A server Load balancer device is also called a "layer-4 to layer-7 switch". What is the difference between layer-4 and layer-7? First, differences in technical principles. Layer-4 Server Load balancer determines the final internal server through the destination address and p

Note: This note is written from a programmatic point of view, which is what I think is helpful for programming, not from the perspective of a network expertise. The following illustration shows the different partitioning of the architecture of the computer: the OSI seven-layer protocol architecture, the architecture of TCP/IP, and the architecture of the five-tier protocol: The following figure illustrates the changes that the application process's

Currently, few second-layer switches are used, mainly because of their performance limitations. We believe that with the development of the communication industry, switches with better performance will continue to emerge. In today's network construction, layer-3 switches are recognized and praised by users for their efficient performance and superior performance/price ratio. At present,

What are the differences between layer-2 and layer-3 Ethernet switches and their basic types? The following are some comparisons: after reading this article, we will be able to fully understand the layer-3 Ethernet switch. Next we will talk about the three-layer Ethernet switch process. VLAN segmentation is used to iso

The linux OSI Layer-7 model, TCP/IP protocol stack, and the structure of each layer reveal big secrets. The osi protocol stack When I learn Linux, I know the OSI model even if I am a little cute. What ?! You don't know !!! Okay, this secret is taken away. Thank you ~~~ I,Two protocols (1OSI protocol model (layer-7) International ProtocolPDU: The data unit transm

Summary: Play based on the MAC address is two layer (virtual MAC address receives the request, then assigns to the real MAC address),Based on the IP address play is three layer (virtual IP address receives the request, then assigns to the real IP address),IP address plus port play is layer four (the virtual ip+ port receives the request and then assigns it to the

Keras provides many common, prepared layer objects, such as the common convolution layer, the pool layer, and so on, which we can call directly through the following code: # Call a conv2d layer from Keras import layers conv2d = Keras.layers.convolutional.Conv2D (filters,\ kernel_size , \ strides= (1, 1), \ padding= ' v

Unlike UDP, TCP provides a reliable, connection-oriented, byte-throttling service. The reliability of TCP protocol mainly has the following guarantees: (1) The application data is segmented into the data block which TCP thinks is most suitable for sending. This is controlled in part by the "MSS" (maximum packet length) option, which is often referred to as a negotiation mechanism, which sets the length of the maximum block of data that TCP travels to the other end. It is noteworthy that MSS can

ASP. NET development, from Layer 2 to Layer 3 to object-oriented (5), asp.net object-oriented This is the last article of a series of blog posts. It is also intended for beginners. I hope you can have a better understanding of ASP. NET programming.ASP. NET development, from the second layer to the third layer, to the o

With the popularization of broadband, a variety of network applications in depth, our local area network is shouldering heavy traffic. Network system of audio, video, data and other information transmission is full of bandwidth consumption, we have to provide these data traffic differentiated services, so that the time delay sensitive and important data first pass, this has to consider the fourth layer Exchange to meet policy-based scheduling, QoS (Qu

Table 1-1 is the TCP/IP four-layer model and the OSI seven-layer model table. We correspond the OSI seven-layer network model with the Linux TCP/IP four-layer conceptual model, and then categorize the various network protocols. Table 1-1 TCP/IP four-layer model and OSI seve

Always feel that the model layer is only used to manipulate data, a lot of business processing in the controller, there is a claim that business logic is more suitable for the model layer, do not know which processing better! Look at the tp5.0, as if the business logic in the model, and then read some stickers, many say business logic in the model better. Links: https://ruby-china.org/topics/19292 The busi

Layer behavior (implicit animation), layer behaviorLayer behavior Now let's make an experiment and try to directly animation the layers associated with UIView instead of a separate layer.
