DOCSIS 3.0 Operations Support System Interface Specification CM-SP-OSSIv3.0-C01-171207. Contains the relative priority assigned to this service flow. Contains the maximum rate int bits/sec assigned to this service flow. Contains the maximum burst in bytes assigned to this service flow. Contains the minimum reserved rate in bits/second assigned to this service flow. The value of the assumed minimum packet size in bytes for which the ServiceMinReservedRate will be provided. . The value of the IP Type of Service (DSCP) Overwrite assigned to this service flow. This is encoded as hexBinary in 2 bytes. The first byte is encoding the tos-and-mask, the second byte is encoding the tos-or-mask. Contains value of the Peak Traffic Rate in bits/sec assigned to this Service Flow. Contains value of the Type of Service assigned to this Service Flow. Reserved Undefined Best Effort Non-Real-Time Polling Service Real-Time Polling Service Unsolicited Grant Service with Activity Detection Unsolicited Grant Service Contains the value of the Nominal Polling Interval in microseconds assigned to this service flow. Contains the value of the Tolerated Polling Interval in microseconds assigned to this service flow. Contains the value of the Unsolicated Grant Size in bytes assigned to this service flow. Contains the Nominal Grant Interval in microseconds assigned to this service flow. Contains the value of the Tolerated Grant Jitter in microseconds assigned to this service flow. Contains the value of Grants Per Interval as integer (0-127) assigned to this service flow. Contains classifiers assigned to this service flow. Each classifier is encoded in hexBinary according to the TLV encoding. When multiple classifiers exist for the same service flow then they are encoded as the concatenated sequence of encodings of each classifier.
