Data Link Switching Overview
1-5
DLSw Single-Switch Services
DLSw single-switch services enable the router to perform link level conversion,
while providing services to ensure session integrity. Examples of single-switch
conversions include
SDLC to Token Ring
SDLC to Frame Relay (RFC 1490)
Token Ring to Ethernet
Ethernet to bridged SNA over Frame Relay
Single switch configurations provide services to attached devices and networks to
ensure session availability, including
Local acknowledgment and termination of the LLC2 or SDLC session
802.5 routing information field (RIF) caching (allowing more than eight
source-route-bridged rings between a local and remote system)
MAC address and NetBIOS name caching
Figure 1-2 illustrates a sample network using a single Bay Networks router. The
router can communicate with an IBM front end processor (FEP) or other LAN
gateway.
