                      LINK NUMBER ASSIGNMENTS

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
