If set to true, per-hop, per-class metrics will be traced. (Trace files have then to be specified, using <TT>JoBS object trace-file filename</TT>.)

Defaults to false (drop-tail).</DD><DT><STRONG>adc_resolution_type_</STRONG></DT><DD>Can be 0 or 1. If set to 0, traffic will be dropped from classes that have an ADC if the ADC cannot be met by adjusting the service rates. If set to 1, traffic will be dropped from all classes. A resolution mode set to 1 is therefore fairer, in the sense that the pain is shared by all classes, but can lead to more deadline violations. Defaults to 0.</DD><DT><STRONG>shared_buffer_</STRONG></DT><DD>Can be 0 or 1. If set to 0, all classes use a separate per-class buffer (which is required if only rate guarantees are to provided). All per-class buffers have the same size. If set to 1, all classes share the same buffer (which is required if loss differentiationis to be provided). Defaults to 1.</DD><DT><STRONG>mean_pkt_size_</STRONG></DT><DD>Used to set the expected mean packet size of packets arriving at a JoBS link.
