Description
Variable that contains the maximum queue size per quality of service
class for all flows together. When a given flow has occupied its
guaranteed buffering space in the quality of service queue, it may occupy
more non-guaranteed buffering space as long as the maximum for the
quality of service flow has not been reached. The queue size is expressed
in milliseconds: for each packet inside the quality of service queue, the
time needed to transmit it via the satellite is calculated taking into account
the baudrate, the modulation and coding. High priority traffic (real-time
traffic for instance) gets usually a larger queue size than the low priority
traffic (non real-time traffic).

Description
Different QOS rules can be defined. Each rule defines a pattern to match
incoming Ethernet packets. When a packet is matched by a rule, this
packet gets the priority that is associated to this rule.
Qos rules are matched in sequence (first to last rule). There is one special
rule, being the first rule in the table: this rule gets the default classifier. The
default rule is selected if no other rule matches.
Examples:
ip.proto==udp
ip.proto==17
eth.type==lacp
ip.tos==4-255
