Easier-to-Write Filter Drivers

  • Article

NDIS 6.0 filter drivers are easier to write than the previous NDIS filter intermediate drivers.

When compared to filter intermediate drivers, filter drivers provide the following implementation advantages:

  • Filter drivers do not include a complete miniport driver interface and a complete protocol driver interfaces.

  • Filter drivers do not create and manage a virtual device. There is no virtual miniport in a filter driver.

  • If a filter driver filters specific services, the driver can bypass other services. The driver does not require code for services that are bypassed. For example, if a filter driver filters OID requests but does not filter send and receive operations, the filter driver does not require send and receive entry points.
