NDIS Support in Windows Embedded CE (Windows Embedded CE 6.0)
1/6/2010
Windows Embedded CE supports NDIS 5.1 and includes technologies that improve support for network driver development.
The following table shows the various NDIS technologies available in Windows Embedded CE.
| Option | Description |
|---|---|
Packet send cancellation |
New APIs for NDIS protocols allow pending packets to be cancelled. The APIs introduce an additional handler that notifies NDIS miniport drivers of packet cancellations. |
Hardware offloading |
Object identifiers that handle TCP/IP transport task offloading to a network interface card (NIC). |
Wireless WAN Support |
Object identifiers that support wireless WAN miniport drivers. |
Signal strength |
Object identifiers that request the signal strength in decibels that the miniport driver's NIC receives. The object identifiers also set a signal strength threshold. |
64-bit counters |
Larger 64-bit statistical counters that provide sustained high-speed throughput. |
Media Sense |
An interface that monitors media state. |
Wake on LAN |
Object identifiers that define a wakeup packet to the NIC hardware. |
Deserialize miniport |
The ability for miniport drivers to handle synchronization internally. |
Packet stacking |
Access to packet descriptors in a stack of layered NDIS drivers improves performance. Earlier versions of NDIS required intermediate drivers to allocate a new NDIS_PACKET to encapsulate send and receive data that they passed to other layers. |
Machine name notification |
NDIS can now pass the computer name to the miniport driver. |
Power management |
Object identifiers that support power management. |
Note
The S-List based functions (such as NdisInitializeSListHead, NdisInterlockedPushEntrySList, NdisInterlockedPopEntrySList, and NdisQueryDepthSList) are not supported in Windows Embedded CE.
