Burst for each TCP connection

This is little how-to create manual burst using queue tree.
As it is bandwidth control using queue tree first we need to mangle traffic
first i mangle all connections, then i mark first 2Mbytes then i mark the rest of packets

/ip firewall mangle add chain=forward protocol=tcp action=mark-connection new-connection-mark=new_conn passthrough=yes comment="mark all new connections" disabled=no
/ip firewall mangle add chain=forward protocol=tcp connection-mark=new_conn connection-bytes=0-2000000 action=mark-packet new-packet-mark=new_packet passthrough=no comment="mark packets" disabled=no
/ip firewall mangle add chain=forward protocol=tcp connection-mark=new_conn action=mark-packet new-packet-mark=old_packets passthrough=no comment="marking old packets" disabled=no


now, when packets has been marked i need queue types that allows me limit traffic per-user basis, so i have to create 2 queue types.


/queue type add name="PCQ_Upload" kind=pcq pcq-rate=0 pcq-limit=50 pcq-classifier=src-address pcq-total-limit=2000
/queue type add name="PCQ_Download" kind=pcq pcq-rate=0 pcq-limit=50 pcq-classifier=dst-address pcq-total-limit=2000


now i have to limit all the rates using queue tree, i will limit it that way - that first 2Mbits (as in mangle) will have higher priority over rest of traffic where connection bytes exceed 2Mbits.

i assume that connection that is available have 5Mbits full-duplex

/queue tree add name="Main_Upload" parent=Public packet-mark="" limit-at=0 queue=default priority=8 max-limit=5000000 burst-limit=0 burst-threshold=0 burst-time=0s disabled=no

/ queue tree add name="Up First 2Mbyte" parent=Main_Upload packet-mark=new_packet limit-at=4000000 queue=PCQ_Upload priority=1 max-limit=5000000 burst-limit=0 burst-threshold=0 burst-time=0s disabled=no

/ queue tree add name="Up Rest Mbytes" parent=Main_Upload packet-mark=old_packets limit-at=1000000 queue=PCQ_Upload priority=8 max-limit=5000000 burst-limit=0 burst-threshold=0 burst-time=0s disabled=no

/ queue tree add name="Main_Download" parent=Local packet-mark="" limit-at=0 queue=default priority=8 max-limit=5000000 burst-limit=0 burst-threshold=0 burst-time=0s disabled=no

/ queue tree add name="Down First 2Mbyte" parent=Main_Download packet-mark=new_packet limit-at=4000000 queue=PCQ_Download priority=1 max-limit=5000000 burst-limit=0 burst-threshold=0 burst-time=0s disabled=no

/ queue tree add name="Down Rest Mbytes" parent=Main_Download packet-mark=old_packets limit-at=1000000 queue=PCQ_Download priority=8 max-limit=5000000 burst-limit=0 burst-threshold=0 burst-time=0s disabled=no
