public class DiffServFlow

extends java.lang.Object

DiffServFlow is used to describe the aggregated packet flows of (multiple) DiffServ class-type(s).

DiffServFlow maintains the DiffServCTFlowTable that contains the 
 information of each class-type micro-flow.
 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 informations of the packet processing for a specific DiffServFlow
   are defined in the DiffServFlowProfile and DiffServPrfFlowProfile.
	a. DiffServFlowProfile:
	  - scheduler to define the DiffServPacketScheduler
	  - PrfFlowProfileTable to contain DiffServPrfFlowProfiles
	  - definition of meter monitoring
	  - definition of queue monitoring
	b. DiffServPrfFlowProfile:
	  - class-type
	  - priority
	  - weight
	  - meter
	  - bitrate (CIR for meter)
	  - Queue
	  - SchedulingRate
   Each DiffServFlow object contains at least one DiffServCTFlow
   entry in the DiffServCTFlowTable(Vector).
   The DiffServCTFlow contains the DiffServ packet flow mapping
   informations, such as source/destination address range, 
   protocol number, source/destination port range, and ToS. 
	a.DiffServCTFlow
	   - srcIPAddressList, srcIDList
	   - destIPAddressList, destIDList
	   - ProtocolNum
	   - ToS (Type of Service)
	   - SrcPortMin, SrcPortMax: source port range 
	   - DestPortMin, DestPortMax: destination port range 
	   - class-type
	   - DiffServPrfFlowProfile DSFProfile
