I. Analysis of the Three-way handshake protocol
First, let's look at one of the most common things in our life:
During our online shopping, we often chat with customer service like this: We asked Customer Service about something, Customer Service answered, and then we broke the network... After a while, we will log on again and receive a response from the customer service.
This interaction process completes a response three times. This process

The intermediate system to the intermediate system Is-is (intermediate system to Intermediatesystem) belongs to the Internal Gateway Protocol IGP (Interior Gateway Protocol) for internal autonomous systems. Is-is is also a link state
The rationale for this protocol is unclear, but the protocol (HTTP11NIOPROTOCOL) can improve the performance of Tomcat when high concurrency is pending.The default is http/1.1, which is the blocking type, After switching to Org.apache.coyote.http11.Http11NioProtocol, the request is processed in a non-blocking manner, which allows for a certain amount of concurrency, although, in later versions of tomcat7.0,
The previous article has introduced the composition of the Protocol. A protocol generally has the following features: protocol header + Length + Data + verification. The text format can intuitively define that carriage return and line feed are the end of the Protocol, therefore, we can omit the Data Length and add the
Label: PIM-Sm Multicast Route pi pim-DM Multicast Route IGMP MRT
PIM-DM and PIM-SM are two different modes in multicast routing ASM (any source multicast. Compared with the multicast registration mechanism of PIM-SM, the diffusion mechanism of PIM-DM is more rough.
1. The PIM-DM does not need to register the pimreg virtual interface with the kernel. But like the PIM-SM, you need to add the layer-3 interface to the MRT multicast interface. To trigger the cache_miss message after the kernel
FTP text transfer protocol and FTP text transfer protocol
I have always used AFNetworking to upload images in my development project. Recently, the boss said that I should use FTP to upload images, and there is very little information on the Internet. After all, this upload method is not used much now, it took a day to learn the FTP file transfer protocol. My per
updated. Because most users record domain names, this can reduce the impact of IP address changes.
From the machine and technology perspective, domain names are not necessary. However, the Internet is composed of machines and users. Given the great help of DNS for users, DNS has been considered an indispensable part of the TCP/IP package.
DNS Server
The ing between domain names and IP addresses is stored in the DNS server. The so-called DNS server refers to some servers (computers) that
ICMP and IGMP protocols are the basic protocols in the tcp ip protocol stack. Therefore, message control is the main task of ICMP. For IGMP, the main task is to pass the information to the router. Let's take a look at the specific explanations of the two protocols below.
Internet Control Message Protocol ICMP is used to report errors and control messages on behalf of IP addresses. The IP address uses the I

End-to-end asynchronous communication protocol:Features and formats:The characteristic of a start-stop asynchronous protocol is a character transfer, and the transmission of a character always begins with the starting bit, ending with a stopped bit, and there is no fixed time interval between the characters. Its format is shown in 3. Each character is preceded by a starting bit (low level, logical value 0), the character itself has a 5~7 bit data bits
