泰坦陨落Xbox LIVE云计算解析

The vast majority of games will pick a player and have them act as the server for the match. This means that all of the other players talk to them to decide what happens in a game. When you shoot your gun, the server decides if that is allowed and then tells everyone what you hit. Let’s agree to call this system “player-hosted” for simplicity.What kinds of problems do you get with player-hosted servers?

玩家作为服务器大量的游戏会采用选择一个玩家，然后那个玩家将承担服务器的角色。这意味着这场游戏里的所有玩家都会和选定的玩家进行通讯来决定游戏将会发生什么。当你开枪，服务器（选定玩家的主机）来决定那是否是允许的，然后告诉每个玩家你打到了什么。让我们把这种方式称为“玩家做主机”来使描述更加简单。当你用这种方式时到底有什么问题呢？

What if one player has great bandwidth, but it’s laggy? Games are having to choose between different player hosts, and have to make hard decisions about which one should be the host, with two different measurements – bandwidth and latency. Sometimes it will pick a host who has good bandwidth, but whose latency isn’t ideal. But we don’t want the game to make compromises on lag and we really want the game to feel the same every time we play. We really don’t want to worry about this stuff – we just want to play and have the game feel good.

如果一个玩家有很高的带宽，但是延迟很高会怎么样呢？
