          Appeal No. 1997-0809                                                        
          Application 08/033,599                                                      

               This is a decision on appeal under 35 U.S.C.  134 from                
          the Examiner's refusal to allow of claims 1, 3-9, 12, and                   
          13.  The rejection of claims 10 and 11 has been withdrawn                   
          (Examiner's Answer, page 2) and presumably these claims                     
          stand objected to.                                                          
               We affirm-in-part.                                                     
                                    BACKGROUND                                        
               The disclosed invention is directed to the management                  
          of packet transmission networks.                                            
               Claim 9 is reproduced below.                                           
                    9.  A network management system for a packet                      
               communications network having a plurality of packet                    
               switching nodes connected by a plurality of data links                 
               represented by virtual circuit segments comprising                     
                    means for generating management information in                    
               frames suitable for transmission on the packet                         
               communications network,                                                
                    said frames comprising major vectors associated                   
               with particular types of management information and                    
               including a plurality of subvectors containing specific                
               information about the status and configuration of                      
               virtual circuit segments, and                                          
                    means responsive to said management information                   
               for managing said packet communications network.                       

               The Examiner relies on the following prior art patents:
