost all devices and operating systems. You need to have Adobe Flash version 10 or later. If you wish to send files larger than 2 GB, your browser needs to support HTML5.

English

Multicast

The multicast service makes it possible to send large amounts of data such as video, TV and streaming between many different users at the same time without putting excessive strain on the network. The philosophy behind multicast is that data only once has to pass one link – regardless if there are 1 or 100, who wish to receive the data.

Forskningsnettet supports multicast, but as there often are many obstacles like firewalls, multicast does not play any important role among the services. The obstacles also mean that you have to make a thorough test before using it.

Name service

  • Forskningsnettet in DeiC hosts a authoritative name server with a supplementary secondary name server. Institutions connected to DeiC may use these servers for their domains. It is also possible to use the name servers at Forskningsnettet as a secondary for a local name server – with or without DNSsec. Please contact dns@deic.dk

  • Forskningsnettet runs some DNS caches which can be used for queries made directly from the users’ equipment. They can also be used as backup for a local name server.
