2002-03-05 2002-04-09 The namespace is a two-level hierarchy: <service_name>.<parameter_name>. Each of these elements is a integer numerical quantity. 2-127 RFC Required 128-254 Experimental use Service and Data Element Naming <Service Name> is an integer in the range 1 to 254. The number space is broken into three regions. 2-254 will be allocated to individual QoS control services. 0 (Unused to allow the direct mapping of parameter names to MIB object names) 1 Generic 2 Guaranteed service 3-4 Unassigned 5 Controlled-load service 6-127 Unassigned 128-254 Experimental or private services 255 Reserved for future expansion 1-127 Parameters defined in 128-254 Parameters defined by author of service specification document (Service and Data Element Naming) <Parameter_name> is a number in the range 1 to 254, allocated on a per-service basis. 0 (Unused to allow the direct mapping of parameter names to MIB object names) 1 NON-IS_HOP flag (local) 2 NON-IS_HOP flag (composed) 3 NUMBER_OF_IS_HOPS (local) 4 NUMBER_OF_IS_HOPS (composed) 5 AVAILABLE_PATH_BANDWIDTH (local) 6 AVAILABLE_PATH_BANDWIDTH (composed) 7 MINIMUM_PATH_LATENCY (local) 8 MINIMUM_PATH_LATENCY (composed) 9 PATH_MTU (local) 10 PATH_MTU (composed) 11-125 Reserved for assignment to parameters with a common, shared meaning across all services 126 Compression Hint 127 TOKEN_BUCKET_TSPEC 128-254 Unassigned 255 Reserved for future expansion IETF Review Hints are represented by a 32 bit field, with the high order 16 bits being the IP-compression-protocol number as defined in and . The low order 16 bits are a sub-option for the cases where the IP-compression-protocol number alone is not sufficient for int-serv purposes. 0x002d0000 Van Jacobson Compressed TCP/IP 0x00610000 IP Header Compression 0x00610100 RTP Header Compression 0x0003pppp ROHC profile 0xpppp
