What feature does ip service not have?
ip service does not have the "QoS guarantee" feature.
The services provided by IP have the following three characteristics: unreliable data delivery service, connectionless-oriented transmission service, and best-effort delivery service.
Related introduction:
IP (Internet Protocol) protocol, also known as Internet Protocol, is responsible for communication between networks on the Internet and specifies the transmission of data from one network to another. The rules that should be followed are the core of the TCP/IP protocol. The Internet seems to be real, but in fact it is a virtual network that does not exist. It just uses the IP protocol to connect all the computer LANs in the world that are willing to access the Internet, so that they can all communicate with each other. communication. Just as humans need to use the same language to communicate effectively, communication between computers also needs to use the same "language", and the IP protocol is exactly this language.
The IP protocol has the flexibility to adapt to diverse network hardware. As long as any network can transmit binary data from one location to another, it can use the IP protocol to join the Internet. But every computer connected to the Internet must also comply with the IP protocol if it wants to communicate and communicate.
The IP protocol is point-to-point. The protocol is simple, but the reliability of the transmission cannot be guaranteed. It uses a connectionless datagram mechanism and "best effort delivery" of the data. It does not verify whether it is correct or not, nor does it guarantee Grouping order, no confirmation is sent. Therefore, the IP protocol provides unreliable, connectionless datagram transmission between hosts.
