CONTROL_SERVICE structure (qossp.h)

The CONTROL_SERVICE structure contains supported RSVP service types.

Syntax

typedef struct _CONTROL_SERVICE {
  ULONG             Length;
  SERVICETYPE       Service;
  AD_GENERAL_PARAMS Overrides;
  union {
    AD_GUARANTEED Guaranteed;
    PARAM_BUFFER  ParamBuffer[1];
  };
} CONTROL_SERVICE, *LPCONTROL_SERVICE;

Members

Length

Length of the entire structure, in bytes.

Service

The supported service type. Must be one of the following:

Value	Meaning
SERVICETYPE_NOTRAFFIC	No data is being sent in this direction.
SERVICETYPE_BESTEFFORT	Best Effort service.
SERVICETYPE_CONTROLLEDLOAD	Controlled Load service.
SERVICETYPE_GUARANTEED	Guaranteed service.
SERVICETYPE_NETWORK_UNAVAILABLE	This service type is used to notify the user that the network is unavailable.
SERVICETYPE_GENERAL_INFORMATION	This service type corresponds to General Parameters, as defined by IntServ (the Integrated Services Working Group in the IETF).
SERVICETYPE_NOCHANGE	This specifies that the flow specification contains no changes from the previous specification.
SERVICETYPE_NONCONFORMING	Specifies non-conforming traffic.
SERVICETYPE_NETWORK_CONTROL	Specifies network control traffic.
SERVICETYPE_QUALITATIVE	Qualitative service.

Overrides

Specifies overrides to service specifications, expressed in the form of an AD_GENERAL_PARAMS structure.

Guaranteed

Specifies guaranteed service, and provides service parameters in the form of an AD_GUARANTEED structure.

ParamBuffer[1]

Describes the buffer used, in the form of a PARAM_BUFFER structure.

Remarks

The Length value can be added to the pointer to the structure to obtain the pointer to the next CONTROL_SERVICE structure in the list, until the NumberOfServices member of the RSVP_ADSPEC structure is exhausted.
