handshake. Among the many replies, the author wrote: the essence of this problem is that the channel is not reliable, but the dual-producer communication needs to reach an agreement on a problem. to solve this problem, no matter what information you contain in the message, three-way communication

What is the industrial Internet of things?In short, it is the specific application of the Internet of things in industrial control.What is SSL/TLS?SSL (secure Sockets layer Secure socket), and its successor Transport Layer Security (Transport layer Security,

Protocol) is on the network layer. 4, the Transport Layer (transport layer)in the OSI model, the transport layer is the highest level responsible for data communication and is the only responsible overall numbertransmission and control of the layer, to ensure the reliability of the connection, directly to run on a different hostprovide communication services on

[Scenario description] The client is started, and the server is started. The client initiates a connection The client sends a packet containing the four bytes of "Hutu" Client disconnection, server disconnection [Process diagram]No picture, no truth! [Socket status change diagram]No picture, no truth! Establish a connection protocol (three-way handshake

After understanding, it should be said that at least three times to ensure reliable transmission.See an online post http://www.cnblogs.com/TechZi/archive/2011/10/18/2216751.htmlThat said, "I Google the answer to the question found that the network on the" three handshake "process is described in detail, but for why the need to" three handshake "to establish a con

What is HTTPS HTTPS is ' Hyper Text Transfer Protocol ' with Secure Sockets Layer (SSL) The main idea of HTTPS is to create a secure channel on an insecure network and to provide reasonable protection against eavesdropping and inter-person attacks when the appropriate encryption packets and server certific

, serial line, etc.) to transmit data. Protocols in TCP/IP Here's a brief description of what the protocols in TCP/IP are capable of, and how they work: 1. Ip Internet Protocol IP is the heart of TCP/IP and the most important protocol in the network layer. The IP layer receives packets from a lower level (network interface layer such as an Ethernet device driver) and sends the packet to a higher--

LEAP together with existing user names (such as Windows Domain Names) and passwords. In fact, this is why LEAP is easy to deploy. There are also many other unfamiliar EAP types that can be used with 802.1X. For example, the EAP-TLS supports two-way authentication based on digital certificates. PEAP (protected EAP) supports MS-CHAPv2 password authentication on en

What is the working principle of HTTP? How to optimize the HTTP protocol ?, Protocol Working Principle Optimization made by http1.0 Bandwidth: latency has been solved at this stage: 1. browser blocking: the browser can only connect to the same domain name with four connections at the same time. latency: 2. DNS query: The Browser needs to know the IP address of the target server to establish a connection del

Cython to write multiple threads in bare mode. If it is used as a high-concurrency server, multiprocessing directly spawn out sub-processes, and frameworks like pulsar help you with fine-grained locks + STM + TLS: Fine-grained locks are used to solve GIL. Today's mutex uses futex to implement it in the user State, which is much faster than before. Using STM

programs with shared memory will not decrease. you will fall down in C, and there will be no less here. So let it go. the CPython level does not mean performance .. Python is easy to occupy multiple cores. if it is used for scientific computing, you can use Theano/NumbaPro/numexpr to optimize numpy computing or Cython to write multiple threads in bare mode. if it is
