Both layer-3 switches and routers work on the layer-3 network. packet forwarding (or switching) based on IP addresses is not very different in principle. These two terms tend to be unified, the exchange router and route switch refer to the same thing. We can consider a layer-3 switch as a multi-port router. However, from the perspective of the historical developm

scenes using the temporary effect of vision; because each frame requires 798x798 pixels, the amount of data required per second is as high as 2409x798 ^ 2x3) /1024 ^ 3 = 4.286 GB! Given the limited excitation time of a common laser, felix3d cannot provide such a high bandwidth and frame rate. A 3D image in Felix can only reach 10 thousand pixels at most, perspecta can display nearly 1 billion individual pixels. To achieve such high display accuracy,

Careful users may find that in the previous login example, users can get three pop-up errors: "Empty Password" "Wrong Password" "user does not exist ", the first two of them are made in the U layer, but "user does not exist" is made in the C layer (I am referring to this string) or is the bridge established at the beginning, I used the "xistream bridge" here to explain the "Great River Bridge", so I intentionally turned a useless circl

Example: 3026 2012 5012. The value of 2nd bits is 0 ~ 4 indicates that it is a layer-2 switch. 3550. The fifth digit is 5 ~ 9 indicates that it is a layer-3 switch.

directly superimposed on the Layer 2 switching high-speed backend.On the board bus, it breaks through the interface speed limit of traditional routers, and the speed can reach dozens of Gbit/s. Calculate the bandwidth of the backboard.These are two important parameters for the performance of a layer-3 switch. The simple routing software simplifies the routing process. Most of the data forwarding, except fo

layer-2 switching, and the price is relatively low. Since there are many features and the price is low, it should be favored by enterprise users. How should we select switches?　How to select a vswitch:　(1) Selecting trusted technical indicators: Like any electronic product, when selecting a layer-3 switch, we should first analyze the performance indicators of various products. However, for example, switching capacity Gbps) and

Through the introduction in the previous two chapters, we have learned some about the basic concepts of XSLT and its conversion process. Next we will learn the specific syntax of XSLT. When it comes to syntax, it's always boring. You can simply browse it and study it carefully when you really need XSLT. 3. Element Syntax of XSLT 3.1 XSL: Template and XSL: Apply-templates 3.2 XSL: value- 3.3 XSL: For-each 3.4 XSL: If 3.5 xxsl: Choose, when,
