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
oclearcase/" target="_blank" >ccurs. 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.
