- Reallocation in Case of Input Error
-
-
- In case of reading a message from the IMP, it may be impossible for the
- receiving NCP to determine the length of the message if an input error
- occurs. The following protocol will be used at the CCN-Host at UCLA to
- resynchronize flow control.
-
- If an input error is detected and the NCP can find the intended link
- number, it will send a GVB with frac = O to the sending Host and disregard
- further incoming messages on that link. When the RET has been received, a
- new ALL will be sent.
-
- If the sending Host is not waiting for a RFNM when the GVB arrives, it will
- send the RET immediately. If it is waiting for a RFNM corresponding to the
- message with the error or a RFNM corresponding to a following message, it
- will send the RET after the RFNM has been received.
-
- In this way, the receiving Host will know that the link is clear before it
- issues a new ALL.
