DLPI Primitives

Local Management Primitives

connection-less data link service.

DL_HP_RAWDLS

raw-mode service.

DL_ACLDLS

acknowledged connectionless data link service.

Since ATM is a connection-oriented link, the value of this field will always be DL_CODLS.

dl_qos_length

length, in bytes, of the negotiated/selected values of the quality of service (QOS) parameters. The returned values are those agreed during the negotiation. If QOS has not yet been negotiated, default values will be returned; these values correspond to those that will be applied by the DLS provider on a connect request.

The QOS values are conveyed in the structures defined in the above sections in this chapter. For any parameter the DLS provider does not support or cannot determine, the corresponding entry will be set to

DL_UNKNOWN.

dl_qos_offset

offset from the beginning of the M_PCPROTO block where the current QOS parameters begin.

dl_qos_range_length

length, in bytes, of the available range of QOS parameter values supported by the DLS provider. This the range available to the calling DLS user in a connect request. The range of available QOS values is conveyed in the structures defined in the following section in this chapter. For any parameter the DLS provider does not support or cannot determine, the corresponding entry will be set to

DL_UNKNOWN.

dl_qos_range_offset

offset from the beginning of the M_PCPROTO block where the available range of quality of service parameters begins.
