different switches

built-in Ethernet bus, the switch can be regarded as an interconnected system consisting of multiple Bus switches. Each vswitch port corresponds to a Core Bus, which is an order of magnitude higher than a backboard bandwidth Bus. The backboard Bus is connected to a Switch Engining engine. Data Packets between different ports are transferred to the switching engine through the backplane bus, and are exchang

, reducing the number of context switches can improve the efficiency of multi-threaded threads. The methods for reducing context switching are lock-free concurrent programming, CAS algorithms, using minimal threads, and using the coprocessor. no lock concurrent programming . Multi-threaded competition, will cause context switching, so multithreading data, there are some ways to avoid the use of locks, such as the ID of the data according to t

can even be said to be slightly faster. Why is concurrent execution slower than serial? This is because of the overhead of line threads creation and context switching .Context Switches ViewedThe Vmstat command can be used to view the number of context switches under a Linux system, and here is an example of using Vmstat to view the number of context switches:CS (context switch) indicates the number of cont

context switch .It's like we read two books at the same time, when we read a technical book in English, we found that a word didn't know, so we opened the Chinese-English dictionary, but before we put down the English books, the brain had to remember how many pages the book read, and then, after checking the words, could continue to read the book. Such a switch will affect the efficiency of reading, the same context switch will also affect the speed of multi-threaded execution.How to reduce con

visual| compilation The compiler for Visual C # is significantly different from the compilers of previous programming languages. The biggest difference is that the previous program compiler is to compile the program code to build the machine language that can be used directly for the computer. Although the Visual C # compiler can also compile the written program code into an EXE or a DLL file, this file is just an Il file (intermediate language), whic

A prefecture-level government generally uses two networks to build an office network and a network of public services. Port network can be used hammer series of switches to form a office network, the whole network has the following three major features: Million trillion core The equipment of the core layer of the office network needs to adopt large capacity and intelligent multilayer switching features. According to the development of network techno

In the enterprise wireless LAN, wireless switches are used for integrated data transmission and distribution. Its management function enables our data to flow in an orderly manner. In the work process, wireless switches will also lag behind. So how should we optimize the data exchange of wireless switches? Different wa

GE switches are still commonly used. So I have studied the parameters and functions of GE switches. I will share them with you here, hoping they will be useful to you. When evaluating and selecting equipment, we should pay attention to the following aspects: product type; gigabit port density and type supported by the product; product performance; after-sales service; management features and security and re

Fiber switches are quite common, So I studied the most suitable fiber switches for small and medium enterprises. With the increasing number of network data and the frequency of network applications, many enterprises have begun to realize that they need to build their own storage system networks to meet the increasing data storage performance requirements. Currently, the most popular data storage Network is

With the development of the exchange industry in China, the wide application of gigabit smart switches has been greatly promoted. At present, Gigabit smart switches have improved many shortcomings and provide users with a good user experience. Tcls4rjsfb of TCL Network Equipment Co., Ltd. is a gigabit smart switch with Simple Network Management and belongs to working group-level network equipment. Based on

Horizontal virtualization cluster of data center Switches Virtualization Technology is a buzzword in the data center, including horizontal virtualization, vertical virtualization, one virtual machine and multiple virtualization, and NVO3 virtualization. Today, we will focus on horizontal virtualization. Taking Huawei CloudEngine 12800 series as an example, let our friends know the origins and development history of this technology, this article brief

Layer-3 Switch for Cisco switches Although single-arm routing solves the communication problem between different VLANs, it also has its fatal defects: -The single arm itself is the Backbone link of the network, which is easy to form a network bottleneck. -The sub-interface relies on physical interfaces, and the application is not flexible -You need to view the route table for each vlan forwarding, wasting

Layer-3 switches and routers are widely used in various fields, including hub hubs. The most fundamental difference between a layer-3 Switch and a router is that a layer-3 Switch also has a "routing" function, which is consistent with the routing function of a traditional router. However, layer-3 switches and routers are quite essentially different. 1.

power to avoid conflict. When an AP is started, the wireless switch can intelligently determine its firmware version. If necessary, a new version is pushed to automatically upgrade the AP. Because a wireless switch is a dedicated system, a dedicated tunnel protocol and Management Protocol are required between the AP and the switch. Therefore, a lightweight AP of the same manufacturer is required for use, systems of different vendors are often incompa

With the help of today's advanced smart enterprise networks, enterprises can effectively deploy e-commerce and other applications, thus realizing the optimized combination of labor and the globalization of business. These powerful networks can connect many remote sites, branch offices, mobile employees, partners and customers to provide services for thousands of users. However, there is still a problem that all networks are increasingly threatened by the increasing number of security risks on En

An improper port connection between Ethernet switches in Ethernet may cause a network loop. If the related switch does not enable the STP function, such a loop will lead to endless data packet forwarding, forming a broadcast storm, this causes network faults. One day, we found a problem with a VLAN in the campus network performance monitoring platform-the connection between the access switch and the campus network was interrupted. Check the aggregatio

Virtual Storage Technology is undoubtedly a hot technology in recent years. In addition to traditional host manufacturers, disk array manufacturers, and backup software manufacturers, there are also a new generation of products, smart switches, in addition, the product has been launched under the standard of 2 GB Fiber Channel Protocol, and has a place in the current storage virtualization products and solutions. As we all know, in traditional SAN sto

Currently, the smart switch technology has become increasingly mature. Here we mainly introduce the performance and features of mainstream smart switches in the market. Virtual Storage Technology is undoubtedly a hot technology in recent years. In addition to traditional host manufacturers, disk array manufacturers, and backup software manufacturers, there is also a new generation of Intelligent switches, w

Analysis of Optical Switch practice process Once a product supplier is determined, do not change it easily, because mixing products of multiple brands can easily lead to problems. Whether fiber switches can communicate normally is a key factor to ensure the stability of the entire network. Gartner analyst Robert Passmore said: there are standards for communication between fiber switches, but it is far from
