减慢游戏运行速度
You pay good money for your speedy broadband connection, and it would be a shame if a poor hardware choice was hampering your network. Are network switches to blame for your slow connection?
您为快速的宽带连接支付了很多钱，如果硬件选择不当妨碍了您的网络，那将是可耻的。 网络交换机是否应归咎于您的缓慢连接？
We get a not-insignificant number of reader inquiries about network hardware, especially concerns over whether or not a network switch is to blame for home network problems—primarily issues with connection speed and stability. Despite the suspicion that so many people seem intent on casting towards the poor network switch, it’s very rarely the source of network problems.
读者对网络硬件的询问数量可观，尤其是对于家庭网络问题(主要是连接速度和稳定性问题)是否应该归咎于网络交换机的担忧。 尽管怀疑有太多人似乎打算投向不良的网络交换机，但这很少是网络问题的根源。
Like all statements regarding technology, however, there’s always and exception or two. Let’s take a moment to rule out any of the problems you might have with a network switch that could actually impact your network speed.
像所有有关技术的陈述一样，总是有例外或一两个例外。 让我们花点时间排除网络交换机可能会实际影响网络速度的任何问题。
您的交换机实际上是集线器 (Your Switch Is Actually a Hub)
Hands down, with very few exceptions, when we’re helping someone troubleshoot performance performance problems after installing a switch, the switch is….well, not a switch at all.
毫无疑问，当我们在安装交换机后帮助某人解决性能性能问题时，该交换机就是……。

You can read more about the difference between switches and hubs here, but here’s the gist. A hub and a switch look physically similar: they have X number of ports (typically in multiples of 4 like 4, 8, 16, 24, and so on) with one reserved for use as an input or a totally separate port labeled “uplink”. Despite their nearly identical appearance, however, the guts of the two pieces of network hardware are quite different.
您可以在此处了解有关交换机和集线器之间差异的更多信息 ，但这是要点。 集线器和交换机在物理上看起来相似：它们具有X个端口(通常是4的倍数，例如4、8、16、24等)，其中一个保留用作输入，或者一个完全独立的端口标记为“上行链路” ”。 尽管它们的外观几乎相同，但是这两个网络硬件的内在却截然不同。
A hub is a “dumb” device in that it broadcasts whatever it hears on the input port to all the output ports. This leads to collisions between data packets and a general degrading of network quality. If you have a hub set up between your router and the rest of your network, you’re setting yourself up for a huge headache.
集线器是一种“哑巴”设备，它会将在输入端口上听到的内容广播到所有输出端口。 这导致数据包之间的冲突以及网络质量的普遍下降。 如果您在路由器和网络的其余部分之间建立了一个集线器，那么您将很头疼。
A switch, on the other hand, is much smarter. It actively manages the connections between the input port and the output ports, so you won’t run into the collision problem or any of the other issues that plague hubs.
另一方面，开关要聪明得多。 它主动管理输入端口和输出端口之间的连接，因此您不会遇到碰撞问题或困扰集线器的任何其他问题。
If you purchased the device in question within the last few years, the chance is almost zero that it’s a hub. Historically, switches were expensive and hubs were cheap, but advances in technology have made switches so cheap that they don’t even bother making hubs anymore. If you fished your “switch” out of an old box in the corner of your basement or bought it dirt cheap at a surplus sale, look up the model number online and confirm that its not a hub.
如果您在最近几年内购买了有问题的设备，那么它是集线器的机会几乎为零。 从历史上看，交换机很昂贵，而集线器很便宜，但是技术的进步使交换机变得如此便宜，以至于它们再也不必打扰集线器了。 如果您将“开关”从地下室一角的旧盒子中捞出或以多余的价格廉价购买，请在网上查找型号，并确认其不是集线器。
您的交换机很旧，但连接没有 (Your Switch Is Old, But Your Connection Isn’t)
Ethernet connection speeds are dependent on the quality of the cabling and the capabilities of the network hardware. Some very old switches are only capable of 10 Mbit/s, switches built from the mid-1990s forward are capable of 100 Mbit/s, and modern switches capable of 1000 Mbit/s (or “gigabit” speeds). The type of cables you use matter too: older Cat5 cabling can’t handle gigabit speeds, but newer Cat5e and Cat6 can. So if your connection is slow, you might have an older, slower piece of hardware somewhere in the chain. Check your switch’s model number and the cables you’re using (the type, Cat5/5e/6 will be printed right on the cable sheathing).
以太网连接速度取决于电缆的质量和网络硬件的功能。 一些非常老旧的交换机只能提供10 Mbit / s的速度，从1990年代中期开始构建的交换机可以提供100 Mbit / s的速度，而现代交换机则可以提供1000 Mbit / s(或“千兆”速度)的能力。 您使用的电缆类型也很重要：较旧的Cat5电缆无法处理千兆位速度，而较新的Cat5e和Cat6则可以。 因此，如果连接速度较慢，则可能是链中某处的硬件较旧，速度较慢。 检查交换机的型号和使用的电缆(类型Cat5 / 5e / 6将直接印在电缆护套上)。
While 100 Mbit/s, despite being an older standard, is still plenty fast for most broadband connections, if your broadband connection is a screaming fast shiny new fiber connection then you don’t want to hinder your throughput with an old switch. If your internet connection is faster than 100 Mbit/s, you’ll want to upgrade your hardware (and potentially cabling) to take full advantage of it.
尽管100 Mbit / s尽管是一个较旧的标准，但对于大多数宽带连接来说仍然足够快，但是如果您的宽带连接是令人发指的快速闪亮的新光纤连接，那么您就不想使用旧交换机来阻碍吞吐量。 如果您的Internet连接速度超过100 Mbit / s，则需要升级硬件(并可能连接电缆)以充分利用它。
您的硬件出现故障 (Your Hardware Is Failing)
Speaking of old hardware, failures happen even with quality equipment. While sometimes hardware fails catastrophically (the power transformer gives up the ghost, a piece on the circuit board pops and releases all the magic smoke, etc.) many times network hardware dies a slow death that isn’t so much as snap, crackle, and pop but a protracted whimper.
说到旧硬件，即使使用优质设备也会发生故障。 虽然有时硬件会发生灾难性的故障(电源变压器会消除鬼影，电路板上的一块东西会突然弹出并释放出所有魔力的烟雾，等等)，但网络硬件多次死于缓慢的死亡，而不仅仅是响亮、,啪声，和流行，但持久的抱怨。

For example, earlier this year I was troubleshooting my internet connection problems, layer-by-hair-pulling-layer, to figure out why my connection speed was 5% of what it should have been. Eventually, I traced the problem back to what seemed like an unlikely source (but that we later learned was actually a common point of failure): the Ethernet pass-through port in our Uninterruptible Power Supply (UPS) unit.
例如，今年早些时候，我正在逐层拉扯我的Internet连接问题，以弄清楚为什么我的连接速度是应该达到的速度的5％。 最终，我将问题追溯到似乎不太可能的原因(但后来我们得知这实际上是一个常见的故障点)：我们不间断电源(UPS)单元中的以太网直通端口。
The port hadn’t failed completely, it had simply degraded in quality to the point where we were experiencing frequent connection loss and a fraction of the throughput we should. The same thing can happen to network switches. So when in doubt, remove the network switch from the equation to see if failing hardware is to blame.
该端口并没有完全失败，它只是质量下降到了我们经常遇到的连接丢失和我们应有的吞吐量的一小部分的程度。 网络交换机可能会发生同样的事情。 因此，如果有疑问，请从公式中删除网络交换机，以查看是否应归咎于出现故障的硬件。
您的网络负担沉重 (Your Network Is Overburdened)
In this last instance, the network switch isn’t at fault as much as it’s an enabler. Why do we use network switches, after all? Because we need to connect more devices, like computers and game consoles, to network.
在最后一种情况下，网络交换机并没有像启动器那样有过错。 毕竟，为什么要使用网络交换机？ 因为我们需要将更多设备(例如计算机和游戏机)连接到网络。
More devices and more people using them means our precious bandwidth is split between more people. Suddenly, with everyone and their brother streaming video to their bedrooms, the pipe just isn’t big enough. That’s not the fault of the switch, though: just the devices connected to the switch. If you can’t upgrade to a faster connection, you can always deploy Quality of Service (QoS) at the router level to help manage the demand on your connection.
更多的设备和更多的人使用它们，意味着我们宝贵的带宽被更多的人分配。 突然，每个人和他们的兄弟将视频流传输到他们的卧室，管道还不够大。 但是，这不是交换机的问题：仅仅是连接到交换机的设备。 如果无法升级到更快的连接，则始终可以在路由器级别部署服务质量(QoS)，以帮助管理对连接的需求。
In short: if it’s not a hub, isn’t old or on fire, and your hardware and cabling are up to date, there’s very little chance that the humble network switch is the source of your connection woes.
简而言之：如果它不是集线器，不是旧的或着火的，并且您的硬件和电缆是最新的，则不起眼的网络交换机是造成连接故障的根源的可能性很小。
