This object represents the committed burst size (CBS) against which associated traffic streams will be metered. The CBS specifies the maximum burst size that is supported for flows to be considered to be at a high level of conformance. Typically, this value represents the maximum number of tokens in a token bucket.

This object specifies flow data in bytes per second units such that, for example, a value of 100 equates to a committed information rate of 100 bytes per second.

Committed burst (and rate) information must be present if the qosMeterDataSpecification object has the value committedData(2) or peakRate(3). This, in turn, requires that at least both high and medium conformance actions be specified.
