data-link switching
Interoperability standard, described in RFC 1434, that provides a method for
forwarding SNA and NetBIOS traffic over TCP/IP networks using data link layer
switching and encapsulation. DLSw uses SSP (Switch-to-Switch Protocol) instead
of SRB, eliminating the major limitations of SRB, including hop-count limits,
broadcast and unnecessary traffic, timeouts, lack of flow control, and lack of
prioritization schemes. See also DLSw+, SRB, and SSP
(Switch-to-Switch Protocol).
