Black Box 5000 manual Typical Point-to-Point, Dual Link with Load Balancing

Multiserver 5000

DUAL LINK POINT-TO-POINT

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. When load-balancing, each link must necessarily be slower that in a single-link application. So even though the aggregate link speed available might equal or exceed the single-link application, the slower links may limit the number or certain types of devices that can operate on the network. This will depend upon your particular application.
