* What is WFQ ? Where I can read more about this scheduling policy ?
--------------------------------------------------------------------
  A.K. Parekh and R.G.Gallager. "A generalized processor sharing approach 
  to flow control in integrated services networks: the single node case".
  IEEE/ACM Transactions on Networking, 1(3):344-357, Jun 1993

  S. Vegesna. "IP Quality of Service". Cisco Press, 1st edition, 2001 


* What each source file is responsible for ?
--------------------------------------------------------------------
  wfq.cc           - main file
  wfqclassifier.cc - abstract classifier that help WFQ to determine the 
                     right class of a packet (may disapper in the future)
  wfqaggreg.cc     - the classifier that selects a packet based on a
                     value of its FID (flow ID)


* Does implementation of WFQ change something in the NS-2 simulator ?
---------------------------------------------------------------------
  Yes and no. Of course, it changes Makefile.in so that new source files
  are compiled and included into the binary. But from the conceptual point
  of view, everything remains the same.
