                        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.
