Categories : Socket Numbers References : RFC's 322, 204

                  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.
