Pipelining
- Go back in
- Local waits for an eventual response from server containing an adjusted window size, and adjusts to it
- If local receives a timeout, local attempts resending the packets
- Timer is based upon oldest packet sent
- If server receives an out of sequence packet, it won't be buffered
- This is because the server knows local will send all of the packets again
- Ideal for channels with large, chunked packet losses
- Selective repeat
- Data is still sent off, and a response is waited for for a packet
- When there's a timeout on a packet response, only that one packet is resent
- Ideal for channels with small, individual losses
- Window size must be less than or equal to half the size of seq# space
