For example, instead of having 100 queues with 1000kbps limitation for download, we can have one PCQ queue with 100 sub-streams

PCQ has burst implementation identical to Simple Queues and Queue Tree:

• pcq-burst-rate (number) : maximal upload/download data rate which can be reached while the burst for substream is allowed
• pcq-burst-threshold (number) : this is the value of burst on/off switch
• pcq-burst-time (time) : a period of time (in seconds) over which the average data rate is calculated. (This is NOT the time of actual burst)

PCQ also allows using different size IPv4 and IPv6 networks as sub-stream identifiers. Before it was locked to a single IP address. This is done mainly for IPv6 as customers from an ISP point of view will be represented by /64 network, but devices in customers network will be /128. PCQ can be used for both of these scenarios and more. PCQ parameters:

• pcq-dst-address-mask (number) : the size of IPv4 network that will be used as a dst-address sub-stream identifier
• pcq-src-address-mask (number) : the size of IPv4 network that will be used as an src-address sub-stream identifier
• pcq-dst-address6-mask (number) : the size of IPV6 network that will be used as a dst-address sub-stream identifier
• pcq-src-address6-mask (number) : the size of IPV6 network that will be used as an src-address sub-stream identifier

Interface Queue

/queue interface

Before sending data over an interface, it is processed by the queue. This sub-menu lists all available interfaces in RouterOS and allows to change queue type for a particular interface. The list is generated automatically.
