Data-Link Switching (DLSw) and Data-Link Switching Plus (DLSw+)
Data-link switching (DLSw) provides a means of transporting IBM Systems Network Architecture (SNA) and network basic input/output system (NetBIOS traffic over an IP network. It serves as an alternative to source-route bridging (SRB), a protocol for transporting SNA and NetBIOS traffic in Token Ring environments that was widely deployed prior to the introduction of DLSw. In general, DLSw addresses some of the shortcomings of SRB for certain communication requirements---particularly in WAN implementations.
Data-Link Switching Plus (DLSw+)
Data Link Switching Plus (DLSw+) is a means of transporting Systems Network Architecture (SNA) and NetBIOS traffic over a campus or wide-area network (WAN). The end systems can attach to the network over Token Ring, Ethernet, Synchronous Data Link Control (SDLC) protocol, Qualified Logical Link Control (QLLC), or Fiber Distributed Data Interface (FDDI). (FDDI is supported on the Cisco 7000 series only and requires Cisco IOS Release11.2 or later.) DLSw+ switches between diverse media and locally terminates the data links, keeping acknowledgments, keepalives, and polling off the WAN.
