1-10 Introduction
Routing Around Obstacles
Explaining this scenario on the simplest level (using the Mesh protocol as shown in the graphic
above), A can route a packet to B, despite the tree obstruction (block of trees) within the path. How
does this procedure work?
1 A can see that there is not a clear path to B.
2 C can see that there is a clear path to B. The most efficient path in this case is to hop from
A to C to B.
Note: No manual programming is required because A automatically detects its neighboring unit/
router (in this case C, and B and detect a clear path to C). Therefore, the packet is successfully re-
routed around the obstacle (between B and A).
This process creates a more scalable, flexible, and extended wireless network (as shown in Network
Expansion: Connecting Buildings in a SPEEDLAN 9000 Network, page 1-12).
