Switch type (rack style, fixed-profile with/without expansion slots The rack switch is a slot-type switch that is scalable and supports different network types, such as Ethernet, Fast Ethernet, Gigabit Ethernet, ATM, Token Ring, and FDDI, but the price is more expensive. A fixed-profile band-slot switch is a switch with a fixed number of ports and a small number of expansion slots, which, on the basis of support for fixed-port type networks, can support other types of networks, with the price ce
Windows Server 2012 Abstracts The topology of the physical network in the form of network virtualization, making it easier to achieve the goal of isolation and multi-tenant.
In network virtualization, one of the most important technologies is the extensible switch of Hyper-V.
(the example in this article is shown in Hyper-V under Windows 8, and the actual 2012 is the same)
The network is the most troublesome for those who use Hyper-V at first, and Hyper-V does not have the ability to access a
From the data, we can see that the current market demand for gigabit backbone switches is not high. Here we mainly analyze the functions and practical applications of mainstream Gigabit backbone switches. In the six Ethernet switches we tested, the EDIMAXES-5800R and LeaPComm6004 switches are not manageable
Recently opened the route for a new internet café, the Internet Café administrators ran to ask me, Internet cafes in the computer interconnection of the selected cable (hub) Good or switch good, Cisco's switch is not the best. People often say that only the right choice is not expensive. But how is the right choice? The common medium and small-sized network has two hundred or three hundred computers, many people reach thousands of units. They are connected by integrated cabling system switching
User-controlled switches are quite common. So I studied the types and functions of these switches and shared them here, hoping to be useful to you. A user-controlled switch is a dedicated switch for internal telephone exchanges between industrial and mining enterprises and other organizations. Its basic function is to complete mutual calls between users within the Organization, however, there are also incom
Stack switches are quite common, So I studied how small and medium-sized enterprises can purchase suitable stack switches. Here I will share with you, hoping they will be useful to you. According to the performance and user needs of the stack switches on the market, I think you need to pay attention to the following aspects when purchasing a switch. You can also
Internet cafe switches are still commonly used. So I have studied reasonable optimization solutions for Small and Medium-sized Internet cafe switches. I will share them with you here, hoping they will be useful to you. Some time ago, questions about how to apply for a ban on Internet cafes were also excited in some regions. The question about how to apply for a ban on Internet cafes is more of a social prob
Many people say that the Gigabit access switch is "Transformers" because it has excellent scalability and can meet more user needs, 12 out of the 18 Gigabit access switches with 2 Gigabit ports and 6 out of 1 gigabit port. Only two vswitches With gigabit copper ports are available. The most Gigabit ports are 1000Base-SX ports. Only Flexhammer24 of harbor technology has a 1000Base-LX port.
Among these switches
LAN switches are quite common, So I studied the basic technical indicators of LAN switches and shared them here. I hope they will be useful to you. There are many basic technical indicators for LAN switches. These technical indicators fully reflect the technical performance and functions of LAN switches. They are impor
Bridge (brouter) has the function of Network bridge and router.
5. In the network layer above the relay system, that is, gateways (Gateway).
When a relay system is a forwarder, it is generally not called a network interconnect, because it is simply a network extension, and this is still a network. High-level gateways are less used because they are more complex. Therefore, the general discussion of network interconnection refers to the use of switches

Digitalization, broadband, fiber-optic transmission, and segmentation are the future development trends of telecom networks and information networks. Therefore, it is necessary to build a comprehensive business platform unrelated to the business type or weak correlation, enables the network to carry multiple services. In this way, it not only achieves great economic benefits in design, construction, operation and maintenance, but also maintains good adaptability to business development, this max
A vswitch is an important part of a data center. We know that the most important function of a vswitch is to forward data between devices. If you compare devices in a data center to an isolated city, a switch is like a highway between cities. Of course, the highway can be crowded because of heavy traffic, or people may complain because of high charges. It can also cause major losses due to traffic accidents. Similarly, vswitches may encounter these similar problems in the data center. To solve t
Under normal circumstances, if you switch the workspace of Eclipse, you need to reconfigure eclipse, but you can change the. metadata/.plugins/in the original working directory. Org.eclipse.core.runtime Copy to the new workspace directory, overwriting the existing can, where. metadata/.plugins/ Org.eclipse.core.runtime is mainly about the workspace of some configuration files.Configuration issues after Eclipse switches workspace
For the context of Linux has been no special attention to its reasonable scope should be how much (about the concept of context switching, there are a lot of explanations on the Internet, again no longer repeat), the occasional notice during the day, the evening specifically looked at the next day load and after the load and after the following (server 1,8C/16GB, Run 1 mysql,8 Java processes, 1 rabbitmq):The context switch for the corresponding time period is as follows:Overall, the context is a
Switch learning feature). Layer three switch: based on the traditional two layer switch, the network layer forwarding technology is adopted. We know that the host communication of different networks generally requires router forwarding, if only a local area network is divided into multiple subnets, inter-subnet communication using routers, then the communication efficiency between these subnets will be due to the router interface low speed, complex and greatly reduced. The IP analysis function
