Go language TCP/IP network programming At first glance, connecting two processes through the TCP/IP layer can be scary, but in the go language it may be much simpler than you think.

　　 　 Table 5. IP packages from A to B 　　 In this case, IP addresses are redundant because they do not play any role at all. IP addresses can only increase the processing time and occupy excessive transmission bandwidth. After B receives the package, the IP layer checks whether the destination address in the package

1. TCP connectionTCP (transmission Control Protocol) transmission protocol. TCP is the host-to-host layer of the Transmission Control Protocol, providing a reliable connection service, using three-time handshake confirmation to establish a connection. The bit code is the TCP flag bit, there are 6 kinds of marking: SYN (synchronous set up) ACK (acknowledgement ack

occupying these spoofed hosts in advance. This is a Smurf attack. DRDoS attacks are based on this principle. Hackers also use a special packet sending tool to first send SYN connection request packets that have forged the source address to spoofed computers. According to the three-way handshake rule of TCP, these computers send SYN + ACK or RST packets to the source IP address to respond to this request. L

1 ARP Protocol OverviewIP packets are usually sent over Ethernet, but Ethernet devices do not recognize 32-bit IP addresses. They transmit Ethernet packets at 48-bit Ethernet addresses. Therefore, the IP drive must convert the destination IP address to the destination IP address of the Ethernet network. There is a stat

, and coded layer by layer. Data is received from the bottom up and decoded layer by layer. When an application transmits data over TCP, the data is sent to the protocol stack, and then passes through each layer one by one until it is sent to the network as a string of bit streams. Each layer adds some header information (and sometimes tail information) to the received data, as shown in Step 6. The data uni

added from the top of the protocol stack to the corresponding header (and tail), and then the link layer is converted to a bitstream sent to the transmission medium, this process is called encapsulation. The process is as follows:9, sub-use: When the host receives data from the transmission media, the bitstream will be from the bottom of the protocol stack up, remove the corresponding header (and tail), an

the bit ACK -- the validation number field is valid only when ACK = 1. When ACK = 0, the confirmation number is invalid. PuSH bit PSH (PuSH): receives the packet segment of PuSH bit 1 received by TCP, and delivers it to the receiving application process as soon as possible, instead of waiting until the entire cache is filled up before delivery.
