The next generation of firewall wins the application layer, and the next generation wins the application layer. Why is next-generation firewall superior to application layer? Almost no one doubts about the important position of f

The application of the anti-DDoS principle and SQL in keywords in EF, sqlef Suddenly realized the importance of words, so I began to write my first blog, with the goal of keeping a close record for ease of understanding. At the same time, I also hope that the brick-and-mortar market can play a role in promoting mutual learning. You are welcome to express your thoughts and thoughts! Background: During the el

needs of the project. Therefore, it should be used as the bottom layer to provide basic support for the upper layer. We name itHardware Abstraction Layer(Hardware abstract layer ). The chip is not enough. We usually expand some functional modules out of the chip to meet specific project requirements, such as sensors,

during the transmission of the data. The data is encrypted at the sender end and decrypted at the receiving end. Encrypt and decrypt data using the encryption key. The presentation layer is also responsible for compressing the files, compressing the file size by algorithms, and reducing transmission costs. Application Layer

kinds of information that must be used for network communication: the protocol that the connection uses, the IP address of the local host, the protocol port of the local process, the IP address of the remote host, and the protocol port of the remote process.When the application layer communicates data through the transport layer, TCP encounters a problem that pr

Computing middle layer of a report application, and computing middle layer of a report Application In traditional report applications, there are generally three ways to compute source data: 1. The report tool directly connects to the database to fetch data, and the source data is computed by submitting SQL statements c

OpenVPN-ng: The application-layer tunnel for Mobile Life, And openvpn-ng Application LayerVPN makes people think that it is always a good thing and a way to escape from supervision. In fact, VPN has become the only synonym for escaping from supervision. You see, no matter what technology, IPSec, or WEB Proxy, as long as it is the technology that encrypts the orig

Drive development will certainly encounter the application layer and the core layer of communication problems, first of all, the kernel layer and the application layer of communication can be divided into two aspects, the first is

The network technology develops rapidly, the Ethernet occupies the dominant position. In order to meet the challenge of deepening the network application, the scale and speed of the network are developing rapidly, the speed of LAN has been improved from the initial 10mbit/s to the 100mbit/s, and the Gigabit Ethernet technology has been widely used. For users, in the premise of reducing costs, to ensure the high reliability of the network, high-perfor

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

Network Layer Routing and Application Layer Routing In the IP connection network, the correct communication between hosts is ensured by the correct routing. Here, the routing is not a hardware router, but a routing policy. First, summarize the routing-related addresses in the Network: 1. MAC address: used for hop-by-hop routing in the Link
