7.5.4.1 JoBS objects

trace_hop_
Can be true or false. If set to true, per-hop, per-class metrics will be traced. (Trace files have then to be specified, using JoBS object trace-file filename.) Defaults to false.
drop_front_
Can be true or false. If set to true, traffic will be dropped from the front of the queue. Defaults to false (drop-tail).
adc_resolution_type_
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.
shared_buffer_
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 differentiation is to be provided). Defaults to 1.
mean_pkt_size_
Used to set the expected mean packet size of packets arriving at a JoBS link. Setting this variable is required to ensure proper delay differentiation.
