From the data, we can see that the current three-tier switch is still the most demanding exchange technology in the market, here we mainly let you fully understand the three-tier switch, in order to help enterprise users better understand the meaning of layer-3 Switch, under
one undertaken by the traditional router, but a wide variety of broadband access devices, such as broadband routers and VPN firewalls. Three-layer switches that use VLAN routing instead of traditional routers have emerged. hardware-based route forwarding is more efficient and faster than software-based route forwarding of traditional routers.
Now enterprises have a better choice to deploy VLANs, that is, layer
Three-tier switching has been widely used since its concept was proposed. Although it has only been a few years, multiple access ports and low prices provide a perfect solution for small network users, otherwise, it would take a second step, so that layer-3 switches are also interconnected over the Internet.
In today's network construction, layer-
1. IntroductionIn today's network construction, the new three-tier switch has become our first choice. It is recognized and praised by users for its efficient performance and excellent performance and price ratio. At present, layer-3 switches have been widely used in enterprise network/campus network construction, Smart Community Access, and many other occasions.

Exchange Technology: it is a router because it can operate on the layer-3 of the network, it is a type of routing that understands a device and can act as a route decision. It is a switch because it is extremely fast and almost achieves the second-layer switching speed. Who are the advantages and disadvantages of
Compared with the original vswitch and vro, the routing speed of the layer-3 vswitch is generally 10 times faster or dozens of times faster, and can implement line rate routing forwarding and other functions, the exchange LAN technology enables dedicated bandwidth to be exclusive to users, greatly improving the efficiency of LAN transmission.
The introduction of LAN switches enables dedicated bandwidth betw
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
bottleneck of the local area network, many enterprises use layer-3 switches to build local areas in their internal, school, and residential areas. Compared with the traditional concept, layer-3 switching is proposed. The traditional switching technology operates on the Layer

Layer-3 switches are quite common, So I studied the technology introduction and Practical Application of layer-3 switches. I would like to share with you here, hoping to help you. A vswitch is the "cornerstone" for building a network platform, also known as a network switch.
How to configure a switch to implement layer-3 switching first, let's take a look at how the switch sets the application environment of layer-3 switching technology. In order to enable communication between VLANs, single-arm routi
domain, thus optimizing the LAN performance. However, it is a device that is transparent to the upper layer (Layer 3 or above) protocol and cannot effectively prevent broadcast storms. Therefore, a router is required. Vrouters play a key role in subnet interconnection, security control, and broadcast storm restrictions. However, complicated algorithms and low da
Differences between traditional switching and Routing
After a layer-3 switch routes the first data stream, it will generate a ing table between the MAC address and IP address. When the same data stream passes through again, the table is directly routed from the second layer instead of the second
VLAN intercommunication is achieved through layer-3 switching. Generally, routers are rarely used within an enterprise network. In a production environment, inter-VLAN communication is mainly implemented through layer-3 switching. A layer-
Layer-3 switches use a hardware exchange mechanism to implement the IP routing function, which greatly improves the running efficiency of the entire network and solves the problem of traditional router software routing speed. To describe the role of a layer-3 Switch in many
