Integrated SDLC Conversion

Integrated SDLC conversion enables existing SDLC trafﬁc to share a backbone

network with LAN trafﬁc without an intervening TCP/IP network. Trafﬁc enters

the DLSw router as SDLC and goes out the router as LLC2 over Token Ring or

Ethernet. The destination endstation can reside on the Token Ring or Ethernet

directly connected to that DLSw router. SRB can forward the trafﬁc through the

network to a destination host or endstation. In this network, the local router

performs the SDLC conversion, and forwards the trafﬁc across the network to the

host (Figure 1-5).

In Figure 1-5, the SDLC clients appear to both the network and the Token Ring

LAN-attached host as if they were natively LAN-attached.
