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

The optical fiber access network is still quite common. So I have studied the comprehensive solution of the EPON optical fiber access network. I will share it with you here, hoping it will be useful to you. At present, the optical fiber access network is facing a series of technological and business model revolutions and challenges. Changes in user business needs

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

Fiber home HG-110 (adsl/router) Vulnerability Release date:Updated on: Affected Systems:Fiber home hg-110 1.0.0Description:--------------------------------------------------------------------------------Fiber home hg-110 is a router of beacon technology. A security vulnerability exists in the implementation of the fiber home hg-110. Attackers can exploit this

Fiber To The Home, optical Fiber To The Home, refers To The optical network unit (ONU) installed in The Home user or enterprise user. Its significant technical feature is not only to provide greater bandwidth, but also to enhance the transparency of the network on data formats, rates, wavelengths and protocols, and to relax the requirements for environmental conditions and power supply, simplified maintenan

Hello everyone, our picture is stored with another pat on the Cloud (Upyun). Today, there is a sudden failure: Hangzhou Purple Tunnel construction, and Pat Cloud 2 of the city area fiber are dug, affecting the normal service of the cloud, resulting in 11:00-13:30 can not upload pictures in the garden. This brings us trouble, hope you understand!has been basically restored to normal, but because the use of backup lines, upload speed will be affected by

CISCO mds FC optical fiber switch configuration reference(1) There are several concepts that must be clarified (different from brocade ):(1) brocade divides zones directly. While mds divides zones under vsan, mds can divide several vsan first, and each vsan includes several zones.(2) brocase: the default port is open, while the default port of mds is closed.(3) mds has a Default zone: "The Default Zone ". if no zone is set, all the ports are in this z

Topic Links:https://vjudge.net/problem/POJ-2570Main topic:Some companies decided to build a faster network called the "Fiber network." They have built many sites around the world, and these sites function like routers. Unfortunately, these companies are arguing about the wiring between the sites, so that the "fiber optic network" project is forced to terminate, leaving behind the lines that each company lay

Wu Jian Company of America Project Overview The overall design requirements for the campus integrated Cabling System are: advanced, practical, flexible, scalable, standard, reliable and economical. At the same time, the whole and expansibility of the system should be considered, and the whole design planning and investment estimation should be carried out for the construction of the following buildings in the park. Backbone Subsystem Design Mainly for the transfer room to the floor of the we

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

In addition to FCIP, another method is iSCSI, which converts user requests into SCSI code and encapsulates data into the IP package for transmission over Ethernet. To connect a geographically dispersed SAN, the FCIP Protocol can only be used for Fiber Channel Technology connections. In contrast, iSCSI can run on an existing Ethernet. SAN connections, such as FCIP and iSCSI protocols, can provide higher performance, validity, and fault tolerance based

Optical fiber is outdated? Gbps Space Optical Communication in the UK! According to foreign media reports, researchers at the University of Oxford have achieved free-space optical communication at a rate of up to Gbps. Such optical communication technology does not need to use optical fiber. The researchers pointed out that the maximum rate of the communication system can reach 3 Tbps. The study, led by
