RFC Number : 349 Title : Proposed Standard Socket Numbers. Network Working Group Jon Postel Request for Comments : 349 Computer Science UCLA-NMC NIC : 10428 30 May 72 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.
