Cisco leads the industry in providing integrated switching solutions for Token Ring networks. Whether you plan to stay with Token Ring or migrate to Ethernet, the smart choice is a Cisco switched network. With high-speed support for native Token Ring frames over Inter-Switch Link (ISL), Asynchronous Transfer Mode (ATM), or Fast/Gigabit Ethernet, a single backbone can provide transport of both Ethernet and Token Ring virtual LANs (VLANs). In addition, Cisco IOS® software provides inter-VLAN routing and bridging, including Token Ring-to-Ethernet conversion. With Cisco's switching solutions, Token Ring customers no longer have to worry about the future.
Source-Route Translational Bridging (SR/TLB)
source-route translational bridging. Method of bridging where source-route stations can communicate with transparent bridge stations with the help of an intermediate bridge that translates between the two bridge protocols.

Source-Route Transparent (SRT) Bridging
source-route bridging. Method of bridging originated by IBM and popular in Token Ring networks. In an SRB network, the entire route to a destination is predetermined, in real time, prior to the sending of data to the destination.
