public class DiffServPacketClassifier

extends java.lang.Object

This class (DiffServPacketClassifier) is used to define the DiffServ packet flows coming into a router with DiffServ packet processing capability. Each DiffServ packet flow individually may contain multiple micro-flows of different class-types.

  Currently, a DiffServFlow may contain following DiffServ class-types:
	- NCT1, NCT0 (network control traffic) 
	- EF (expedited forwarding)
	- AF4, AF3, AF2, AF1 (assured forwarding)
	- BF (best-effort forwarding)

   The router with DiffServ packet processing capability maintains
   only one DiffServTrafficConditioner instance which maintains
   only one DiffServPacketClassifier instance.
   DiffServPacketClassifier maintains a DiffServFlowTable of the 
   information of each DiffServ packet flow.
