Becomes C811 Data Link Provider Interface (DLPI) Version 2 11/99

Description: This Data Link Provider Interface (DLPI) specification defines a STREAMS kernel-level instantiation of the ISO Data Link Service Definition DIS 8886 and Logical Link Control DIS 8802/2 (LLC). Where the two standards do not conform, DIS 8886 prevails. This enables a data link service user to access and use any of a variety of conforming data link service providers without special knowledge of the provider's protocol. Specifically, the interface is intended to support X.25 LAPB, BX.25 level 2, SDL C, ISDN LAPD, Ethernet, CSMA/CD, FDDI, token ring, token bus, Bisync, Frame Relay, ATM, Fiber Channel and HIPPI. This list will be augmented with time. Among the expected data link service users are implementations of the OSI network layer and SNA path control.
