Figure 35. Complex ATM Network Using ATM 8285
Figure 35 shows an ATM network mixing private and public environments. Grouping ATM switches into separate clusters limits your network restart time, limits the number of topology updates sent (as topology information remains within a cluster), and reduces the resources required on each node to maintain the network topology. ATM clusters in Figure 35 are interconnected in a bigger structure called a subnetwork to improve performances. Clusters are interconnected by parallel NNI connections increasing bandwidth (link aggregation) and offering redundancy.
