Iperf is a pure bandwidth test software based on the C/S model. it can test the network card throughput. The advantage of iperf is to simply send and receive packets, to prevent hard disks from dragging down and affecting the test results. This document uses a gigabit network card Bcom5720 for testing. the environment CentOS6.4x64 installs iperf on both machines.

Analyzes the alarm control tasks and monitoring tasks of the Gigabit Ethernet switch. The two tasks of the alarm Group of the Gigabit Ethernet switch may not have a specific mode, therefore, the following alarm monitoring task Questions and Replies provided by netizens may not help you to obtain events. If no event exists, the operation is blocked.
An alarm group consists of two tasks: One alarm control ta
Currently, the mainstream Gigabit backbone switches have high forwarding capabilities and smaller sizes. They are suitable for common users. Among the six Ethernet switches we have tested, EDIMAX ES-5800R and LeaPComm6004 switch is not manageable switch, Accton es00008 and creative company Thinker3800 switch are network tube type switch, 3Com 4900 is support Layer 3 and Layer 4 switch, digital China D-Link DGS3308TG is a layer-3 switch.

Many may not have a special understanding of GE L3 switches. Here we will mainly introduce the future development direction of GE L3 switches. Now, the Internet industry is no stranger to the term "Gigabit Layer 3 Switch". In the construction of medium and large scale networks, mainstream network models with gigabit Layer 3 switch as the core are numerous. As a matter of fact, the emergence of GE L3 switche
With the development of China's exchange industry, various switches have been updated and upgraded. Here we analyze the comprehensive performance and Practical Application of Huawei's 10G core route switch, quidway S8500 series 10-Gigabit core route switch (S8500) is a new generation of high-performance core route switch developed by Huawei. It provides high-capacity, high-density, and modular layer-4 line rate forwarding performance, powerful IP rout
With the development of China's routing industry, Gigabit Routers have become one of the mainstream products in the market. It is also a good product for Internet cafes. ER5200 is a dual-WAN port high-performance gigabit router customized by Huawei 3Com for Internet cafes. It uses a professional 64-bit dual-core network processor and features a clock speed of up to 500 MHz, it also provides a wide range of
GE switches are still commonly used. So I have studied the full performance solution of the mainstream L2 switches with all-optical ports. I would like to share this with you and hope it will be useful to you. Recently, the F-engine S2200F series all-optical ports, 10-Gigabit L2 switches and F-engine S2200G series all-optical ports, which are independently developed by beacon network, were officially introduced to the market, this is an important step

The 1-gigabit layer-3 switch is quite common, so I have studied the 1-gigabit layer-3 Switch with high port flexibility. Here I will share it with you and hope it will be useful to you. After the success of the Gigabit center switch gmt7324, NETGEAR recently launched a more advanced layer-3 gmt7312 switch with more flexible port configurations.
GSM7312 provides a
Here we mainly aim at gigabit backbone switches and conduct a comprehensive evaluation of their performance in detail. In fact, for general users, what we value is cost effectiveness, rather than pursuing a good performance. Several Gigabit backbone switches provided for test are provided with detailed documentation. Here we first introduced the instructions of Digital China D-Link, which is very detailed.
GE switches are still commonly used. So I studied the performance test of GE switches and shared it with you here. I hope it will be useful to you. As the core connection device of an enterprise network, a vswitch has the primary performance standard to ensure the speed of the enterprise network. To help readers better understand the overall performance of GE switches, we use the industry-leading IXIA1600 Testing Instrument to test 9 main indicators involving Ge switches. Of course, the test con
GE switches are still commonly used. So I studied how to use parameters to evaluate the performance of GE switches. I would like to share with you here. I hope this will be useful to you, there are many types of GE switches and manufacturers that support Ge Ethernet technology on the market. How to choose suitable devices among these devices, it is a problem that requires careful consideration, time-consuming understanding, and difficult to weigh the choice.
Therefore, when evaluating and select
There are many things worth learning about GE switches. Here we mainly introduce the data interface types of GE switches. As the main connection device of LAN, Ethernet switches have become one of the fastest-growing network devices, at the same time, with this rapid development, the functionality of the Gigabit Switch is constantly enhanced, followed by the upgrading of the switch port and the addition of various special device connection ports to th
Gigabit Network is a fast Ethernet, its data transmission rate of 1Gbps, still using CSMA/CD access control mechanism and with the existing Ethernet compatibility, with the support of cabling system, can make the original Fast Ethernet smooth upgrade and can fully protect the user's original investment. At present, gigabit network technology has become a new network and transformation of the preferred techn

With the continuous development of network technology, we are more concerned about how people use computers
1. Introduction
The IEEE 802.3z Gigabit Ethernet Standard, adopted in June 1998, describes 3 physical layer interfaces (1000BASE-SX, 1000BASE-LX, and 1000BASE-CX) that are used for a universal link encoding and can be 1000mb/s transmitted. 1000BASE-SX, 1000BASE-LX interface using optical fiber as a medium, the farthest transmission distance of up to 5000 meters, so can be used in buildings or campus backbone network. The 1000BASE-CX interface is plan
