VLAN Technology and Layer 3 Switching Technology

In network scale construction, it is generally constructed in the form of a three-layer switch, and this type of network construction scale is relatively large, so it is also widely used in network model applications. At present, all walks of life in our country have a lot of demand for this technology, but the traditional technology can no longer meet the actual needs, and various disadvantages have appeared in the process of application. In order to meet the actual needs, a new VLAN technology will be researched. In traditional technology, if more than two or more machines are working at the same time, conflicts are prone to occur, and there will be serious data loss. Once a conflict occurs during this process, the data to be transmitted will be terminated, and there may even be a risk of loss, so this will cause a great waste of resources. Relevant operators in this process can only transmit information here after the conflict is over. In order to avoid conflicts, our country has also developed a new form, which is to use network switches to work.

VLAN technology

VLAN means virtual local area network. It analyzes the network in the area, summarizes the main content, and combines various logical problems to apply it to devices. Compared with traditional networks, it avoids the disadvantages of physical division. Therefore, from a virtual point of view, the technology is organized so that it can realize the exchange capability on the local area network, so as to meet the actual needs. This technology requires the application of network management software in the management process, so it is not bound by physical location, but encompasses the entire area and does not work in conjunction with the site. During the application of this technology, it will also be divided according to functional requirements and logical requirements and classified according to different discussion groups, so that each organization becomes an independent individual, enabling it to transmit information to organizations in various fields member. There is a certain gap between each group, and the support of routing is needed between each group to ensure the quality of communication. But after the VLAN is applied, relevant operators can search the network more conveniently and establish corresponding broadband networks. In this way, the network management personnel can use the logic in the network group to find and allocate the conflicting data of the user, and transmit it to the corresponding area, avoiding physical factors and achieving the effect of direct connection.

Therefore, VLAN also fully embodies the advantages of modern network technology, such as fast speed, flexibility and convenience. For now, VLAN is a relatively advanced technology, which can solve the disadvantages of our country’s network, and at the same time improve the flexibility of the network, and also guarantee security issues. Therefore, this technology has now become a measure of my country’s network. an important indicator.

Layer 3 switching technology

Layer 3 switching technology is also called high-speed routing technology. At present, my country’s traditional switching technology generally operates on the data layer in the OSI network standard model, and the data layer is generally in the second layer. The third layer switching technology needs to be established in the network model, the main purpose is to realize the rapid transmission of data packets, it combines the functions of the data layer, and on this basis, it increases the forwarding ability of the router. To sum up, this technology actually turns the traditional switching technology into a forwarding technology, and also solves the bottleneck problem of the traditional router network, especially in terms of hardware. At present, the interface of the second-layer switch generally converts data to the bus, but in the layer 3 switch, the router mainly has hardware modules to work. This way of working. The use of routers to exchange data information eliminates the disadvantages of traditional exchange modes and increases the exchange speed.
