DLSW is an older technology developed by IBM, originally for use with SNA
over WANs. DLSW+ is a Cisco version of DLSW that is also backwardly
compatible with DLSW and RSRB. It supports multiple encapsulations and even
handles translational bridging automatically. It's strength comes from the
fact that it terminates the LLC Type 2 connection at the switch, making the
LLC connections at each end independent of each other. This limits LLC
time-outs to the Local LAN. It also prevents LLC acknowledgments from
traversing the WAN. This greatly reduces traffic across the WAN links.
This design allows switches to apply "back pressure" to end systems to
provide flow control and congestion control.

hurled at the rich by the concrete-bound illiterates who were unable to
conceive of the source of wealth or of the motivation of those who produce
it.

Hi all,"
Could someone tell me what DLSW is and what it means? I hear it's an old
routing protocol ""data link switching "or "digital line switching "but it's
not confirmed. I can't find anything about it in my books. Could someone
clarify this for me please?
Thanks,
Mondo
