由哪个工业路由器负责与核心系统进行可达信息通信?   应该由哪个工业路由器负责与核心系统进行可达信息的通信呢?这个难题是来自于我们仅仅考虑了互连网络选路体系结构而没有考虑管理机构的作用。在全网工业级路由器主干网的网点可以具有复杂的本地结构的情况下,由于网络和工业级路由器都在单独的管理机构控制之下,这个机构就要负责保证其内部的工业无线路由器路由信息的一致性和可用性。另外,管理机构还要选择其内部的一台机器负责向外界提供网络的可达信息。由于工业级4G路由器R2、R3和R4处于同一管理机构的控制之下,管理机构指定R3来通告网络2、3、4的可达信息(我们认为核心系统早就知道网络1的情况,因为有一个核心工业路由器直接与之相连)。4g路由器   从选路的角度来说,处于一个管理机构控制之下的网络和工业级无线路由器群组称为一个自治系统。在一个自治系统内的路由器可以自由地选择寻找路由、广播路由、确认路由以及检测路由的一致性的机制。在这样的定义下,核心工业级路由器自己也构成一个自治系统。我们说过原先的Internet网的核心路由器使用GGP来进行通信,而后来改为使用SPREAD。这个改变并不影响其他的全网通工业路由器自治系统。   为了能通过Internet到达隐藏在自治系统中的网络,每个自治系统必须把自己工业级全网通路由器的网络可达信息传播给其他自治。虽然在核心体系结构中可以把全网通工业路由器路由通告送给任一个自治系统,但是每个自治系统有必要把自己的信息传送给某个核心工业路由器。有可能存在若干工业级无线路由器,每个负责通知一个网络子集合。   我们对自治系统的定义可能有点含糊不清,但是在实践中自治系统之间的划分必须区分严格,以便于使用自动选路算法。例如,一个自治系统属于某个公司,它可能不会选择这样的工业级4G路由器路由,把工业4G路由器分组转发到与之直接相连的但属于另一个公司的某个自治系统。为了让自动选路算法能区分各个自治系统,各自治系统被赋予一个自治系统编号(autonomous...

路由转发协议和选择协议是相互配合又相互独立的概念   当IP子网中的一台主机发送IP分组给同一IP子网的另一台主机时,它将直接把IP分组送到网络上,对方就能收到。而要送给不同IP于网上的主机时,它要选择一个能到达目的子网上的路由器,把IP分组送给该工业路由器,由路由器负责把IP分组送到目的地。如果没有找到这样的工业路由器,主机就把IP分组送给一个称为“缺省网关(default...

工业路由器防火墙的局限性和什么是物理隔离   防火墙的局限性。4g路由器   (1)防火墙只能防范经过全网通工业级路由器防火墙的攻击。没有经过全网通工业路由器防火墙的数据,防火墙不能检查。   (2)防火墙防外不防内。   (3)防火墙由于在配置和管理上比较复杂,所以容易造成全网工业路由器安全漏洞。   (4)防火墙无法防范病毒,抵御数据驱动式的攻击。   (5)防火墙不能防止利用标准网络协议中的缺陷以及服务器系统的漏洞进行的攻击。   (6)防火墙不能防止全网工业级路由器本身的安全漏洞的威胁。   4g无线路由器:什么是物理隔离。中国电子政务网之间与外网之间是什么关系。全网路由器物理隔离是指内外网络在物理上是完全独立、断开的,没有任何物理连接,但在逻辑上则保持连接,能够进行适度的数据交换。关系:电子政务内网和电子政务外网之间是物理隔离,电子政务外网与公网之间是逻辑隔离。物理隔离的原理1正常情况下,全网通路由器隔离设备和外网、隔离设备和内网、外网和内网之间是完全断开的。隔离设备可以理解为纯粹的存储介质和一个单纯的物理隔离控制设备。2当外网需要有数据到达内网的时候,以电子邮件为例,外部的服务器立即发起对工业4G路由器隔离设备的非TCP/IP的数据连接,隔离设备将所有的协议剥离,将原始的数据写入存储介质。根据不同的应用,可能有必要对数据进行完整性和安全性检查,如防病毒和恶意代码等。3一旦数据完全写入隔离设备的存储设备,隔离控制设备立即中断与外网的连接。转而发起对工业级4G路由器内网的非TCP的数据连接。隔离设备将存储设备内的数据推向内网。内网收到数据后,立即进行TCP/IP的封装和应用协议的封装,并交给应用系统。在工业路由器隔离控制设备收到数据传输结束的消息后,隔离设备立即切断隔离设备与内网的直接连接。这时整个网络又重新恢复到完全隔离状态。4如果这时内网有电子邮件要发出,隔离控制设备收到内网建立过接的请求后,建立与工业级路由器内网之间的非TCP/IP的数据连接。隔离设备剥离所有的TCP/IP和应用协议,得到原始的数据,将数据写入隔离设备的存储介质。如果有必要,就对其进行防病毒处理和防恶意代码检查,然后中断与双卡路由器内网的直接连接。   标签:无线路由器  ...

SIMATICNET工业以太网具有哪些特点?   在任何一个自动化系统中,通讯都是非常重要的一个环节。在制造自动化和过程控制中,必须要保证通讯的无故障化。工业路由器网络或通讯中的故障可能导致整个系统的瘫痪。系统中断必然会引起很高的成本开销。因此,要尽量避免通讯和网络故障。4g路由器   SIMATICNET工业以太网具有下列特点,可以满足上述要求:   •满足EN50082-2标准中所要求的对干扰的免疫性   •可以对工业级路由器网络中的元件提供24VDC冗余   •可以检测信号错误   •可为低水平工业进行扩展   •满足EMC条件   •冗余网络结构   冗余网络结构可保证网络底层的工作稳定性,即使网络发生了错误。在自动化,尤其是过程控制中,更要求工业4G路由器系统有较高的适应性,通过使用高端的终端设备可以达到此要求。4g路由器   环形冗余   仅仅通过使用附加的电缆,就可以将工业级4G路由器网络构建成环型,从而获得效率高且经济的冗余网络。如果网络主动元件实效或电缆断路时,网络只需花费几毫秒的时间进行自主配置。因此,可以避免在昂贵的生产线中发生工业4G无线路由器网络故障。SIMATICNET环型冗余网络可以用光纤和双绞线构建,传输速率可达工业以太网标准。   信号传输原理   信号传输原理实现了一种简单且非常经济的手段对网络进行监视。尤其是对冗余网络非常有效。由于介质冗余,工业级4G无线路由器通讯连续性和传输路径这些错误很难被发现,会导致在后续的通讯中出现网络完全瘫痪。如果使用DIN星型连接器OLM,所有的主动4G工业路由器工业以太网网络元件共同形成了为信号接触器。通过4G路由器网络元件的共同配合,提供了24VDC可以对各元件或网络做出不同状态的信号指示。这些指示也可以3G无线路由器连接至HMI系统(比如WinCC)。这样,在故障发生后,所有的错误都可以被及时的修复。除了信号接触器外,网络元件也可以安装LEDs,以显示不同的状态。   网络管理   在很多情况下,都是通过信号接触器来对FDD-LTE路由器网络进行监视。但并不是所有场合都适合用信号接触器来监控网络,尤其是大型,多分支网络以及无法读取数字信号的终端设备。   因此,SIMATICNET带有网络管理功能,通过新型的OSM/ESM(光电转换模块/电气转换模块)可以对网络TDD-LTE路由器进行管理,监测和诊断。   标签:4g无线路由器   ...

  •          Vehicle logistics and diagnostics controlling
  •          Parking meter and Taxi Monitor
  •          Telecom equipment supervision (Mobile base station, microwave or optical relay station)

The NEW H685 openwrt router adopted the latest developed firmware, which is much more powerful than before. The most  remarkable feature is OpenVPN, this means a lot.

OpenVPN’s use of common network protocols (TCP and UDP) makes it a desirable alternative to IPsec in situations where an ISP may block specific VPN protocols in order to force users to subscribe to a higher-priced, “business grade,” service tier。

 

When OpenVPN uses Transmission Control Protocol (TCP) transports to establish a tunnel, performance will be acceptable only as long as there is sufficient excess bandwidth on the un-tunneled network link to guarantee that the tunneled TCP timers do not expire. If this becomes untrue, performance falls off dramatically. This is known as the “TCP meltdown problem”

Besides, H685 added 700Mhz(B28) in its range this time, especially for Australia users.

TDD LTE and FDD LTE

文章目录 : 技术相关

As we know, the LTE mainly covers two types, which are TDD and FDD.  Let’s talk something about TDD LTE and FDD LTE’s Advantages / disadvantages of for cellular communications.

There are a number of the advantages and disadvantages of TDD and FDD that are of particular interest to mobile or cellular telecommunications operators. These are naturally reflected into LTE.

COMPARISON OF TDD LTE AND FDD LTE DUPLEX FORMATS
PARAMETER TDD LTE FDD LTE
Channel reciprocity Channel propagation is the same in both directions which enables transmit and receive to use on set of parameters Channel characteristics different in both directions as a result of the use of different frequencies
Paired spectrum Does not require paired spectrum as both transmit and receive occur on the same channel Requires paired spectrum with sufficient frequency separation to allow simultaneous transmission and reception
Hardware cost Lower cost as no diplexer is needed to isolate the transmitter and receiver. As cost of the UEs is of major importance because of the vast numbers that are produced, this is a key aspect. Diplexer is needed and cost is higher.
UL / DL asymmetry It is possible to dynamically change the UL and DL capacity ratio to match demand UL / DL capacity determined by frequency allocation set out by the regulatory authorities. It is therefore not possible to make dynamic changes to match capacity. Regulatory changes would normally be required and capacity is normally allocated so that it is the same in either direction.
Guard period / guard band Guard period required to ensure uplink and downlink transmissions do not clash. Large guard period will limit capacity. Larger guard period normally required if distances are increased to accommodate larger propagation times. Guard band required to provide sufficient isolation between uplink and downlink. Large guard band does not impact capacity.
Cross slot interference Base stations need to be synchronised with respect to the uplink and downlink transmission times. If neighbouring base stations use different uplink and downlink assignments and share the same channel, then interference may occur between cells. Not applicable
Discontinuous transmission Discontinuous transmission is required to allow both uplink and downlink transmissions. This can degrade the performance of the RF power amplifier in the transmitter. Continuous transmission is required.

路由器不能上网怎么解决
随着电脑和网络的普及,在家上网已经成为司空见惯的事了,有的家庭可能家中不只一台电脑,这时候为了保证家里各个成员都可以上网有一台路由器就是必备的了。但是有的朋友经常因为配置有误而造成路由器产生故障,那么今天就让编辑给你支支招帮您轻松搞定这些问题。
无法浏览网页
故障现象:网页以不能正常打开,但是QQ之类的程序却可以正常运行。
解决方法:要解决这个问题,建议在路由器和计算机网卡上手动设置DNS服务器地址((ISP局端提供的地址),打开路由器设置界面,找到“网络参数”中的“WAN口参数”的字段,然后在下面手动设置DNS服务器地址。另外,在“DHCP服务”设置项,也需要手动设置DNS服务器和备用的DNS服务器地址,该地址需要从ISP供应商那里获取。
无法进行拨号
故障现象:不能进行正常的拨号程序。
解决方法:这种问题的解决方法比较简单,具体做法是:打开Web浏览器,在地址栏中输入路由器的管理地址,如192.168.1.1,此时系统会要求输入登录密码(该密码可以在产品的说明书上查询到),登陆后进入管理界面,选择菜单“网络参数”下的“WAN口设置选项,在右边主窗口中,“WAN口连接类型”选择“PPPoE”,输入“上网账号”及“上网口令”,点击连接按钮即可。
部分计算机无法正常连接
故障现象:路由器硬件上没有问题,所连接的计算机也没有问题,但是却不能实现正常连接,而局域网中的其他计算机可以正常连接上网。
解决方法:先将被绑定MAC地址的计算机连接至路由器LAN端口(但路由器不要连接Modem或ISP提供的接线),然后,采用路由器的MAC地址克隆功能,将该网卡的MAC地址复制到宽带路由器的WAN端口,接着在未被绑定的计算机上进行如下操作:Windows 2000/XP下按“开始→运行”,输入“cmd/k ipconfig /all”,其中“Physical Address”就是本机MAC地址。

串联两个路由器如何上网
在我们上网的时候通常会发现这样的一种情况,在一根网线已经链接到了一个路由器的接口之后,我们姑且将它称之为路由器A,在路由器A再分出一根线还要链接另外一个路由器,我们称之为路由器B,那么问题是这个路由器…
在我们上网的时候通常会发现这样的一种情况,在一根网线已经链接到了一个路由器的接口之后,我们姑且将它称之为路由器A,在路由器A再分出一根线还要链接另外一个路由器,我们称之为路由器B,那么问题是这个路由器B该怎样实现正常的上网功能呢?
今天我们来谈一下利用两台路由器,网线和电脑这三者的链接方式和设置办法,从而实现最终的双重上网功能。具体的步骤是:首先需要查看一下两款路由器的IP地址是否一致,如果不相同的话那么可以跳过这步,实际上一般的路由器的IP是192.168.0.1。接着进入路由器B的管理界面,找到路由器B的LAN接口,并将路由器B的IP地址设置为192.168.1.1,然后保存。那么以后路由器B的IP就变成了重新设置好的这个地址了。
接着,让让路由器A连接到网络并进入路由器A的管理界面,同时将DNS和子网掩码等信息复制,并在界面上显示出来。然后,将路由器A的LAN口分出来的网线连接到路由器B的WAN接口上,最后在浏览器中输入设置之后的IP地址再进入路由器B。在路由器B中找到其WAN接口,将之设置为静态IP。
将路由器A的 LAN口分出的网线连接到路由器B的WAN口上,再到浏览器中输入修改后的IP地址进入路由器B的管理界面192.168.0.X,这个叉一般表示的是22到254之间任何的参数。其中,子网掩码和DNS的信息与路由器A相同,网关设置为路由器A的管理IP地址,将设置好的IP地址点击保存。
到了此刻,两台路由器就实现了串接,一般当路由器A上网的时候,路由器B连接到电脑之后同样也就可以上网了。

首先打开浏览器,在地址栏输入192.168.1.1之后会弹出对话框,接着输入账号和密码,只要没有设置过,一般的路由器账号和密码都是admin。
再登陆路由器的界面之后出现设置路由器的界面,选择好上网方式,点击下一步,接着继续点击下一步输入必要的上网账户信息再次点击下一步,然后进入无线设置,点击下一步,然后开启DHCP功能(一般是点击系统的右下角的图标)。
最后,右键打开网络中心选择本地连接,回到浏览器选择点击完成就OK咯!

路由器WAN口指示灯不亮是什么原因

文章目录 : 技术相关

路由器WAN口指示灯不亮是什么原因
路由器WAN口灯不亮,检查了路由器的连接,发现线路连接正常。路由器的设置也没有问题,多次试验后路由器WAN口指示灯依旧不亮,出现这种情况该如何解决?
1.首先检查物理线路是否过长,双绞线传输距离一般为100米,如果超过此距离,信号在传输方面会出现衰减比较严重等现象,造成WAN口灯不亮。
2.查看路由器WAN口的端口模式,可能端口模式不匹配。比如网通线路是10M全双工的,而路由器WAN口设置的是100M全双工的,就出现这种情况。尝试修改WAN口速率为10M全双工。
3.检查WAN口是否正常,可以将WAN口连接其他设备或直接连接电脑。如果指示灯正常,能够通讯,则说明WAN口正常。如果指示灯不亮,不能通讯则说明WAN口有问题。
4.检查网线是否正常,可以换根网线或将网线插在其他设备上,看是否正常。
以上就是路由器WAN口指示灯不亮的原因分析及其解决方法,路由器运作不正常时也需要查看指示灯工作状态。
