Main ARQ protocols
-Stop & Wait ARQ (A half duplex technique)= send & wait
-Continuous ARQ (A full duplex technique)
=can send more than 1 frame & without waiting in the receiver
ABM : asynchronous balance mode support point to point
Go-Back-N ARQ
sender will send more than 1 frame at the time (1 2 3 4). If receiver tell sender that frame #2 error, sender have to send frame 2 3 4 again.
Can send just frame in window If no respond from receiver, it have to wait(can't send more frame) but receiver doesn't have to reply every frame

Can send just frame in window If no respond from receiver, it have to wait(can't send more frame) but receiver doesn't have to reply every frame
Size of the sender window must less than 2 power n (2 power n - 1), Size of the reciever window is always 1
Data Link Protocols
- Classification: Asynchronous transmission and Synchronous transmission.
- Differ by: Message delineation (The start and end of the frame), Frame length, and Frame field structure.
