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
• 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 SNA processor, or other LAN gateway.
