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.
