                    LINK NUMBER ASSIGNMENTS

 Today Steve Crocker asked me to announce that from now on link

numbers 2-71 (decimal), inclusive, are to be valid for use in connections. Accordingly, the Host-Host Protocol Document, which I am currently writing, will contain the following "declarative specification".

 Links are assigned as follows:

 Link Number         Assignment

 0                   Control link
 2-71                Available for connections
 1, 72-190           Reserved-not for current use
 191                 To be used only for measurement
                     work under the direction of the
                     Network Measurement Center at UCLA
 192-255             Available for private experimental use
