In the network, IP addresses are the foundation, so the packet header format is also very important. Although the format of IPv6 headers has been standardized A long time ago, IPv6 is gradually put into use. Let's talk about the structure of IPv6 headers. IPv6 Header Format

So the RARP protocol is rarely usedRARP and RAP: Inter-network Control Message Protocol ICMPObjective:To improve the chances of successful IP datagram

The concept of TCP has been mentioned many times. Today we will introduce the TCP packet header format for this Protocol. In this article, we will give a detailed description of its organization and basic meaning, as well as the role of each part. TCP Data Header The figure shows the format of the TCP Data

IP addressUse:Such hosts are often diskless workstations. So the RARP protocol is rarely usedRARP and RAP: Inter-network Control Message Protocol ICMPObjective:To improve the chances of successful IP datagram deliveryAttention: Allow hosts and routers to report error conditions and provide reports on abnormal conditions ICMP is not a high-level protocol, but an IP layer protocol The ICMP packet acts as the data of the IP layer datagram, plus the

Introduction User Datagram Protocol is a protocol that defines the computer communication used to provide Packet Exchange in the interconnected network environment. By default, this Protocol considers the network protocol (IP) as its underlying protocol. This Protocol provides the simplest Protocol mechanism for sending information to another user program. This Protocol is operation-oriented and does not provide commit and copy protection. If the application requires reliable data transmission,

Key features of 1.TCP(1). TCP's connection-oriented Transport layer protocol;(2). Each TCP connection can have only two endpoints (endpoint), which is the connection between point to points, each endpoint is called socket (socket), Socket socket= (IP address: port number). (3). TCP provides reliable payment of services;(4). TCP provides duplex communication;(5). Byte stream oriented. header format for 2.TCP

Cookie-related HTTP headersthere are two HTTP headers and cookies about: Set-cookie and cookies. Set-cookie is sent by the server, which is included in the header of the response request. It is used to create a cookie on the clientThe cookie header is sent by the client and is included in the header of the HTTP request. Note that only the domain and path of the c

, the file will be uploaded to the server.The following is the data received by the server:Data received by the serverThis is a POST request. So the data is placed in the request body, not within the request header.This line indicates that the request is in the "Multipart/form-data" format, and that "boundary" is the string "---------------------------7db15a14291cce".It is not hard to imagine that "boundary" is used to separate data from different par

Determine if the file is in CSV format by reading the file headerBy reading the CSV file header, to determine whether the file is a CSV file type, in general, only through the file suffix to determine the type of the file, it is unreasonable, as long as the file suffix can not identify the file is not exactly the correct file format, the executable file suffix ch

Before going into the TCP connection, we need to have some knowledge about the Header Format of the TCP segment. We know that TCP segments are divided into headers and data. The data part is the text stream data actually transmitted by TCP. The following is the Header Format of the TCP segment: from wikipedia, pay atte

When we write the script, we always start to define the script header format according to the script writing specification, the time is not likely to feel the trouble is inefficient, here is to introduce a good idea to everyone.1 First we in VIM first copy the content of the head format, here to copy a two senior format
