Fiber Channel-based Ethernet switches are currently very popular. Do you need to select an appropriate Ethernet switch for your SAN or LAN? There are many similarities between SAN and LAN. For example, they all provide data storage and sharing. At the same time, there are also many differences between the two. To make a fair comparison result, let's talk about the differences between the two. LAN (LAN) generally refers to Ethernet, which is based on I

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

Solutions for faults of Huawei switches caused by network viruses. in the Internet era, we often encounter common problems related to switches of Huawei. The following describes the knowledge about network viruses, including in-depth analysis of Huawei switch faults. Huawei switch troubleshooting When a layer-2 Huawei switch fails, we often need to restart the device to solve the problem. After all, the lay

The appearance of Switch replaces the original HUB. First, let's first briefly understand the difference between a vswitch and a hub. A hub uses a bandwidth sharing method. For example, a hub is like a one-way street. The "10 m" bandwidth is used by multiple ports. When a port occupies most of the bandwidth, the other port will appear very slow. On the contrary, a vswitch is an exclusive Channel that ensures the bandwidth used by each port, such as a Mbps switch. It ensures that each port has a

Analyzing the differences between bridges and switches this article will introduce the differences and similarities between bridges and switches. Many people may not understand the relationship between bridges and switches. After reading this article, you will surely have a lot of GAINS, I hope this article will teach you more things. A Bridge, also known as a Br

More and more Wan solutions are now using Ethernet overSDH. On the surface, L3 switches and traditional routers can meet the needs of Wan interconnection. Therefore, many partners and customers have this question, what is the difference between the two in the wide area network connection? The following are some of my opinions for your reference.What is the difference between using a Cisco L3 switch and using a router as a WAN connection?First, the net

perform the task, and the current task executes a time slice and switches to the next task. However, the status of the previous task is saved before the switch, so that the next time you switch back to the task, you can load the state of the task again, from the time the task is saved to the reloading process, which is a 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'

Objective:In order to better understand the network of virtual machine, we must have a certain understanding of the switch of the virtual machine, below I have a vnetwork of the standard switches and distributed switch equipment and functions to do their own understanding and insight, I hope to have the help of friends. Vmware Vnetworkof standard and distributed switches1.1. What is the definition of a network? The network is the virtual platform of

Layer-3 switches have become an indispensable part of networking equipment. Here we analyze the solution of layer-3 switches in Internet cafes. In the Internet cafe environment, many netshers use a variety of software: games, QQ, video communication, and browsers. These applications will generate numerous data packets for communication between the Internet and the Internet, this transmission is based on the

Low-end switches are quite common, So I studied how to correctly select low-end switches. Here I will share with you, hoping to be useful to you. Currently, low-end switches in the Chinese market cover many brands from foreign network giants such as Cisco to domestic manufacturers such as Huawei and TCL, the price also ranges from about 50 RMB per port to several

I have made many attempts to learn more about how to test the energy efficiency of switches in the LAN. Can not clearly handle their own needs, so in the following article, there should be a satisfactory harvest. Many network equipment manufacturers today promise that their networks and switching devices are energy-saving, but few vendors can prove their actual use. Therefore, enterprise users must test the switch energy efficiency through a certain p

performance of Layer 2 and Layer 3 switches. Please pay attention to the comparison when considering device selection. Routing Technology The router operates on the layer 3 of the OSI model-the network layer. Its working mode is similar to that of the Layer 2 switch, but the router works on the layer 3, this difference determines that routes and switches use different control information when passing packe

Recently saw a lot of people asking about the switch, hub, router is what, function, what is the difference, the author on these questions to do some simple answers. First of all said Hub, that is, hubs. Its role can be simply understood to connect some machines to form a local area network. A switch (also known as a switched hub) works roughly the same as a hub. But there is a difference in performance: the way the hub uses shared bandwidth works, and the switch is the exclusive bandwidth. In

Cascade Extension The Cascade extension mode is the most conventional and direct extension, and some of the older networks use hubs as cascaded devices. Because the hubs were already quite expensive, most enterprises could not choose a switch as a cascade device. That's because most team users are connected to a hub from a port level on the hub. In this way, the access ability is greatly improved, but due to some interference and human factors, so that the overall performance is very low, only

The comparison between a layer-3 Switch and a router is in a large LAN. This function is perfect and helpful for understanding the layer-3 Switch. However, some manufacturers' switches can also directly connect to the Internet to provide the router function. Comparison Between Layer-3 vswitches and vrouters In order to adapt to the challenges brought by the deepening of network applications, the scale and speed of the network are rapidly developing. T

-managed switch performance. NETGEARProSafe smart switch security and connection are very easy. The operation on the front panel of the device chassis is the same as that on a non-Network-connected device. Gigabit and Fast Ethernet ports can form a star-type structure or Chrysanthemum chain stack. You can use a browser for quick configuration as necessary management. The NETGEARProSafe smart switch is perfect for adding basic management features to your non-NMS network. Install the NETGEARProSaf

purchase one or more hubs or switches.2. Differences between switches and routersFirst of all, the switch (aka Interchange Hub) function can be simply understood to connect some machines together to form a local area network. The difference between routers and switches is that it is useful to connect different network segments and find the most appropriate path

Huawei Agile Switch S12700 formally passed the OpenFlow v1.3 conformance Certification test of the Global SDN Test Certification Center, the world's leading information and communications solutions provider, and became the first box-type product in the world to pass the certification. This test also passed the S6720-ei, s5720-ei box switch, Huawei S-Series switches have become through the OpenFlow V1.3 Conformance certification tests the largest portf

It is easy to implement the vlan configuration functions of Huawei switches. In the current vlan configuration of Huawei switches, some people may not understand the specific vlan configuration methods of Huawei switches. It doesn't matter. I have read the following parameters, you will also become an expert. This is the first interface displayed when you connect
