Alpha is a competitive brand in the routing industry. At present, Alpha fiber routers are also launched. Here we mainly introduce the main features of Alpha fiber router R1702. After years of rapid development, Internet cafes across China have formed a large industrial cluster, with a total number of more than 0.1 million. It is precisely because of the optimistic outlook on this market that many people are

Huawei fiber-optic access networks are quite common. So I have studied the New Technology of Huawei fiber-optic access networks. Here I will share it with you and hope it will be useful to you. Optical fiber replacement for copper cables is itself a solution for saving energy and reducing consumption. In addition, all aspects of the network need green design to b

Basic expansion of C language (1) and basic expansion of C Language Tan haoqiang is a beginner in C language. As for this book, it would be good to take the test, but if he wants to engage in programming in the future and deal with C more often, I personally think it is not enough to get started with this book. C primer plus is a better entry-level book with a comprehensive presentation. Therefore, this boo

Ceph Cluster Expansion and Ceph Cluster ExpansionThe previous article describes how to create a cluster with the following structure. This article describes how to expand the cluster.

According to Eric eilebrecht's blog, the fiber does not reduce the memory overhead or have better performance. When we need to use a large number of threads (such as more than 100), the total overhead of stack space of each thread increases linearly, and the overhead of thread switching takes too much time, it may even exceed the overhead of program execution. At this time, we need to design a management mechanism similar to the thread pool, and use a

A friend of the author works in China Telecom and is mainly responsible for the fiber optic business of China tietong. At a recent meeting, he told me about several failures encountered during Optical Fiber maintenance. The author selects two of the most representative introductions for readers, I hope you will learn from the article and reflect on the whole process of solving the problem. Fault 1: multiple

The EPON optical fiber access technology is still quite common. So I studied how to increase the network bandwidth of the EPON optical fiber access technology. I would like to share with you here and hope it will be useful to you. With the 1 Gbps fiber-to-the-Home (FTTH) technology, the deployment Speed of EPON fiber a

Debug fiber Interface interface with FPGA:Due to the needs of the project, the previous period of time debugging the optical fiber interface, recording some design experience.In the design, FPGA is used to control optical fiber module to complete the transmission of optical fiber data, FPGA uses Xilinx company's Sparta

If the company decides to deploy an optical fiber channel storage area network (SAN), then it should determine the supplier of the switch, because it is unwise to mix different brands. Fiber Channel switches need to communicate and cooperate with each other to manage the entire network. To ensure that the switches communicate well with each other, the best way is to select one of the three top switch suppli

We often hear about who drives the broadband is 4M or 10M or 20M and so on. So this is the same as what we call "how much MB/s" and "How many kb/s"?In fact, this is not a concept.Broadband operators in the broadband, such as 4M, is actually said 4M bit/s, that is, bits per second.And what we call the download speed is b/s, that is, bytes per second.Remember two relationships: 1b/s = 8 b/s;1 M =1024k.So 1M of fiber, that is 1M b/s =1 M/8 b/S =0.125 MB/

How to Set up a connection between a telecom Optical Fiber cat and a tplink Wireless Router In my home, the optical fiber cat is connected to the tp-link router, one desktop computer, two mobile phones and one tablet computer. I encountered a lot of thorny problems. I checked n more information on the Internet and finally solved the problem. I will summarize it as follows and share it with you. Back to bu

Whether in Wuzhou set up optical fiber or in the Taiping set up ADSL dial-up internet every time you set up the Internet all the time is encountered various troubles ... This time again to get n long, each problem is different. Summary of the operation process, easy to later encounter problems back to query from a microblog.Setting up dial-up internet for telephone lines:1, the voice separator points over the line access all-in-one machine, and then s

According to the ibdn standard, it is generally recommended that the communication room in each building be 12 cores. The building room should use 24 cores for consideration. First, we should know the number of cabling points on this layer and calculate the number of switches, whether or not to stack the connections between switches. If the core switch is dual-host Hot Standby redundancy, 6 cores will be enough (2 cores and 2 cores for each core ). If you do not need to stack a vswitch with 4 co

Of course, we choose the legacy interfaces in Chapter 1 to go to the analysis. Fiber _ Lookup () We mentioned earlier that during fib initialization, The config_ip_multiple_tables macro leads to two methods of Fib table initialization, so there is a situation where multiple route tables exist and no more route tables exist, let's first look at the absence of Multiple Route tables. Static inline int maid (struct net * Net, const struct flowi * handle,

The ethernet switch technology has become more mature and stable. Because the Ethernet switches in the industry share many similarities with the switches we usually use, the design of the Industrial Ethernet switch also uses the principle of the commercial switch. With the rapid development of Ethernet technology and its wide application in the commercial field, more and more industrial control devices gradually use Ethernet and adopt TCP/IP Protocol as the main communication standard. Although

? I. zoon's meaning and division principles ???? The function of Zoon in an optical fiber storage switch is similar to that of an Ethernet switch VLAN. It is mainly used to divide multiple logical zones in a switch to prevent storage connections of different applications from initiating broadcast packets, improves the utilization of Optical Fiber switches. ???? In principle, zoon must have at least two node

I. Mounting 1. New Fiber Optic Switches are available Note that the network port and Management port are different 2. wired Ii. basic configuration 1. Configure IP address and Change User Password A. The default IP address of the new optical fiber switch is 10.77.77.77. You need to configure the IP address for direct connection. B. log on to the machine and configure the IP address. Username: Admin. The

Prerequisites:Linux Root partition resizing requires the use of LVM for existing root partitions. If you select the default option when selecting partition settings during Linux installation, LVM is used for management. The command used to view the current root partition management mode is:Fdisk-lThe system column of the corresponding hard disk is Linux LVM, that is, it is LVM management and can be resized. Expansion steps:1. First, add a new disk, s
