- 3rd Level Ideas and other Noises
-
-
- On 12 August 70, I met a BBN with representatives from BBN and MIT and
- we discussed third llevel protocol.
-
-
- Dial-up The following proposed dial-up protocol was agreed upon at the
- meeting.
-
-
- The purpose of this piece of protocol is to get a process at one site
- (hereafter the using site) in contact with the logger at the other site
- (hereafter the serving site).
-
-
- To initiate contact, the using process attaches a receive socket US and
- requests connection to socket 1 in the serving host. The using NCP thus
- sends
-
-
- 1 4 4 1
- ---------------------------------------------------
- |RTS | US | 1 | p|
- ---------------------------------------------------
- |ALL | P | space |
- -------------------------------
-
- over link 1, where US is the user's receive socket, p is the link, and
- space is some nominal spae allocation.
-
-
- The serving Host may decide to refuse contact, in which case it will
- respond with the standard CLS. If it accepts contact, however, it will
- send exactly an even 32 bit number over the connection and close the
- connection. This even 32 bit number is the name of a receive socket in
- the serving Host. This socket and the next higher numbered socket are

- reserved for contact with the user. Thus the serving NCP sends
-
-
-
- 1 4 1
- ----------------------------
- | STR | 1 | US|
- ----------------------------
-
-
- on link 1, followed by
-
-
-
- 4
- -----------
- | SS |
- -----------
-
-
-
- on link p. Note that SS must be even.
-
-
- After sending the server socket number, SS, the NCP sends
-
-
-
- 1 4 4
- -------------------------------------
- |CLS | 1 | US |
- -------------------------------------
- |STR | SS+1 | US |
- ------------------------------------------
- |RTS | SS | US+1 | q |
- ------------------------------------------
- |ALL | q | space |
- -----------------------------

-
-
- The using Host also sets up these connections by sending
-
-
- 1 4 4
- ----------------------------------------
- | CLS | US | 1 |
- ----------------------------------------
- | STR | US+1 | SS |
- --------------------------------------------
- | RTS | US | SS+1 | r |
- --------------------------------------------
-
-
- At this point the user should be connected to the logger at the serving
- site.
-
- Standard Console
-
- We next agreed on an initial network standard console: 7-bit ASCII
- in 8 bit fields with the eight bit on, transmitted in contiguous
- streams. The speific codes are listed in appendix H of the IMP
- Operations manual, BBN report #1877. This seems to work only some
- hardship on PDP-10's and be fine for all others.
-
-
- For break or interrupt many systems use one of the standard
- characters; for those which need another kind of signal,
-
-
- 1 1
- ------------
- |INR | r |
- ------------
-
-
- sent over the control link should suffice.
