Other Benefits of CoNDIS WAN (NDIS 5.1)
Note NDIS 5. x has been deprecated and is superseded by NDIS 6. x. For new NDIS driver development, see Network Drivers Starting with Windows Vista. For information about porting NDIS 5. x drivers to NDIS 6. x, see Porting NDIS 5.x Drivers to NDIS 6.0.
In addition to flexibility and simplicity, the CoNDIS WAN model provides the following benefits:
CoNDIS WAN miniport drivers support multipacket send and receive operations. For more information, see Sending and Receiving Data.
When a CoNDIS miniport driver indicates a receive packet, a bound protocol can defer processing of the packet. When an NDIS WAN miniport driver indicates a receive packet, a bound protocol must copy the data immediately.
CoNDIS WAN supports multipoint calls. For more information about making multipoint calls, see Making a Call.
CoNDIS WAN supports quality of service (QoS). CoNDIS WAN drivers use the NDIS_PACKET packet descriptor instead of the NDIS_WAN_PACKET packet descriptor used by NDIS WAN miniport drivers. NDIS_WAN_PACKET does not contain any QoS information. For more information about CoNDIS QoS, see Client-Initiated Request to Change Call Parameters.
Only CoNDIS WAN will support future NDIS enhancements that apply to WAN drivers.
