The browser parses the HTML code and requests the resources in the HTML code6. The browser renders the page rendering to

How to perform a dynamic debug tracing pattern similar to JSSE provided in eclipse Column: Java-djavax.net.debug=ssl,handshake,data,trustmanager First determine that this is a parameter that belongs to the Run-time VM, and that parameter is-djavax.net.debug=ssl,handshake,data,trustmanager, so next we need to add this parameter to the VM's parameters Click ' Run ' on the ' top menus select ' Run Configura

First open the http://www.baidu.com this URL to grab the packet. First, enter the HTTP filter in the filter Find the Get/*/http/1.1 We can see that HTTP appears after three TCP records, which also makes it more confident that HTTP is based on the TCP protocol. First-time TCP handshake The client sends a TCP, the flag bit is SYN, the sequence number is 0, which represents the client request to establish a connection. Figure below

Three-way handshake Three-wayHandshakeA virtual connection is established through three-way handshakes.1. (Client)-> [SYN]-> (Server)If the Client communicates with the Server, the Client first sends a SYN (Synchronize) packet to the Server, telling the Server to request a connection.Note: a syn packet is a TCP packet with only the SYN flag set to 1. it is very important to realize this. Only when the Server receives the SYN packet from the Client can

Brief Description:Mptcp still carries out three handshakes in accordance with normal TCP, only adding MPTCP-specific information to the handshake process.Build ProcessThree times the handshake process is as shown: the first SYN packet sent by the left client carries the key of the client itself, the right side of the Syn/ack carries its own key, and the last left client sends the last ACK with both sides of

Establishment and release of TCP connections (three handshake with four waves)TCP is a connection-oriented transport layer protocol that provides a reliable, full-duplex, byte-stream-oriented point-to-point service. The HTTP protocol is implemented based on the TCP protocol. (although as an application-level protocol, the HTTP protocol does not explicitly require that the TCP protocol be used as the transport layer protocol, but because of the HTTP pr

Handshake for the first time:When the link is established, the client sends a synchronous (SYN) Request packet to the server, enters a status waiting for the server response (syn_sent), and there is a dedicated synchronization sequence number to identify the link (synchronize sequence numbers);Explain:SYN (synchronous): is a handshake signal when a TCP/IP link is in hand.ACK (Acknowledgement): Is the acknow

Indicate the source and author's contact information during reprinting. Author's contact information: the communication protocol between ActiveSync and Window Mobile is not complex, and TCP/IP is run on RNDIS + USBNET, the application layer protocols on TCP/IP include RAPI and RRAC. Some time ago, I completed the implementation of the RAPI and RRAC protocols on the PC end and the device end. In this series, we will analyze their principles and implementations for the reference of friends who wan

Address: http://www.55linux.com/cisco/559.html 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, there are network protocol engineers such as the written examination, almost mandatory content. my company is very enthusiastic about this issue :-). This problem is som

This Protocol is very important. Here we will sort out its links and releases. The first is the three-way handshake: 1. The client initiates a request. For example, if the server sends packets SYN = 1, ACK = 0, an initial sequence number is selected: seq = x. SYNWhat is it? Create a synchronization sequence number when linking. When SYN = 1 and ACK = 0 at the same time, it indicates that this is the packet segment of the connection request. If the oth

Android about HTTPS SSL handshake aborted problem LookupDocument the location process and problem location of this problem1, Problem Description:The project was changed to use the HTTPS protocol, and the error code was found when accessing:域名：https://sandbox.api.xxx.com错误：SSL handshake aborted: ssl=0x5ef8e720: I/O error during system call, Connection reset by peerError description: HTTPS

TCP is the Transport layer protocol in the Internet, using three-time handshake protocols to establish a connection. When the active party sends a SYN connection request, wait for the other person to answer syn+ack[1], and eventually perform an ACK acknowledgment on the other's syn. This method of establishing a connection prevents the wrong connection from being generated. [1] The process of the TCP three-time ha
