mesh组网跟有线直连哪个好
作者:我是四海飘零
前言
今年下半年就已经开始实施将家里的网络彻底改造一番了。5月底在淘宝入手了猫棒和光纤收发器也用上了有4个多月的时间啦。
收到猫棒的第一时间就将光猫给替换掉了,那是为了让弱电箱的空间更充裕。 原先计划打算加台2.5G的交换机,后面想了一下换思路了。决定把家里预埋的同轴电缆给抽了,直接替换成超五类网线。
这个是当年我们家的网络结构情况,弱电箱有一根网线到客厅的墙插,另外的三个房间的墙插都是汇聚到弱电箱的,我原本计划是准备入手5口2.5G交换机的。但是对于用无线路由器进行Mesh组网来说有线Mesh最佳的方式是主路由器下接一个副节点的路由,也就是主路由器(LAN口)下挂一个副节点路由器(WAN口)。我是想客厅放一台无线路由器,其他房间的墙插网口都汇聚到客厅来,方便我后期添加无线路由器做有线Mesh组网。
现在方案是弱电箱里只放光纤收发器+猫棒(桥接),通过超五类直接到客厅网口墙插上。再将客厅和剩余房间的同轴电缆也抽出来替换成超五类网线。放弃原先预埋网线到弱电箱的网络结构。将每个房间的同轴电缆汇聚到客厅的同轴电缆全部替换成超五类网线,这样重新布线可以将超五类网线汇聚到客厅墙插的网口面板上。
现在家里的同轴电缆都给替换成了超五类网线,这是拆下了客厅的同轴电缆和同轴86盒子面板。可以看到同轴电缆的线还是很粗的,同尺寸的同轴电缆在线管里可以换成两根超五类网线。
客厅的同轴线的86盒面板换成这种双网口的86盒网口面板就行了。因为线管是可以穿两条网线的,如果是单网口会占用一个86线盒,换成双网口的86盒网口面板就会整洁美观多了。
TP-LINK的TL-XDR6088无线路由器,当时买了3台做有线Mesh组网。也是6月初买的,结构那个时候Docker还未推送固件更新没发体验,再就是3台6088路由组网后存在断网的情况。具体情况就是,6088的副路由会断网,组网后依旧存在网络断流的情况。用了四五实在是受不了,就申请了七天无理由退货。
TP的6088路由器的体积还是蛮大的,摆放在电视柜也很占位置。
当初选择的理由有两点:1、说是支持Docker(我买的时候固件并不支持,当时属于画饼的状态)。2、双2.5GbE网口。现在看起来我手里都有NAS了,为啥还要用无线路由器玩Docker?如果不是网络断流的问题影响使用体验,我也许当时就不考虑退货了。
购买
最后研究了一番,想着说用Mesh组网挑选无线路由器,要知道目前无线路由器清一色的高通、博通、联发科处理器,选自研处理器的无线路由器也就只剩下中兴和华为了。华为的HiLink智联并不是Mesh组网体验,所以我就只考虑中兴了。最后还是决定在京东上入手3台ZTE AX5400 Pro来用用。
路由器系统的网络拓扑图
三台AX5400 Pro组网体验,其中ETH是网线直连做有线Mesh组网,5G频段直连做无线Mesh组网。
开箱就不做了,反正站内一大堆开箱。不过说实在的中兴AX5400 Pro的重量明显要比TP-LINK XDR6088要重很多。
看过ACWIFI站长对中兴AX5400 Pro的拆机,理论上是还可以有多一个2.5G网口的空焊位,期待以后中兴出双2.5G网口的无线路由器。
在次卧布置的第二台无线路由器(副节点)。
这个是主卧摆放的第三台无线路由器,做得无线Mesh组网。
有线Mesh组网,是桥接模式,回传:ETH。
无线Mesh组网,是无线链路模式,回传:5G。
绿联DH2600(2.5GbE)网口体验
Intel N5105四核处理器,4GB DDR4 2666内存条(有2个独立SO-DIMM内存插槽,实测单条16GGB内存条完全没问题)双3.5硬盘仓位和双M.2 NVMe SSD插槽位(四个插满最高可扩展40TB存储空间),1个2.5GbE网口。
绿联DH2600是绿联首款带2.5G网口的NAS产品,可以部署Docker玩玩容器化,带有两个USB 3.0和Type-C接口,NAS扩展性不错。一开始是为了给我老婆的传媒工作室买的,后来发现工作室实际使用NAS的程度不高,我就拿回家用了,把之前闲鱼收的铁威马扔工作室去了。
绿联DH2600 NAS的有线网络已经是2.5G网络接入,这里网络状态显示:2500Mbps,全双工,MTU1500。
在绿联云的Mac APP上也能查看到网络状况:2500Mb/s,全双工,MTU1500。
MacBook Pro上通过使用优越者Type-C转RJ45 2.5G网口扩展坞来解决没有网口的缺憾,这也是少有网口带指示灯的扩展坞。
默认只要是2.5G网络接入,速度:2500Base-T,全双工,MTU1500。
通过Mac的终端查询,当前网络连接状态:2500Base-T
其实macOS自带了网络测速命令,输入后进行网速测试,上传:21.150 Mbps,下载:872.413 Mbps。
找了台Windows轻薄笔记本电脑,用的是优越者的Type-C转千兆2.5G网卡。
可以看到2.5G网卡的链接速度:2500 Mbps。
在绿联DH2600 NAS上自建LibreSpeed测速平台,用Windows轻薄本上测速,下载:2071 Mbps,上传:2507 Mbps。
在绿联DH2600 NAS上自建HomeBox测速平台,用Windows轻薄本上测速,下载:1.83 Gbps,上传:2.19 G bps。
在绿联DH2600 NAS上传9.66GB的VHDX文件,在2.5G网口下的上传速度:272.0 M/s。
在绿联DH2600 NAS下载9.66GB的VHDX文件,在2.5G网口下的下载速度:248.9 M/s。
绿联DH2600 M.2 NVMe SSD的存储测速(2.5GbE)
用Disk Speed Test For Mac测得1GB数据,连续写入:254.0 MB/s,连续读取:245.3 MB/s。
用AJA System Test Lite测得1GB数据,连续写入:231 MB/s,连续读取:233 MB/s。
用AmorphousDiskMark 3.1测得1GB数据,连续读取:269.69 MB/s,连续写入:177.11 MB/s。
用ATTO DISK BENCHMARK测得1GB数据,连续读取:266.50 MB/s,连续写入:283.37 MB/s。
绿联DH2600 SATA SSD的存储测速(2.5GbE)
用Disk Speed Test For Mac测得1GB数据,连续写入:189.5 MB/s,连续读取:204.4 MB/s。
用AJA System Test Lite测得1GB数据,连续写入:229 MB/s,连续读取:188 MB/s。
用AmorphousDiskMark 3.1测得1GB数据,连续读取:207.60 MB/s,连续写入:112.26 MB/s。
用ATTO DISK BENCHMARK测得1GB数据,连续读取:216.91 MB/s,连续写入:283.44 MB/s。
无线信号覆盖测试
三台无线路由器摆放的位置。分别是:客厅、次卧(卧室C),主卧(卧室B)。其中次卧到客厅是有线Mesh组网,主卧窗台那是无线Mesh组网。
NAS自建内网测速,iPhone 13在客厅和次卧(卧室C)的无线测速。
NAS自建内网测速,iPhone 13在厨房和客房(卧室A)的无线测速。
NAS自建内网测速,iPhone 13在卫生间B和主卧(卧室B)、阳台的无线测速。
总结
自从买了三台中兴AX5400 Pro做了有线Mesh和无线Mesh的组网后,访问家里绿联DH2600 NAS的影音体验变好了,局域网内的上传和下载速度也变快了,能彻底用上2.5G局域网的体验还是蛮不错的。希望中兴能够推出带双2.5G网口的无线路由器,要是能在无线路由器上有个SFP插槽就更好了。反正很多人家里弱电箱都比较小,也期待什么时候国内能普及带四个口的2.5G网口光猫,这样就可以省去再购买一台2.5G交换机的钱。
