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.
