This article lists some of the features of Network Driver Interface Specification (NDIS) in Windows 2000.

Some of the major features in NDIS in Windows 2000 include:

•	Support for Plug and Play, Power Management, and Windows Management Instrumentation(WMI)
•	Support for connection-oriented media such as asynchronous transfer mode (ATM).
•	Integrated Miniport Call Managers (MCM) support that controls network adapters with on-board connection-oriented protocol signaling capabilities.
•	The ability to offload tasks from the TCP/IP transport to the network adapter (for example, TCP/IP checksum tasks, IP Security tasks, and the segmentation of large TCP packets).
•	Support for older (legacy) transport stacks over connection-oriented media (for example, the LAN Emulation (LANE) driver and User Network Interface (UNI) Call Manager).
•	Support for serialized and deserialized NDIS miniport drivers. For more information about deserialized miniport drivers, click the following article number to view the article in the Microsoft Knowledge Base: 217305 (http://support.microsoft.com/kb/217305/) Full duplex support with Windows NT
•	Telephonic services over ATM and other connection-oriented media.
•	802.1p packet priority support. For more information about 802.1p, click the following article number to view the article in the Microsoft Knowledge Base: 222020 (http://support.microsoft.com/kb/222020/) Description of 802.1P signaling
•	Support for forwarding packets from one adapter port to another on the same network adapter, or on a similar network adapter, without routing the packets through the host processor.
