CHAPTER 3: Network Design and Topologies 3.6 Examples of Network Designs INGLE OINT OINT The most basic of topologies is the point-to-point: point A to point B. A point-to-point switching topology is shown in Figure 3-4. Multiserver 5000 units can operate in a point-to-point switching topology over terrestrial, satellite, and microwave services at speeds ranging from 9.6 to 72 Kbps.
Multiserver 5000 OINT OINT Figure 3-5 illustrates a dual-link, point-to-point application. All traffic between Multiserver nodes is load- balanced between Link A and Link B. In the event of a single link failure, all traffic is automatically rerouted over the secondary link (link B). In a single-link, point-to-point application, the interconnect link can be configured from 9.6 to 72 Kbps.
CHAPTER 3: Network Design and Topologies TRING If several Multiserver units are strung together, a string topology is created (Figure 3-6). The limitations to this application are the following: • Maximum six hops • No closed loops Any or all of these may be Multiserver 5000 units. Three Multiserver units in a string can also be considered a “V”...
