Unlike almost all of the other software discussed, HTB is a newer queuing discipline and your distribution may not have all of the tools and capability you need to use HTB. The kernel must support HTB; kernel version and later support it in the stock distribution, although earlier kernel versions require patching. Let's consider the simplest scenario. The primary egress queuing discipline on any device is known as the root qdisc. The root qdisc will contain one class (complex scenarios could have multiple classes attached to the root qdisc). This single HTB class will be set with two parameters, a rate and a ceil. These values should be the same for the top-level class, and will . · More details about this can be found in the HTB Linux queuing discipline manual. Therefore the tree actually looks like this: Therefore the tree actually looks like this: 1: root qdisc (class htb) () / | \ / | \ / | \ parent qdiscs (class htb) (30) (10) (60) || || || pfifo qdiscs (queue length: txqueuelen (default, can be changed by tc utitlity)).
We use the Linux based Queuing Discipline (QDISC) and Hierarchal Token Bucket (HTB) [55], [56] to emulate the network traffic speeds and latencies on the client devices. Container migrations. More details about this can be found in the HTB Linux queuing discipline manual. Therefore the tree actually looks like this: Therefore the tree actually looks like this: 1: root qdisc (class htb) () / | \ / | \ / | \ parent qdiscs (class htb) (30) (10) (60) || || || pfifo qdiscs (queue length: txqueuelen (default, can be changed by tc utitlity)).
