League Of Legends Is Building Its Own Network To Kill Lag [Update]

Like any other game on Earth, League of Legends suffers from lag. Being the biggest game on the planet, though, means LoL can actually do something about it, and is launching an ambitious plan to build its own network.

UPDATE - Riot tells Kotaku that, while this announcement concerned the US specifically, "we are currently working with ISPs and developing the same internet backbone throughout Europe".

Here's Riot's explanation of how it's going to work:

Currently, ISPs focus primarily on moving large volumes of data in seconds or minutes, which is good for buffered applications like YouTube or Netflix but not so good for real-time games, which need to move very small amounts of data in milliseconds. On top of that, your internet connection might bounce all over the country instead of running directly to where it needs to go, which can impact your network quality and ping whether the game server is across the country or right down the street.

This is why we're in the process of creating our own direct network for League traffic and working with ISPs across the US and Canada to connect players to this network.


The network will be up and running in March. You can read more about it over at Riot.

This is crazy. This is the kind of thing an internet-destroying company like Netflix has to work out. For a single video game to be doing the same thing says a lot about both how popular LoL is, but also how much money it must be making (or plans to make over the coming years).

For a more technical explanation of what's being worked on, here's more from a Q&A on the rollout:

Many players should see improvements in network quality as our new North American network rolls out. These improvements could be less ping time, less network packet loss, and more stable connections (less disconnects). Ping, packet loss, and stability may not all move in the same direction for all players depending on location within North America, their ISP (how their ISP connects to Riot's network).

Ping, packet loss, and stability are not always tied together and can be affected by many things. When it comes to network quality we prioritize stability, reduced packet loss, and ping time pretty much in this order. You can't play the game if you are not connected, you will see more lag with more packet loss, and ping can become a problem when it gets significantly high or is unstable (shooting up and down all the time in the middle of the game).

The game client only reports ping time to players but it also tracks stability and packet loss to Riot (and in client log files) on a near real time basis (though it can take us a day to crunch all the data from all the game clients before we see a troubling trend developing so we are not yet at real time detection of some network problems). Sometimes packet loss will show up in your ping time, usually you will see it jump up and down quickly which often indicates packet loss is happening or if severe packet loss will show up as lag in the game.

Faster ping time is often reported by players to "feel" better and is often something that is reported to be more meaningful the better you are at playing a game. How fast ping is before you feel the difference is likely dependent on the individual but it is generally thought the lower the better (diminishing returns apply, going from 160 ping to 90 ping is more impactful than going from 110 ping to 40). Lower ping time can also help mitigate packet loss since the game can recover missing packets faster. Because the Internet is a loose collection of various private and public networks, ping time is something that will constantly change for players. Some players could see slight increases in ping times while others can see significant reductions as our new network comes online. Our goal is benefit the most players and then troubleshoot ISPs that still have players with poor network quality.

They must be pretty confident in the roadmap that they have in place for LoL in the coming years to want to invest in something like this.

Sure, it's a massive game and makes massive cash, but in around 2-3 years? Dunno, maybe it's still there maybe it isn't. Right now though, they're certainly looking good.
