When the music service Spotify debuted in 2008 it made use of peer-to-peer (P2P) technology to deliver songs and since then it has been technological workhorse for millions of subscribers; however, the company will soon be phasing out that model for centralized servers.

Spotify uses a rolling window of 28 days because the number of days in a calendar month can vary, and because people listen to music differently depending on the day of the week. This means an equal number of days of the week are included—so, the same number of Mondays, Tuesdays, Wednesdays, etc.
According to a TorrentFreak report, the music streaming site Spotify announced the phasing out of its P2P technology in favor of a more traditional architecture of centralized servers.

The Swedish company took the opportunity to mention that switching will make it easier to develop a family service plan where several people from the same household can enjoy their music regardless of what others are listening to.
This move became clear after the company said in a statement that it has increased central server capacity dramatically over the last few months and that in the future it will use this to stream music to users.
P2P technology has served Spotify really well in the company’s fledgling days as the technology has a low cost–as it utilizes customer’s bandwidth and computing to quicken delivery. In fact, Spotify is one of the largest Internet P2P networks. In 2011, 80 percent of the service’s traffic was through P2P networking. When subscribers of the service play a track from the desktop client, the audio stream comes from three sources: a cached file on the computer, one of Spotify’s servers, or from other subscribers through P2P.
But as the company has grown in size and popularity, Spotify feels the technology is no longer enough. Alison Bonny, Communication Director, Europe, said the following about the selection:
“We’re gradually phasing out the use of our desktop P2P technology which has helped our users enjoy their music both speedily and seamlessly,” she said. “We’re now at a stage where we can power music delivery through our growing number of servers and ensure our users continue to receive a best-in-class service.”

Spotify free speaker offer. [ Illustration of how Spotify streams songs from The Pansentient League. ]
Spotify just hit 2.5M paying subscribers and is poised to announce a 'new direction' on Wednesday, four months after launching in the United States. But few people probably give much consideration to how the U.K.-based music streaming service that started in Sweden actually works.
That's why a post on the Spotify-tracking blog The Pansentient League -- based on a 2010 academic paper by Gunnar Kreitz and Fredrik Niemela of Sweden's Royal Institute of Technology and Spotify -- caught our attention. Unlike Pandora and Spotify's competitors, Spotify's desktop app for Windows and Mac uses a peer-to-peer network combined with server-based streaming. Why use P2P? Quite simply, to make the service more scalable and lighten the load on Spotify's servers. Spotify manages to do this without making users wait too long for a requested song to start playing. The paper reports that the median latency of a track is 265 milliseconds, or faster than the average blink of an eye (300 to 400 ms). Any Spotify user can tell you that the speed at which songs play feels instant. Note: Spotify's mobile apps stream only from Spotify's servers [ the paper doesn't address mobile apps.] Among the paper's interesting data points: about 61% of playbacks are listened to in a predictable order (one song after the other in an album, for example) and less than 1% of all playbacks 'stutter.' While just 8.8% of data came from the servers during one measurement period (with 35.8% from the P2P network and 55.4% from cached data), Kreitz and Niemela noticed that more music is played from the cache at night although this is less true on weekend nights, when people play more new music. Also, the P2P network gets more of a workout on weekends than weekdays. In the Hacker News discussion of the Pansentient post, a user who goes by Sudonim says he canceled his Spotify subscription partly because they use P2P networking. 'If I'm paying for it, I don't want to be a node in their network. Most users are probably clueless about that because they aren't up front at all.' The paper points out early on that Spotify uses 'similar mechanisms' for locating peers as file-sharing apps like BitTorrent and Gnutella, services everyone knows are used for illegal downloads. Coupling this with Sudonim's reasoning makes us wonder if Spotify's system might become a PR issue as the company grows. How the P2P Network on Spotify Works When you request a song from Spotify, your desktop app, which is called a 'client' in the Kreitz and Niemela paper, decides where to stream from based on how much data is in your play-out buffer. 'The connection to the server is assumed to be more reliable than peer-connections, so if a client’s buffer levels are low, it requests data from the server,' they write. 'As long as the client’s buffers are sufficiently full and there are peers to stream from, the client only streams from the peer-to-peer network.' When you request music popular with other Spotify users, you're more likely to get the track from the P2P network than the server, Kreitz and Niemela point out. So how is Spotify's P2P network set up? Kreitz and Niemela explain that it's an unstructured network where every peer is equal. Trackers help construct and maintain the network; a tracker keeps a list of 20 of the most recent peers for each song. There are no supernodes performing maintenance functions. Your Spotify client stores local caches of tracks you've downloaded. 'The content of these caches are also what the clients offer to serve to their peers,' write Kreitz and Niemela. The protocol is set up so that your client will only offer tracks it has completely cached. Read section III of the paper if you want the nitty-gritty details of how the trackers find peers and how clients find songs. We like the authors' succinct explanation of how your Spotify client gets connected to the P2P network when you fire it up: 'If it was still listed in the tracker for some tracks then it is possible that other clients will connect to it asking for those tracks. If the user starts streaming a track, it will search the peer-to-peer network and connect to peers who have the track, thus becoming a part of the overlay.' Comments are closed.
