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

on link 1, followed by

| SS |

on link p. Note that SS must be even.

After sending the server socket number, SS, the NCP sends
