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
Let's take a look at the differences between Layer 2 switches, Layer 3 switches, and Layer 4 switches.

Control also means that data packets may be lost and the latency may increase.It can be seen that working on switches at a higher level, supporting quality services, relying on software operation and high-level management is an important position in modern enterprise networks. Next we will briefly introduce the performance, technology, application fields and development trends of the layer-4 switch.

Exchange technology is moving in two directions. One Direction is faster and faster, has jumped from the gigabit to the million trillion.
Another direction is from the initial 2-tier exchange to the 3-tier exchange, which has now been developed to the seventh layer of the Network application layer Exchange.
Figuratively speaking, the speed is more and more fast
1,Layer-3 forwardingYesRoute information is requiredThe route selection in the forwarding process determines the final egress of the message,L3 SwitchJust put thisRoute functions are integrated into the switch ChipGo.
2,Route SelectionExistExact matchAndLongest matchTwo methods.
2.1,Exact matchThat is, the destination IP address and the route address information
The 1-gigabit layer-3 switch is quite common, so I have studied the 1-gigabit layer-3 Switch with high port flexibility. Here I will share it with you and hope it will be useful to you. After the success of the Gigabit center switch gmt7324,
rate of the vswitch is, no matter how fast the data transmission rate is, network congestion always exists in the network. This tells us from one side that the absence of Service Quality Control also means that data packets may be lost and the latency may increase. It can be seen that working on switches at a higher level, supporting quality services, relying on software operation and high-level management is an important position in modern enterprise networks. Next we will briefly introduce th
(1) The animation effect here refers to the interface switch animation effect, we often fade in and out, right out of exiting and so on, of course, there are some advanced animation, this animation suitable for the game class, for the general app will appear too fancy.(2) We do not add any framework (Quartzcore) here or import any header files (QuartzCore.h), you can create an object, such as Animation1, di
adding network bandwidth, this is an effective and simple method, no matter how high the vswitch's backboard bandwidth is.
No matter how large the packet forwarding rate of A vswitch is, no matter how fast the data transmission rate is, network congestion always exists in the network. This tells us from one side that the absence of Service Quality Control also means that data packets may be lost and the latency may increase.
It can be seen that working on switches at a higher level, supporting

Experts tell you what a layer-3 switch is. Now every household has their own computer and understands what a layer-3 switch is. At that time, the layer-3 switch was based on software and the forwarding speed was very slow, later,
Layer-3 Switch: the principle of layer-3 switch is that two hosts A and B Using IP addresses communicate with each other through the layer-3 switch. When Site A starts sending, it compares its IP address with the IP address of Sit
Compared with the layer-3 switch, the layer-4 switch has a good improvement in its functions and features. Here we have explained the basic knowledge of the layer-4 switch. The amount of transmitted audio, video, data, and other i
