Understanding Bridge Topologiespoint to point, connecting just two locations together. Figure 14-1 shows a typical bridge topology for point-to-point systems. Figure 14-1. Point-to-Point Bridge Topologymultipoint systems are being installed today. In most systems, one bridge is usually defined as the central, or master, bridge. This provides the central point of data flow from the remote sites. (See Figure 14-2.) Figure 14-2. Point-to-Multipoint Bridge Topology[View full size image] ![]() Figure 14-3.

This can also permit some types of traffic filtering to improve the throughput of the wireless link. |
