Game Developers Note Net Neutrality Concerns To FCC 74

eldavojohn writes "A list of notes from game developers (PDF) was sent in a letter to the FCC which represented a net neutrality discussion between the developers and FCC representatives. Game Politics sums it up nicely, but the surprise is that developers are concerned with latency, not bandwidth, unlike the members of many other net neutrality discussions. One concern is that each and every game developer will need to negotiate with each and every ISP to ensure their traffic achieves acceptable levels of latency for users. 'Mr. Dyl of Turbine stated that ISPs sometimes block traffic from online gaming providers, for reasons that are not clear, but they do not necessarily continue those blocks if they are contacted. He recalled Turbine having to call ISPs that had detected the high UDP traffic from Turbine, and had apparently decided to block the traffic and wait to see who complained.' It seems a lot of the net neutrality discussions have only worried about one part of the problem — Netflix, YouTube and P2P — while an equally important source of concern went unnoticed: latency in online games."

    The issue isn't specific to ANY type of usage - net neutrality, or rather the lack of it, impacts all uses of the network.
    As long as connectivity providers are also application providers, any application they don't like is a potential candidate for connectivity problems.

    • I'm not sure that net-neutrality would help this. ISPs are blocking high volumes of UDP packets, and they'll claim it's to protect users from DDoS attacks. They may even be telling the truth.

      The summary is also badly composed by following the latency complaint with a quote about blocking traffic. That is, unless you consider a blocked packet to have infinite latency. The letter is much more vague about what their actual latency complaint is, other than, you know, latency is bad.

        I think the summary was fine and that it's obviously a concern about throttling in regards to latency. Games, far more than youtube and other streaming sites, are far more impacted by latency. If the ISP's using throttling, or delaying tactics at the packet level to prioritize traffic, it will have a huge impact on the online gaming experience. What's funny is the effects may be subtle to borderline irritating so that users get a degraded experience that would be easy to blame on the content provider and no

          Throttling does not affect packet latency. At the router level, it generally involves selectively discarding packets. Data is not drip-fed at the bit level or byte level.

          In order to intentionally affect latency, it would have to do a lot more work by buffering them for a period of time before forwarding onwards.

          Now throttling can affect latency of logical messages within a TCP stream depending on the size of those messages, due to the retransmissions required, but does not affect the latency of UDP packets

          • Throttling does not affect packet latency.

            The data has to get there in some form, whether in UDP or TCP packets, so any need to resend does affect session latency. One way to work around packet drops in games is to send absolute positions instead of motion deltas, but that takes more data and affects transmission speed. Latency IS affected.

            Another related issue is any ISP can suddenly decide to privilege their own VoIP service packets in congestion cases, over any other latency or drop sensitive data, like voice chat or other non-ISP VoIP services.

    This really is the opposite end of the bandwidth-latency spectrum from the prominent players in net neutrality. Most MMORPGs will use about 5KB/s downstream and about 1KB/s upstream, even during particularly high activity events. That is not the kind of traffic that net neutrality discussions usually bring up. But even with that small amount of traffic, a player's game experience can be extremely hindered by latency. Different games will have different red lines, but I've found 500ms to be around the point most players will notice a negative affect on gameplay.

    And this is definitely not a PC issue alone. I don't imagine Microsoft would be happy with a major ISP putting Xbox Live traffic at the bottom of the their priorities, or worse, charging customers additional fees to keep their Live latency at a reasonable level.

        I've played with Aussies that had 300 ping, but they walk around smoothly and play decently.

        Then one day I encounted a lagging scout with 25 ping. Every time I got near him to cut off his head, he'd disappear from under my blade. Apparently he was dancing to the side, but when he lags he stops moving until the packets catch up, then teleports to the new location.

    Actually, this is no surprise at all. Maybe most people only focus on the raw speed - i.e., throughput. However, for many applications, the latency - and the lack of sudden latency variations - is more important. These apps are called "inelastic", because they don't tolerate changes in the latency. For example: In a real-time VoIP application, sudden changes in latency make delayed packets useless and the voice gets cut. Yep, you can use a buffer, but that will add an anoying delay in your conversation, so in general the application is highly sensitive to latency changes.

    The same happens with games. If you are playing against sb else, your latency can determine if you live or die. AND, the main problem is that the only solution comes from QoS mechanisms that tag, segregate and priorize different flows of traffic. What, I believe, is somehow against net neutrality.

    I question whether the net should be truly neutral. Favoring Skype and game traffic for short latency wouldn't have much impact on the bandwidth available to streaming content but would certainly improve the quality of gaming and chatting. It seems to me that integrating a packet priority request into the TCP/IP protocol could work. Games and Skype could be given a high priority, browsing medium and torrents low. People who browse and torrent at the same time (or for some reason game and torrent) would have good reason not to override the default priorities. Anyone downloading GBs of data at high priorities by hacking the default settings could be noticed quickly sanctioned appropriately for being a**holes. It would relieve ISPs of excuses for throttling (or at least make the throttling more transparent and remove the need for privacy-invading deep packet inspection).

    The key would be to integrate it into an open standard. I imagine the idea has already been put forth before, but it strikes me that it will be increasing important to have some priority control as the number of latency critical applications as well as streaming content size increases. It would essentially be an open implementation of the "power boost" that some ISPs offer but rely on user-side requests to sort out priorities. Of course, I have no real knowledge of the TCP/IP protocol so I have no idea if it's feasible or even if it's already implemented.

      Besides, ideally, at some point most packets will be encrypted by default. You wouldn't WANT to be able to distinguish types of packets from each other.
      • It won't take long before everybody marks their packets "highest priority".

        Say you have 6 Mbps from the Internet to the home, and your downstream is 20x oversubscribed. Once congestion kicks in, the router starts limiting high-priority packets to 300 kbps so that other users' high-priority packets can get out. Applications that need the high priority, such as games and voice, can easily fit packets into this 300 kbps.

      The hard part is implementing the ability to do that kind of prioritization internet-wide. I'm too lazy to go dig it up, but there was an analysis published a few years back that suggested any possible benefit of building 'smarts' into the network could be achieved simply by increasing the available bandwidth by roughly 30%. And that it was far cheaper to keep the network dumb, as it has been since pretty much the beginning of the internet, and just add capacity than it would be to add all the computative and buffering functionality required to make it smart enough to do prioritization reliably.
