- 1. Changes to BBN Memo No. 1822 (underlined)
- As informally communicated by Dave Wa
-
- p. 11 "The IMP program can handle up to 63 active transmit links
- and 63 active receive links at a time. If the Host attempts to
- send a message on a new link when 63 active transmit links already
- exist, a "Link Table Full" message will be sent from the IMP to
- the Host, and the message will be discarded."
-
- p. 11 "1. Any link that is not used for a period of 26 seconds
- will have its entry automatically deleted by the IMP program."
-
-
-
- [Cerf: How about deleting only if the transmit link table is full?
-
- Crocker: No, because there is no other way for links to be deleted
- so they would always tend to accumulate. Furthermore,
- the table at one site may be full while another site may
- not be.]
-
- p. 13 "5 Regular with discard."
-
- This allows IMP systems to generate traffic which never actually
- reaches any Hosts since it will be discarded when it reaches the
- top of the IMP-HOST queue in the destination Host's IMP. The
- Network Measurement Center will make use of this feature.
-
- p. 13 Message type 6 is no longer assigned, and message type 10
- is really in octal so is actually type 8. Types 9-15 are unassigned.
-
- p. 17 Type 10 is really type 8.
-
- 2. Revisions to NWG/RFC 11
-
- This memo has been obsoleted by developments at UCLA and
- discussions with other nodes. NWG/RFC 22 contains some of the
- major changes. An updated version of NWG/RFC 11 is forthcoming.
-
- 3. George Gregg of UCSB will publish NWG/RFC 23 concerning the
- transmission of multiple control messages over control links.
