DLSw (Data-Link Switching)

Is a protocol designed to tunnel non-IP based protocols such as IBM Systems Network Architecture (SNA) and NetBIOS over an IP network.

DLSw was initially documented in IETF RFC 1434 in 1993. In 1995 it was further documented in IETF RFC 1795.

DSLw version 2 was presented in 1997 in IETF RFC 2166 as improvement to RFC 1795.

DSLw+ is IETF RFC 1795 compliant but with some proprietary extensions by Cisco.
