Proposed Standard Socket Numbers

I propose that there be a czar (me ?) who hands out official socket

numbers for use by standard protocols. This czar should also keep track

of and publish a list of those socket numbers where host specific

services can be obtained. I further suggest that the initial allocation

be as follows:

Sockets Assignment

0-63 Network wide standard functions

64-127 Host specific functions

128-239 Reserved for future use

240-255 Any experimental function

and within the network wide standard functions the following particular

assignment be made:

Socket Assignment

1 Telnet

3 File Transfer

5 Remote Job Entry

7 Echo

9 Discard

these socket numbers (decimal) are to be used for the socket called "L"

in the official Initial Connection protocol (ICP) as specified in NIC

7104 the "Current Network Protocols" notebook.
