Emulating wide area network delays

This is the simplest example, it just adds a fixed amount of delay to all packets going out of the local Ethernet.

# tc qdisc add dev eth0 root netem delay 100ms
Now a simple ping test to host on the local network should show an increase of 100 milliseconds. The delay is limited by the clock resolution of the kernel (Hz). On most 2.4 systems, the system clock runs at 100 Hz which allows delays in increments of 10 ms. On 2.6, the value is a configuration parameter from 1000 to 100 Hz.

Later examples just change parameters without reloading the qdisc

Real wide area networks show variability so it is possible to add random variation.

# Example YAML configuration for the adapter pattern.

# It defines a main application container which writes
# the current date and system usage information to a log file 
# every five seconds.

# The adapter container reads what the application has written and
# reformats it into a structure that a hypothetical monitoring 
# service requires.

-Xlog Usage: -Xlog[:[selections][:[output][:[decorators][:output-options]]]]
	 where 'selections' are combinations of tags and levels of the form tag1[+tag2...][*][=level][,...]
	 NOTE: Unless wildcard (*) is specified, only log messages tagged with exactly the tags specified will be matched.

Available log levels:
 off, trace, debug, info, warning, error

Available log decorators: 
 time (t), utctime (utc), uptime (u), timemillis (tm), uptimemillis (um), timenanos (tn), uptimenanos (un), hostname (hn), pid (p), tid (ti), level (l), tags (tg)
 Decorators can also be specified as 'none' for no decoration.
