  PCC Done
• Number of known PCEs Done, Number of discovered
  PCEs Done.
• Set of known PCEs Done pcedpPccDiscTable
• IPv4 and IPv6 adresses (PCE-ADDRESS) Done
• Time since the PCE was discovered and any change
  to the discovered information Done

  longer be reported

  Done? pccPcedpDiscMechanism local
• TODO pcedpPccPceActivityObjects
• Provide the average and maximum rates of arrival,
  departure and modification of PCE discovery to
  enable effective analysis of the operation of the
  protocols.
