Live lecture streaming and capture by smartphones

Smart-phones only with standard wired hands-free has recently been applied as capturing devices to capture lectures with UNINETT IoUs experimental Live Streaming service, with reasonable success. Many cloud services support live streaming and recording from smart-phones (e.g. Justin.tv, Youtube, UStream, facebook,…) however they typically handle a single stream per channel. Live streaming a lecture with […]

Live Audio and Video over WebRTC’s datachannel

UNINETT IoU has over the summer developed a WebRTC demonstrator which attempts something “naughty”… As part of our work on WebRTC as well as our work within low latency collaboration tools, we decided to find an answer to the following research questions: Is it possible to transfer live audio and video over the data-channel in […]

Clean Sky and Netsys 2017

Research and Study Network Technologies – White Paper

Uninett contributed to the white paper, which have been published in conjunction with GEANT4 deliverable D13.1. This deliverable reports on the work carried out by GN4-1 Joint Research Activity 1 Future Network Topologies, Task 1 Current and Future Network Technologies to investigate the trends and technologies in optical transport networks and how these can be […]

Alien wavelength 100G field interoperability testing

We performed 100G field alien wavelength test over 1235km of DWDM-path. The purpose of the test was to verify support of 100G alien wavelengths in UNINETT’s (Norway’s NREN) optical network. In addition, UNINETT wanted to gain some experience with new 100G OTN/DWDM cards from Juniper and Cisco, and prove the interoperability between them. The following […]

NTP Clock Synch Accuracy – It’s time for microseconds

Making accurate clock signals available has been an ongoing challenge for mankind for millenniums (ref wikipedia).   We have increased accuracy gradually, from half hours (sundials) down to nanosecond (atomic clocks) over all those years. But an accurate clock is worth little if it is not synchronized with other clocks relevant in a certain setting, […]

In search for “the meaning of SDN”

UNINETTs 2015 innovation project on SDN technology has continued the search for a “the meaning of SDN” for an IP backbone network operator. A growing number of vendors and  communities (both commercially driven and more idealistic)  keep on announcing enthusiastically SDN as the way to go while also posting warnings about believing SDN is the […]

High Quality Multimedia Tools for Sophisticated Users

During 2015 the Multimedia Infrastructure innovation project (MMI2015) has continued UNINETT’s work towards a future infrastructure capable of satisfying high requirements to multimedia content and transport quality. I MMI 2015 a fair amount of time has been spent collaborating with test-users from the domain of music and musical theaters. Department of Music at NTNU and […]
