For example:Gethibernatetemplate ().

The sequence range that the sender cares about is the transmission sliding window, and the sequence receiving sliding window that the receiver cares about. In the automatic Resend Request protocol for N frames, the size of the send sliding window must be less than 2 ^ m (m indicates the length of the window, and the reas
