title: Can I dynamically modify link characteristics during a Mininet emulation?
body: <p>I am currently emulating a simple network on Mininet using the Python API available, with help from several internet tutorials and other sources. Current network emulations in Mininet support link modifications only using the <em>configLinkStatus()</em> method under the class <em>Mininet</em>.<br>
  This permits only 2 states:- <em>up</em> and <em>down</em><br>
  Other characteristics like propagation delay, bandwidth, and bit error rate can only be set during the addition of a link.<br>
  My problem contains switches and hosts in motion, which in turn causes dynamic changes in the link state. Is there a solution in Mininet to modify the links to fit my requirements?</p>
