4. Miscellaneous Notes
Thankfully, tcng does away with one of the minor
annoyances of tc. The following table maps the syntax
and convention of these tools with English equivalents.
Table 1. Speed/Rate syntax: tcng vs. tc
tcng | English | tc |
---|
bps | bit(s) per second | bit |
Bps | byte(s) per second | bps (argh!) |
kbps | kilobit(s) per second | kbit |
kBps | kilobyte(s) per second | kbps |
Mbps | megabit(s) per second | mbit or Mbit |
MBps | megabyte(s) per second | mbps or Mbps |
pps | packet per second | ?? |
Note that this means a slight adjustment for longtime users of
tc, but a much better choice for intuitive usablity for
English speakers.
For example, we can use conventional expressions of rate in
tcng configurations: 100Mbps,
128kbps, and even 2Gpps.
See also the tcng manual
on units.
In order for traffic control to be effective, it is important to
understand where the bottlenecks are. In most cases, you'll want to
perform the traffic control at or near the bottleneck.
