We are to one of Telia’s major exchanges, discreetly positioned behind a massive steel door in a building in central Uppsala. The exact address is confidential and absolutely nothing on the outside gossip about telecommunications station’s existence.
class=”paragraphIntro”> This is a of eleven major exchanges in the country, despite fixed telephony cases, with flower reopened. But now that the advanced video server centers for Telia’s TV service.
class=”paragraphIntro”> today necessary switching centers also to meet the exploding amount of streaming video-on-demand television in Telia’s network. Every second, started two new on-demand applications in TV service program library and a quarter of a million movies rented monthly.
class=”paragraphIntro”> It is not enough longer to just escape the soaring data volumes of frequently HD-resolution video from a single central video server. Medicine is pushing out the most popular on-demand content to the video servers in central offices further out in the network, closer to the viewers.
class=”paragraphIntro”> – We make like this in order not to risk all on demand videos are overloading the central parts of the core network. The more TV customers who watch on demand, the greater the need for such solutions. There is nothing strange really. We streamline network usage by caching the most popular video content closer to the user, says Leif Bengtsson, Director of Engineering for Telia’s TV service.
class=”paragraphIntro”> technician Thomas Zellman opens the heavy steel door and we walk into the telecommunications station’s bowels.
class=”paragraphIntro”> entire ongoing technology shift where an increasing number of throws out the land line while telecom giant TV services is growing fast , has been emulated inside the exchange.
class=”paragraphIntro”> First we pass large halls that make up the heart of the Uppsala region’s fixed telephony. Large amounts of copper wires coiled into huge gear system. But a significant portion of the floor space in these halls gaping empty.
class=”paragraphIntro”> Then we come to another hall that make up the Center for Telia fiber and television services. There are no dead spots. Every square is packed with switches, servers and other hardware with pleasantly humming cooling system.
Television has grown rapidly in Telia’s network. The number of customers has basically doubled in the past five years, and today 620 000 Telia customers TV service. Still looking closely häflten by customers on television via ADSL broadband ordinary copper wires.
class=”paragraphIntro”> In TV service available both regular broadcastade TV channels and television programs and rented movies on demand. But it’s on-demand content that increases the absolute most of the network.
class=”paragraphIntro”> – It’s a quick search, while we have in the last year seen a flick down the curve of linear television, says Johanna Berlinde, Business Manager for TV and entertainment at Telia.
class=”paragraphIntro”> entire supply chain for Telia’s TV content based on two mirrored main sites in Stockholm with hundreds of terabytes of video content. When someone starts an application on demand for the first time, loaded the video file at the same time over to a local video server in the switching center that is closest to the viewer. When another television viewers in the same region to see the same on-demand application is launched directly from the local video server, without burdening television service principal sites in Stockholm.
class=”paragraphIntro”> – It is only the most popular programs, perhaps a hundredth of total on-demand content, which is stored in one of the eleven local video servers. Enough, says Leif Bengtsson.
class=”paragraphIntro”> Overall, the eleven local video buffet engines in Telecom exchanges capacity to stream around 50-60 Gbit / s of video of a load network around the central video servers in Stockholm thereby avoid.
class=”paragraphIntro”> Today nothing pointing to an end to the increase of on-demand video in Telia’s TV service. But in the current situation there are no plans to take further steps and move video content closer to the users. For example, the control cabinets for fixed telephony and broadband that’s even further out into telecommunications networks ramifications.
class=”paragraphIntro”> – No, in If so, is it more reasonable to establish additional local video servers in more exchanges. But of course, it is both theoretically and practically possible to also move video content closer to the users, says Leif Bengtsson.
