A small Metasys network site comprises a single SNE or multiple SNEs, SNCs, and NAEs with one of the SNEs designated as the Site Director (Figure 1). See Site Director for additional information on Site Director hierarchy and the number of network engines a Site Director can supervise.
Larger Metasys network sites can comprise multiple SNEs and one or more ADSs or ADXs with access to multiple remote sites. On any site with one or more ADSs/ADXs, an ADS/ADX is designated as the Site Director. Figure 2 shows an example of a simple Metasys network with one SNE, one NAE55, and an ADS as the Site Director.
