Using Translation Bridge Services

This chapter contains:

• An overview of the transparent-to-source routing translation bridge (referred

to as the translation bridge in this chapter)

• Implementation information you should know before you use the translation

bridge

• Instructions for operating the translation bridge

• Descriptions of translation bridge parameters and instructions for editing

those parameters

Translation Bridge Overview

One type of network uses a technique called source routing (SR) to bridge frames

across networks. In SR networks, the station that transmits a frame includes, as

part of the frame, the route that frame should traverse. The station learns the route

through a route-discovery process. (See Chapter 2, “Using Source Routing Bridge

Services,” for details.)

Another type of network uses a technique called transparent bridging (TB) to link

networks. In a TB network, the bridge builds a database of node addresses to

determine when it should forward or drop frames; the end station s on TB

networks are not aware of forwarding routes. (See Chapter 1, “Using Transparent

Bridge Services,” for details.)

The translation bridge provides a method of bridging these two kinds of networks.

This allows end station s using different bridging techniques to communicate as

though they use the same bridging technique.
