Many SME internal network structures are simple, with only one switch connecting all employees and servers together and then accessing the Internet through fiber optics. Of course, in order to ensure the security of some hosts and split the internal broadcast packet to improve the network transmission speed, take such as partition VLAN, the allocation of different subnets to achieve. By partitioning VLANs, clients on different ports on the same

The layer-3 switch you know works like this. It works like a layer-3 switch.
Why do we say that the L3 forwarding performance of a layer-3 switch is much higher than that of a router? Sometimes it is mentioned in many books that the software of the router is also very powerful and can almost achieve the speed limit forwarding capability. However, it is unlikely

A Router operates at the network layer, the third layer in the OSI Layer-7 network model. It works by removing the information of the second layer (data link layer) of a packet (including a broadcast packet) received on the Network (called "unpacking "), and view the layer-3 Information (IP address ). Then, the route of the data packet is determined based on the ro

Because Android does not provide components such as slide switches, we need to implement a custom view component to achieve the slide switch effect.
Here is an example code, which includes three classes: switch component view, status listening interface, MainActiv
Since Layer-3 switches can be considered as composed of routers and common switches, You can first try to install some modules with routing functions during assembly, in this way, there is a layer-3 Switch rich in routing functions.
Its functions are equally powerful. Recently, the price of vswitches has been greatly reduced. Some models of some domestic brands have fallen below RMB, which is almost the same as that of hubs. With the updates of People
In daily life, the Internet access will certainly involve wireless switches, which provide users with exclusive point-to-point connections. data packets are only sent to the destination, so as to avoid a significant reduction in the bandwidth of all ports when the data volume is large, therefore, selecting a high-performance wireless switch saves a lot of trouble for future work.
