Best Effort Traffic Profile Configuration Parameters
- Parameter
- Description
- Traffic Priority
- Priority for the service flow. Higher-priority service flows are given preference over lower-priority service flows.
- Request Transmission Policy
- The interval usage code that the cable modem uses for upstream transmission requests and packet transmissions for this service flow. It also specifies whether requests can be piggybacked with data.
- Max Sustained Traffic Rate (bps)
- The maximum sustained rate, in bits per second, at which traffic can operate over the service flow.
- Max Traffic Burst
- The maximum burst size for the service flow.
- Min Reserved Traffic Rate (bps)
- The guaranteed minimum rate, in bits per second, that is reserved for the service flow.
- Assumed Min Packet Size (bytes)
- The assumed minimum packet size, in bytes, for which the minimum reserved traffic rate is provided.
- Maximum Concatenated Bursts (bytes)
- The maximum size, in bytes, of a concatenated frame (a group of frames) that a service flow can transmit.
- Upstream Peak Traffic Rate
- A four-byte unsigned integer field that specifies the peak traffic rate, in bits per second, that is allowed for a service flow. The range is 0 – 4,294,967,295 bps (4 Gbps–1).
- Required Attribute Mask
- A 32-bit mask that specifies whether certain attributes are required in a service flow.
- Forbidden Attribute Mask
- A 32-bit mask that specifies whether certain attributes are forbidden in a service flow.
- Attribute Aggregation Rule Mask
- A 32-bit mask that controls whether groups of attributes are either required or forbidden in a service flow.
- Minimum Buffer
- The lower limit for the size, in bits, of the buffer to be provided for a service flow. The range is 0 – 4,294,967,295 bits (4 Gb–1). The default is a value of 0, which indicates that there is no lower limit.
- Target Buffer
- The value for the size, in bits, of the buffer to be provided for a service flow. The range is 0 – 4,294,967,295 bits (4 Gb–1). If the parameter is omitted or set to a value of 0, then the device selects any buffer size within the range of the minimum and maximum buffers, using a vendor-specific algorithm.
- Maximum Buffer
- The upper limit for the size of the buffer to be provided for a service flow. The range is 0 – 4,294,967,295 bits (4 Gb–1). The default is no limit.
