Detailed explanation-1: -Because IP provided basic packet delivery services without guarantees, it is called a best-effort delivery service. It does its best to deliver packets to the destination, but takes no steps to recover packets that are lost or misdirected.
Detailed explanation-2: -UDP is often described as connectionless or “best-effort delivery” because it does not establish a connection before sending, it does not sequence packets before sending, and it does not provide error control through retransmission.
Detailed explanation-3: -IP networks are often described as “best effort” networks. This refers to the approach to service quality where the network itself does not actively differentiate in its treatment of services that transit the network. In a best effort IP network all IP packets are treated in the same fashion.
