QOS_DIFFSERV structure (qosobjs.h)

  • Article

The QOS_DIFFSERV traffic control object is used to specify filters for the packet scheduler when it operates in Differentiated Services Mode.

Syntax

typedef struct _QOS_DIFFSERV {
  QOS_OBJECT_HDR ObjectHdr;
  ULONG          DSFieldCount;
  UCHAR          DiffservRule[1];
} QOS_DIFFSERV, *LPQOS_DIFFSERV;

Members

ObjectHdr

The QOS object QOS_OBJECT_HDR. The object type for this traffic control object should be QOS_OBJECT_DIFFSERV.

DSFieldCount

Number of Diffserv Rules in this object.

DiffservRule[1]

Array of QOS_DIFFSERV_RULE structures.

Remarks

The QOS_DIFFSERV object is used to specify the set of Diffserv rules that apply to the specified flow, all of which are specified in the DiffservRule member. Each Diffserv rule has an InboundDSField value, which signifies the DSCP on the Inbound packet. The Diffserv Rules also have OutboundDSCP and UserPriority values for conforming and nonconforming packets. These indicate the DSCP and 802.1p values that go out on the forwarded packet. Note that the DSCP or UserPriority mapping based on ServiceType or QOS_DS_CLASS or QOS_TRAFFIC_CLASS is not used in this mode.
