Subject: Single DLSw Switch

Thank you Peter, Shannon and Wayne for your prompt responses to my query.

My simple (hopefully, not simplistic) take on a single DLSw switch is:

	1) It provides a switch between two SDLC connections into the 
	same router box.
	2) The advantages provided by paired DLSw connections across a WAN: 
		a) hop count reset
		b) local acknowledgement (reduced sensitivity to time out)
		c) direct delivery of NetBIOS broadcast packets (firewall)
		d) Segmentation of large bridges separated by a WAN

	may be applied to a large bridged LAN environment, effectively taking 
	advantage of DLSw features needed for the WAN environment.

Thanks again,
Dan Profant

Dan, I believe you could generalize the first statement to:
	" ... a switch between two DLC (not just SDLC) connections."

     We should remember to consider this single node DLSw connection when
     addressing management issues.
