cpp handshake

Compared with socket developers, the TCP creation and link Division processes are automatically created by the TCP/IP protocol stack. therefore, developers do not need to control this process. however, it is helpful to understand the underlying TCP operation mechanism.In addition, a written examination such as a network protocol engineer is almost mandatory. the enthusiasm of the company for this issue is beyond my expectation :-). This problem is sometimes emphasized before the interview in the

CPP -- positive code, reverse code, and complement ~ With the discussion of integer overflow, cpp -- anti-code The long dispute (http://www.cnblogs.com/dotnetcrazy/p/8059210.html) was mentioned before, so we don't need long to give an example here. Use int. Can take a look at this article (http://www.cnblogs.com/dotnetcrazy/p/6743530.html), better understanding of this article (this article does not contin

CPP-understanding memory storage with the help of artifacts VS, cpp -- I also want to know this before. The first is not to learn the underlying layer, but to understand the concept of online search. The second is the end of the story. The example is also complicated, it may be difficult for the non-C direction, so I have never understood it. Today, I accidentally found out that I had to go through the me

1. TCP (Transmission Control Protocol) Transmission Control Protocol TCP is the transmission control protocol used by the host to control the host layer. It provides reliable connection services and uses three handshakes to establish a connection: 2. Three-way handshake The first handshake: host a sends a packet with a SYN = 1, generates a data packet with seq = x at random to the server, and host B is know

http://blog.csdn.net/dotnetpig/article/details/6776999 Recently interviewed a lot of companies, in addition to Baidu, other companies Taobao etc will ask you TCP three handshake in the end is what, why is three times shaking hands instead of four times shaking hands. After reading this article, I am sure I will find the answer. 1, establish the Connection agreement (three times handshake)(1) The client sen

TCP three-way handshake/four-way handshake explanation 1 establish a connection protocol (three-way handshake) (1) the client sends a TCP packet with SYN flag to the server. This is packet 1 during the three-way handshake. (2) The server responds to the client. This is the first packet in the three-way

Three-way handshake to establish a connection: First handshake:The client sends the SYN Packet (SEQ = x) to the server and enters the syn_send status. wait for confirmation from the server; The second handshake:When the server receives the SYN packet, it must confirm the customer's Syn (ACK = x + 1) and send a SYN Packet (SEQ = Y), that is, the SYN + ACK packet, the server enters the syn_recv status; The third handshake:The client receives the server'

TCP/IP protocol three-way handshake and four-way handshake (establish connection and disconnect), tcpip 1. TCP/IP protocol Overview The TCP/IP Protocol (TransmissionControl Protocol/Internet Protocol) is also called the transmission control/Internet Protocol and network communication Protocol. This Protocol is the basis of the Internet. TCP/IP is the basic communication protocol used in the network. Althoug

TCP three-way handshake and four-way handshake Three-way handshake TCP connections are connected through three handshakes. First handshake When the client initiates a connection request to the server, the client sends the synchronous sequence number SYN to the server. Here, we set SYN to m and wait for the server to c

Tcp establishes a connection and disconnects. This problem is frequently asked during many interviews. Although many people know that tcp has three handshakes and four handshakes, however, if you want to explain the tcp connection and disconnection in detail, it will be a bit problematic ....

on the slowest point. If a and B constitute a software based on TCP communication, the execution efficiency of the software is measured by the efficiency of A, B, and the overall network, the network is the slowest point. The network delay time is limited by the existing physical level and cannot be solved. In program development, the fewer network transmission times, the better, the less time the network latency is. In fact, the purpose of TCP three-way ha
